GT40 Series Portable Gas Detector
Designed for the gas industry, the GT Series are multi-application
instruments, satisfying all the needs of service technicians within
a single unit. With 7 modes of operation, the GT Series is the most
versatile instrument available for working with gas.
The GT 40 series offers technicians and workers a single instrument
that can be used throughout the gas distribution and transmission
pipelines for all measurements needed for leak testing, and
confined space entry. Bright LED alarm lights illuminate as gas
levels increase, and audible alarms are activated at preset levels
should they be programmed.
Completely programmable, the GT is an industry standard throughout
the Americas and Europe and allows companies to utilize only one
instrument for all their monitoring needs. The GT series is
available with an optional docking station for full calibration and
testing capabilities, and printed cal certificates if needed.

1 instrument – 7 applications
Leak Test Mode – measures methane in three different distinct ranges (ppm/LEL/%Volume). Autoranging between all three ranges, audible, visual, and geiger alarms, and ergonomical design allows for easy one handed operation. Also ideal for carbon monoxide investigations.
Confined Space Mode – measures up to 4 gases (02, LEL, CO, H2S) simultaneously with audible visual alarms, datalogging, and min/max values.
Barhole Mode – for testing underground gas leaks. In this mode the GT measures gas beginning in the LEL range and autoranges to % Volume. Barhole probe included with instrument.
Carbon Monoxide Mode – measures CO directly in ppm. Menu items for air free CO (02 correction) when fitted with an 02 sensor, and differential CO.
Purge Mode – for measuring methane from 0–100% Volume in inert atmospheres.
Sniffer Mode – enables rapid leak detection by measuring methane from 0–10,000ppm with the semi-conductor fitted at the end of the flexi probe. Audible/visual geiger allows for easy pinpointing of leaking pipes.
Pressure Mode – measures from 0–60” of water column via a pressure sensor on the back of the instrument. Ideal for tightness tests on gas systems up to 2 psi.
