Product Overview
Description
The on-site power supply adopts 10~30V DC wide-voltage power supply, supports a variety of gas detection, and the range can be customized;
The gas transmitter adopts imported fifirst-line brand electrochemical sensor, which has the characteristics of rapid response and strong anti-interference ability;
Wide voltage 10-30V DC power supply, standard Modbus-RTU communication protocol 485 signal output, address and baud rate can be set, the communication distance is up to 2000 meters;
Using remote infrared remote control technology, after our unique compensation algorithm, multi-stage standard gas
calibration, it also has the characteristics of long life, high precision, high repeatability and high stability;
Optional high-quality LCD screen, the value can be viewed directly on site, and can be displayed clearly at night.
