This ammonia (NH3) gas sensor detects the concentrations of NH3 in the air and ouputs its reading as an analog voltage. TCB2 series point gas detectors can be combined in four or one in five according to different gases. They are manufactured using convenient wireless remote control operation technology, high-performance sensors combined with sophisticated SMD process, and the instrument has good repeatability and temperature resistance Humidity interference, long service life, easy operation and other advantages.
TCB2 point type gas detector adopts two-wire or four-wire system structure, and the monitoring results can be checked away from the scene by monitoring instruments or controllers. It is suitable for online real-time monitoring of toxic gases and flammable and explosive gases in various environments. The all-in-one combination can intuitively detect the concentration of multiple gases through the LCD screen and display them separately.
