Description

Overview

GAOTek high precision multi 4 in 1 smart sensor gas detector – adjustable calibrating level detects combustible gas, O2, and two other types of toxic gases continuously and simultaneously. It is ideal for areas requiring explosion-proof measures or prone to toxic gas leaks, such as underground channels or the mining industry. This device safeguards workers’ lives and prevents damage to relevant equipment.

 

Features

  • Advanced MCU control with low power consumption
  • Adjustable low and high alarm level
  • Adjustable calibrating level
  • High concentration protection for combustible gas
  • Self-test for the combustible gas sensor
  • Low battery indication
  • Replaceable sensor module
  • Self-adjustment function
  • Visual and audible alarm with vibration
  • STEL and TWA alarming for toxic gases
  • Advanced self-examination and self-renovation function
  • Password management to avoid wrong operation
  • Explosive proof housing
