Introduction

The SR-3000 combustible and toxic gas detector uses a catalytic sensor, electrochemical sensor or optical ionic sensor, and is an independent detector based on a highly integrated embedded industrial microprocessor. The software is optimized with instruction design and the hardware features a modularization design. The detector is user friendly, stable and reliable. It is easy to be installed and has a strong anti-interference ability.

Application

Metallurgy, chemical industry, petroleum, gas storage, environmental protection and other industries related to flammable, explosive and toxic gases.

Features
  • CAN bus protocol communication interface makes it easy to ad hoc a network.
  • Sensors with fault self-detection and identification which can be replaced on site.
  • The remote controller can be used to control the gas detector
  • The upper and low limit alarm
  • Stable and reliable, strong anti-interference ability and is easy to install.
