Product Introduction
The 6-IN-1 gas detector is a new type of gas detector produced by our company. It adopts a modular sensor design that requires no calibration. The product settings are stored in the sensor module, making replacement and after-sales maintenance convenient. It offers excellent repeatability and temperature/humidity characteristics, long service life and easy operation, and is suitable for detecting gas concentrations in industrial environments.
The detector converts the concentration signal of the target gas in the air into a digital signal for display. It provides a three-wire 4–20 mA current signal and RS485 signal output, and can optionally be equipped with wireless communication, allowing users to choose according to their needs.
