PRODUCT DESCRIPTION



    1. Product overview

The transmitter is widely used in air quality testing equipment, breeding systems, public toilets and other occasions that require NH3 and temperature and humidity monitoring. The input power supply in the sensor, the sensor probe, and the signal output are completely isolated. It is safe and reliable, beautiful in appearance and easy to install.

The sensor uses more advanced and expensive electrochemical probes, which have higher accuracy and stability than traditional semiconductor probes.


    1. Features

This product adopts high-sensitivity imported semiconductor gas detection probe with stable signal and high precision. It has the characteristics of wide measuring range, good linearity, easy to use, easy to install, and long transmission distance.
