GMI GT-40, GT-41, GT-42, GT-43 & GT-44 Gas Detectors

GMI GT Series Multi-Functional Gas Analyser

The GMI GT Series is a multi-functional gas analyser range; each detector can be used for several different applications, eliminating the need for separate instruments for other tasks. Built to be durable and easy to use.

The Integral pump draws the sample in and includes a pressure sensor for gas flow detection. A hydrophobic filter protects the sampling system. Toxic gases are detected by electrochemical cells. Three sensor types detect methane: Semiconductor for ppm range, Catalytic Bead, 0-100% LEL and volume measurement by a Thermal Conductivity sensor.

Functions

  • Leak test
  • Confined space entry
  • Barhole testing
  • Carbon monoxide
  • Purge
  • Sniffer
  • Pressure leak tightness

Measuring Ranges

Gas / Parameter Range
CO 0 – 2000 ppm
H2S 0 – 100 ppm
LEL 0 – 100%
O2 0 – 25%
CH4 PPM 0 – 10,000 ppm
CH4 VOL 0 – 100%
Water Gauge 0 – 60 in. (0 – 150 mBar)

Features

  • Multi-application Gas Detector.
  • PPM, LEL and Volume range for CH4 leak detection.
  • Manual or automatic data-logging.
  • Audible visual 'Ticker' (Geiger) indication on ppm range.
  • Alarms: Audible 80 dB & visible LED flashing on both sides of the casing.
  • Integral flashlight.
  • Rechargeable or Alkaline battery (8 hours of operation either).
  • Charging is by plug or docking station.
  • Complete with a rugged Polycarbonate case, IP54 rated, suitable for outdoor use.
  • Operating temperature -20°C to +50°C.
