DTS A001 Fixed Gas Detector - Henan Duotesi Electronic Technology Co., Ltd.

Product Introduction

The point-gas detector is a new on-line detection instrument produced by our company. This machine adopts high light digital display, high decibel sound and light alarm, and high-performance imported sensor. Detection principle: electrochemical, catalytic combustion, infrared, PID, semiconductor, etc.,and it can detect more than 500 kinds of gases.The performance of this product is stable, accurate accuracy, long life, easy to operate.

The point-gas detector converts the gas concentration in the air into digital signal, which can output standard (4~20) mA current signal, or two-line and four-line RS485 (MODBUS-RTU) signal, which can be compatible with secondary instrument. PLC, DCS system, data acquisition module,with the characteristics of long transmission distance and good anti-interference performance.
