The ZRT512J module is an intelligent refrigerant detection module based on infrared principle. It uses the Non - Dispersive Infrared (NDIR) principle to detect refrigerants, featuring excellent selectivity and no oxygen dependence. This module is a compact and high - performance product made by closely integrating mature infrared absorption gas detection sensors with micro - mechanical processing and sophisticated circuit design. It is easy to use and has excellent performance.

Application

HVAC refrigeration.
Industrial process and safety protection monitoring.

Features

High sensitivity, high resolution, and fast response time.
RS485 communication and relay control.
Temperature compensation, excellent linear output, outstanding stability, long service life.
Resistant to water vapor interference, non - poisoning, and can directly replace catalytic combustion principle modules.
