H2O2 Hydrogen Peroxide Gas Sensor Detector 100 ppm Portable Devices Electrochemical Toxic Gas Compac

Gas Module Introduction
FAD gas module with two/three wire TTL/0-20mA/RS485 output, integrates toxic gas sensor + transmitter board. Adopting imported advanced electrochemical gas sensors, it has features of high accuracy, long lifetime, high stability and high anti-interference. The module is designed to prevent circuit reversed connection, high voltage, high current and lightning.
