HK-7200A Toxic Gas Detector

Supplies category：Toxic Gas Detector
Material code：HK-7200A
Manufacturer：HKY Technology Co.,Ltd.
 

Introduction

The Ex HK-7200A Toxic Gas Detector, based on electrochemical principle, is designed for continuous detecting and monitoring of hazardous gas leaks in ambient air and provides a 4~20mA output signal that can be connected to a controller, PLC,DCS or similar instrumentation.

Feature

 . ADVANCED MCU TECHNOLOGY.
 . SMT AND INGETAL DESIGN—Enhance performance and reliability.
 . CURRENT TRANSMISSION–Extremely extends the distance of signal transmission. 
 . CENTRALIZED POWER SUPPLY AND REGIONAL POWER SUPPLY 
 . LED DISPLAY—Display real-time concentration and operating statues of detector.
 . SIGNAL TRANSMISSION—Send measured concentration signal to controller.
 . INDOOR AND OUTDOOR USE—Suitable for the harshest environmental conditions.
 . UNIQUE MAGNETIC PEN DESIGN—Operate detector through magnetic pen. 
 . IMPORTED CATALYTIC COMBUSTION SENSOR—Advanced performance with stable measurement, high sensitivity, anti-poisoning, and resist influence. 
 . SENSOR DIAGNOSTIC FUNCTION—Provide alarm and prompt while sensor fault or ageing.
