The GT Series is a range of Portable Gas Detection instruments that combine quality, ruggedness and advanced technology in a user friendly, hand-held gas detector. It has been designed for the gas industry, satisfying all the needs of service technicians within a single unit.

Applications: Leak test, confined space entry, barhole testing, carbon monoxide, purge, sniffer pressure leak tightness

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

Seven functions are possible:

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

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.

Measuring Ranges

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