It is widely used in the detection of ammonia nitrogen content in the fields of laboratory scientific research, farmland irrigation, domestic sewage and industrial wastewater. Low power consumption, wide linear range, excellent repeatability and stability. Ammonia is an important aspect of wastewater and environmental management. The 9512BNWP complies with SM 4500-NH3 D-1997 or E-1997; ASTM. The ZW-NH101 ammonia nitrogen water quality detection module is a general-purpose module, which uses the electrochemical principle to detect the ammonia nitrogen concentration in the solution to be tested. Using digital signal output, it is easy to use. The American Conference of Industrial Hygienists has set a limit to ammonia concentration in air of 25 ppm for. The online TDL gas analyzer ESE-LASER series measures trace gases using Tunable Diode Laser Absorption Spectroscopy.
