For many refrigeration applications, using solid state sensors will provide an economical and reliable gas detection solution. Solid state sensors are reliable if used in a clean area with very little temperature and humidity changes. Solid State refrigerant sensors should not be used where there are other chemicals or gases present (other than refrigerants), such as alcohol based cleaners, fumes from running engines, fuel storage containers, etc.

Using infrared sensor technology will ensure the highest degree of sensor accuracy if monitoring an area where there are other  contamination gases or multiple refrigerants in the same area. Infrared refrigerant sensors should not be used in locations that have corrosive chemicals such as chlorine, ammonia and other oxidizers that are present, especially if there is a higher humidity level.

NOTE: Ammonia is commonly used as a refrigerant in very low temperature applications such as food/meat processing, ice making plants and ice arenas. Electrochemical sensors are required to ensure accurate monitoring in Ammonia applications.
