How Important Is the Extended Range Feature of the Minirae?


The MiniRAE 3000 is recognised as the most advanced hand held portable volatile organic compound (VOC) detector available today. It includes many innovative features which, combined with its handy small size, set it apart from other VOC detectors on the market. In this article we will be focussing on just one of these features, the extended range of 0 to 15,000 ppm of the Photoionisation Detector.

But first, let's take a quick look at the other fantastic features of the MiniRAE 3000. The MiniRAE 3000 can be used anywhere, and is able to give real-time readings straight to a base controller that can be located up to 500 feet away, using a built in RF Modem. The large display of the MiniRAE 3000 is the perfect size to quickly view comprehensive information including the gas type, concentration and correction factor. The MiniRAE 3000 includes an integrated flash light, enabling the VOC detector to be used in any environment or setting, making it perfect for use in emergencies.

The rugged, durable housing and construction of the MiniRAE 3000 also make it appropriate for use in extreme environments; the waterproof design allows it to be easily cleaned and decontaminated in water and the strong, removable rubber boot protects the inner workings of the detector from rough handling and accidents. Every design and technological aspect of the MiniRAE has optimised it for safe, effective and easy use in any situation.

The MiniRAE is unique for its 350 compounds correction factors list. This is the most comprehensive chemicals list of any PID, making it the most versatile and sensitive VOC detector yet. The extended range, from 0 to 15,000 ppm of the PID complements and amplifies this versatility. Standard PIDs only detect volatile organic compounds in concentrations up to 10,000 ppm. The extended range of the MiniRAE makes it useful in more applications than standard detectors, such as industrial hygiene, leak and hazardous materials detection, environmental contamination detection, arson investigation and taking lower explosive limit measurements.

The design of the Photoionisation Detector used in the MiniRAE 3000 is unique, guaranteeing that the results it gives are as accurate as possible. The extended measuring range is complemented by improved linearity, meaning that the MiniRAE not only detects gases at a wider range of concentrations but also maintains its excellent accuracy at very low and very high concentrations. The accuracy and sensitivity of the MiniRAE 3000 is even assured in differing humidities and temperatures. The detector features inbuilt humidity and temperature sensors to overcome the 'quenching' effect high humidity normally has on VOC detectors.




These are few features we read above and there is much more about MiniRAE 3000 to know what makes it useful for manufacturing industries. Active Environmental Solutions make available a quality range of products for manufacturing industry like gas detectors, environmental monitoring products, Noise Dosimeters from leading international manufacturers of Australia.

LG Over the Range Microwaves - Four Models Reviewed


LG over the range microwaves are revolutionizing the industry with their innovative advances like the development of a Warming Lamp to keep entrees warm and their Glide and Spin cooking trays to assure that your food cooks more evenly.

The idea for the first microwave came about in 1945 when an engineer was working on a device and found that the chocolate bar in his pocket had melted. This was due to the microwaves. He then experimented with popcorn kernels and through trial and error he discovered what foods could be cooked this way. By the 1970s, microwave ovens had made great strides and, for many, they were no longer considered a luxury; they were considered a necessity.

Today, microwaves continue to evolve and many busy families depend on them to cook their meals. They are quick, easy and they save energy. There are currently ten LG over the range microwaves to choose from and they each offer a variety of features.

Outdoor Long Range Infrared Night Vision Cameras to Protect Your Home


When you hear something outside your home at night, and are trying to determine the cause, the automatic thing to do is usually to turn on lights and peek through the blinds. Unfortunately, this method of checking outside, albeit the most common, actually just lets whomever is outside see you. There is a much better method of being able to see exactly who is outside your home at night, even if it is completely pitch black. Using specially designed outdoor Infrared night vision security cameras, can provide you with a clear video feed of what is happening, so that you can safely watch your home and alert authorities if needed, without letting on your position to anyone who is outside.

Long Range Infrared night vision cameras employ infrared style LEDs or arrays that will illuminate the area in front of the camera with an invisible infrared light. This light is not visible to the human eye, but is visible to the image sensor of the camera. IR light will allow the camera to see in black and white during the nighttime hours, so that the camera can clearly see everything that is happening. Long range versions of these infrared night vision cameras can even deliver IR light that can be seen by the camera up to 100, 150 or 200 feet away from the camera. These cameras have more powerful IR LEDs for greater illumination, and often have lower light image sensors as well.

When selecting a long-range night vision security camera, it is important to understand that the range of the camera is rated by the distance under ideal conditions that the IR light will reflect back to the camera and provide a picture. At 72° F with 0% humidity, the rated distance will be the distance that the IR light will stop reflecting back to the camera. In order to deliver the best picture quality and clarity, it is highly recommended to keep the object being viewed between 60-80% of the maximum rated infrared range. This will help to compensate for changes in temperature and humidity and still deliver a good picture quality at night.

