GT SERIES

Features Parts

Portable Gas Monitor for One, Two, Three or Four Gases
 


GT Series of portable gas monitors are designed to protect workers from hazardous gases in confined spaces and other industrial work sites. The monitors are available in eight different gas combinations for detecting hydrocarbons in the LEL/PPM range, oxygen content, carbon monoxide, hydrogen sulphide and other gases.
Microprocessor electronics and convenient top-mounted switches make operation and calibration simple. Each GT Series monitor feature two programmable levels of alarm with audible and visible indications. This instrument also features a built-in datalogger and a rugged RFI resistant housing.
