Product Description

OEM Measurement Ammonia Concentration Sensor NH3 leak detection Sensor

Our company provides two types of ammonia sensors according to the different measurement specification: ammonia sensors and 3in1 (ammonia, temperature humidity) sensor. Normally ammonia sensor installed in a place where the ammonia is easy to leak. It is judged by the specific gravity of the gas being tested relative to the air. Our factory is engaged in producing gas detection over 15 years, so we accept to OEM. The wall-mounted ammonia sensor is made of waterproof shell and dust-proof probe being used in harsh environments.