Another consideration to keep in mind when you are selecting a night vision camera, is the lens that will be used. Having a long range infrared camera will not really help you if the camera has a fixed lens that is a wide angle view. This is because even though the camera may be rated at 100' or more for IR light, that rating does not say anything about how large something will appear on the screen. With a wide angle lens at that distance, items on the screen will be very small and therefore almost impossible to distinguish. That is why many of the better quality Long-Range IR cameras will come with what is called a varifocal lens. These lenses have the ability to adjust the zoom and focus of the camera, allowing you to custom-tailor the width of view as desired to provide the best distinguishing characteristics.




At Platinum CCTV, our latest line of long range infrared night vision cameras deliver great quality video with 700TVL Sony CCD Image sensors, and all of them also have adjustable varifocal lenses to help deliver the best quality video for your home or business security camera system. Our CD-9361Outdoor Long Range Infrared Bullet cameras have up to 200' infrared night vision, and our CD-8361 Outdoor Armor Dome IR Security Cameras are a great choice for a smaller footprint dome installation.

The New Frigidaire Dehumidifier Range - Improvements and Flaws


The new Frigidaire dehumidifier range includes three models; the 70 pint FAD704DUD, the 50 pint FAD504DUD and the 30 pint FAD301NUD. Unlike the "new" ranges marketed by some other manufacturers the DUD/NUD units from Frigidaire are significantly different from the models they replace.

The most obvious difference is that the FAD251NTD, a 25 pint dehumidifier, is replaced by the 30 pint FAD301NUD. This may seem relatively unimportant to the casual observer but there are two reasons why the small increase in capacity is of significant value to consumers.

1. The Energy Star qualification requirement, the Energy Factor (EF), for a 30 pint dehumidifier is 1.4 litres (of water extracted) per kilowatt hour of energy used (1.4Lt/kwh). The equivalent EF for a 25 pint unit is 1.2 Lt/kwh. This means that the larger capacity FAD301NUD removes nearly 17% more water from the air for every energy dollar you spend, a considerable saving.

2. Low capacity dehumidifiers are generally less popular in North America than the more powerful 50 pint and 70 pint models as the main application for portable dehumidifiers is in the basement, which in most homes is typically an area of 800 to 1200 square feet. Lower capacity dehumidifiers are more often used in smaller areas within the home or, in some cases, in a recreational vehicle (RV). In these locations the noise produced by a dehumidifier can be more intrusive and while the 30 pint model is no quieter than its 25 pint predecessor its larger capacity means that it will run for fewer hours per day in a space of given size causing less noise nuisance.

Despite its higher capacity the new 30 pint Frigidaire dehumidifier is slightly smaller in all three dimensions than the 25 pint FAD251NTD. Both the 70 pint and 50 pint "DUD" models are also more compact than the models they replace. In a basement the modest reduction in size may be relatively unimportant for many but in a bedroom or RV it will be much appreciated by the majority of users. I have already touched on the subject of dehumidifier noise and, since this has as much to do with noise quality as sheer volume, the main source of information on the noise "level" is the increasing number of dehumidifier reviews written by consumers about the new range.

It is clear from the hundreds of published reviews that the new Frigidaire Dehumidifier range has impressed large numbers of owners with its relative quietness when compared with other brands and the preceding models. Noise from dehumidifiers is unavoidable but with this range Frigidaire appears to have done its best to minimize the discomfort. It should be noted that there is a marked difference in reported noise level between the higher (louder) and lower fan speeds on all three models.

There is always a down side and there are two aspects of the new Frigidaire dehumidifier range that have disappointed many customers.

1. All three models cycle on and off very frequently. To be fair this is a curse that seems to afflict all current dehumidifier models but it is a source of concern because of the additional strain it places on the compressor and the rest of the refrigeration system. This may be a result of humidity sensors being too sensitive and/or because the sensor is measuring the humidity of the air inside the dehumidifier casing which may be higher than that of the air in the room. Whatever the cause it is an issue which all dehumidifier manufacturers need to address.

2. Users of the 50 pint and 70 pint models in the new Frigidaire dehumidifier range have reported problems with the continuous drainage option available on these models. This seems to result from the relocation of the discharge port for the water to the rear of the dehumidifier casing. Frigidaire have responded to this problem with a "fix" in the form of a new drainage kit which is now supplied with both these models and has apparently solved the problem.

Frigidaire is to be congratulated on having the courage to introduce a genuinely new range to replace models of proven success and popularity. Perhaps the flaws are the price of that courage but the new range offers significant advantages over the older models and the Frigidaire dehumidifier remains one of the most competitively priced, popular and successful brands in the North American home dehumidifier market.
