UEi Test Instruments CD100A Combustible Gas Leak Detector

I work as a technician for a heating and air conditioning company. This combustible gas detector is a professional-grade tool that works extremely well and is incredibly sensitive, and it's available from a variety of HVAC parts stores. It can detect almost any flammable gas at concentrations as low as 50 parts per million. br>br>It isn't automatic. I personally prefer zeroing. That is, it does not become desensitized to combustible gas when exposed to it. You can adjust the sensitivity as needed, which means you can lower it as the area becomes saturated with gas and you zero in on the leak, and then increase it at any time without having to wait a long time or restart the detector. It also means you'll need to adjust it to the required baseline when you first start it up, so give it a minute or two to warm up. Reduce the number of clicks per second to a few. br>br>So far, I've used this detector at least eight or ten times. It picks up right away, with no lag time. It quickly recovers. On both counts, it's a huge improvement over my previous detector. It's also insanely sensitive, like CRAZY sensitive; in a fun experiment, it's so sensitive that it can detect methane when placed close to anyone's rear end, even if they aren't passing gas. br>br>The point is, don't be fooled by the detector's extreme sensitivity. Even the tiniest "leaks" will be detected by it. I'd recommend using a bubble solution to double-check any leaks discovered by this detector. Not because the detector is unreliable, but because the leak may be so minor that it is unnoticeable. Typically, gas lines can only hold two people. On your side of the gas meter, 3 PSI of gas. They have been put to the test. At a pressure of ten pounds per square inch (PSI), the test was successful Gas lines, by their very nature, aren't particularly tight. If pumped to a pressure of 10 PSI, most gas lines will work. After a week, the pressure will have dropped significantly. My point is that if you find a leak with a gas detector but it won't show up with a bubble solution PROPERLY ADMINISTERED, it's probably nothing to be concerned about. On a small old house, you could look through the entire gas line. It could have a dozen "leaks" that small and still pass the pressure test. br>br>Another pointer: it's normal to smell a little gas from time to time. What? That can't be correct, can it? A pressure relief is built into your gas meter. It will occasionally purge a small amount of gas, particularly when gas appliances are turned on. off. It doesn't mean there's a problem just because you smell gas as you walk past the meter. When your gas furnace shuts off, the gas valve closes and the gas inside the distributor equalizes to ambient pressure, but because it's inside an enclosed tube, the inducer motor doesn't blow every last bit out of the flue. Everything goes dark, and the tiny amount of gas slowly dissipates over a few minutes. You'll smell gas if you open the door to your furnace's burner compartment at the appropriate time. It'll be picked up by this device. It'll slam into the orifices where the gas escapes in a big way. That isn't to say that there isn't a problem. br>br>What I'm getting at is, be cautious with gas, but be aware of how sensitive this detector is, and seek professional advice if you're not sure what is or isn't normal. This detector would be a welcome addition to the arsenal of tools for the professional.

At 14 months, you should stop smoking. The cost of fixing UEI was $100. I'm a seasoned home inspector, and I'd like to introduce myself. I take good care of my tools. This detector was something I really liked. I was reminded of the old tif8800 when I saw this. It worked in the same way that it did before, and it worked well. The nice thing about this one was that I didn't have to buy special batteries like I did with the Tif because I could just use a 9volt battery. For 14 months, I was satisfied with it until it stopped working. Its wheel had come loose, and I couldn't adjust it or turn it off any longer. UEI is the abbreviation for "United States Energy Institute. " who are known for providing excellent service - It was discovered that it was slightly out of warranty, and that having it repaired and shipped would cost just over $100. Because $100 goes a long way toward a new one, I decided to toss this one rather than invest another $100 in it. But, because I despise throwing things away, I opened it and was able to repair it myself. The wheel appears to have come loose from the control. On the screw, I used blue loctite and am hoping it will stay in place. In the end, Next time I need a gas detector, I'll look for one somewhere else; it would be nice if UEI would stand behind this product, but they didn't - The wheel and the holding screw both need to be redesigned.

It was difficult to choose between all of the available brands. Based on the reviews and specifications, I took a chance and purchased the item. After that, my HVAC contractor said that UEi is a great brand and that his testing equipment was UEi. (He gave it a try and found it to be enjoyable. ) There was a gas leak. br>br> The gas company had been out three times and had not been able to locate it. I tried using soap bubbles, but they didn't work. This unit was ordered out of desperation. The leak was quickly discovered. I'm not sure why people are upset that they have to take it outside to set the unit's baseline. Why care. It works. There isn't a simple push-button solution. Everything in life requires effort, and this unit was able to accomplish what the gas company's $500 unit could not. The beeping is loud, but when you're working with eqpt, such as a furnace, you want to know what's going on. It appears to be well-made and long-lasting. The sensor's light is ideal for seeing up between joists and behind pipes in dimly lit areas. I never imagined I'd own one, but I think I got the right gas sniffer. It doesn't say what kind of gas is present. As combustible gas concentrations increase, the rate of beeping/flashing light changes, letting you know when the leak has been discovered.

You've been a great help to me. You've aided me in completing numerous tasks with speed and accuracy. br>Este equipo es una obra de arte y es tan robusto que cuando lo llevo con me para hacer un trabajo, todos se impresionan por la calidad visual que muestra (yo, que lo uso casi a diario, puedo decir que es exelente en su funcionamiento). br>br>With this unit, I've detected gas leaks that jabón pumps haven't been able to detect, and I can use it in places where access is difficult. br>br>El sensor, according to the manufacturer, should be replaced every year, but due to the excellent quality of this product, I am able to replace it as often as necessary. (It has already been paid for a single task that I completed). br>I work as a restaurant equipment technician (ovens, fryers, and gas tanques). )br>I believe that if you use the sensor every day (365 days), it will change once a year. However, in my case, it doesn't matter because it's important that I'm certain (cálida=price). br>I've had others, but only this and another model I bought on Amazon are truly amazing.

I'm a technician who specializes in gas fireplaces. br>After 6 months of service, my unit just stopped working yesterday. br>I'm sending it in for a warranty repair today: (br>br>I had no choice but to send it in for repair. ) I was responsible for the shipping costs. When I got it back, it didn't work for more than a day. I had to return it on my own dime: (Waiting for it to come back. ).
