Description

Overview

GAOTek wall-mounted hf gas detector is a high performance intelligent toxic gas detection alarm which adopted Membrapor sensor from Switzerland, high performance, supply couples of types of gas detection, low power microprocessor to ensure product performance and stability, real-time monitoring of the concentration of toxic gas. Mainly used in petroleum chemical industry, metallurgy, mining, fire, gas, environmental protection, electric power, communication, papermaking, printing and dyeing, food reserves, city water supply, sewage treatment, food, brewing, research, education, national defense and other places.

 

Features

  • Three kinds of signal output, 4 mA to 20 mA (three wire)
  • Digital / analog signal and switch at the same time
  • Big screen segment type LCD real-time display gas concentration
  • Gas concentration unit optional (such as ppm, mg/m3)
  • It has the instrument status, fault and communication abnormality prompt function
  • It can be set to a high and low alarm point, two level sound and light alarm
  • Two relays to control peripheral devices (such as the action of machine, sound and light alarm)
  • Round casting stainless steel housing is suitable for offshore platforms, high temperature, high humidity and other harsh environments
  • Good sealing, anti-corrosion, explosion-proof and anti-EMI, RFI function.
  • European design standards.
