Answer: Yes, it detects refrigerants.

Q2.How to use a CD100A Combustible Gas Leak Detector?

Answer: Turn on the gas leak detector and let it warm up for 10 seconds in the open air. Pointing the gooseneck toward suspected areas. The detector being well designed will provide both audio and visual cues by increasing the tic rate if the leak is detected. The Gas Leak detector can be used for both industrial and residential environments

Q3.Can it detect sewer gas?

Answer: The user manual lists the gases it detects. Among them are hydrogen sulfide, ammonia, and methane. These are three of the main components of sewer gas. So yes, this gadget does detect sewer gas.  Minimum detection of 50 ppm methane for this item.

Q4.How do you know what kind of gas it’s detecting?

 Answer: CD100A is just like a majority designed to detect general combustible gas. It cannot detect which particular gas, as comes with one sensor only. It tells you about the presence or a leak of combustible gas, or gas that can be ignited. As a tester, it served the purpose of warning users about the presence of dangerous gases, which can cause fire fender-bender.

Q4.Does this recharge, or have replaceable batteries?

Answer: Replaceable batteries that last long and serve the purpose well. Great tool! You can buy those batteries from Amazon. You can replace it yourself

Q5.How long do you need to warm up?

Start your testing by setting the instrument in the fresh air. The red  LED indicator will flash in correspondence with the tic rate. Allow about 10 seconds for the sensor to stabilize indicated by a steady tic rate. (It may require up to two minutes to stabilize). 

Q6.To be clear, will this pick up CO (carbon monoxide) in addition to those chemicals listed? If so, what range of gas levels can it detect?

Answer: “The CD100A does not detect CO”. And it starts detecting combustible gases at 50ppm or more.”

Q7.What are the signs that indicate the sensor needs to be changed?

Answer:  The tic rate becomes uncontrollable and probably shows the sensor needs to be changed

Q8.Can you manually change the sensor by yourself?

Answer: Yes you can change the sensor by yourself. All you have to do is
