ION Science GasCheck G

Handheld Gas Leak Detector

Ion Science’s GasCheck G is a handheld VOC gas detector which features fast and accurate detection of gas leaks. The GasCheckG can detect almost any known gas or gas mixture and is particularly sensitive to ammonia, argon, butane, helium, hydrogen, and SF6.

Designed for search and location of gas leaks, Ion Science’s GasCheck G features an advanced micro thermal conductivity sensor for fast and efficient detection of almost any gas or gas mixture.

The GasCheck G provides repeatable, stable readings of any detected gas. The presence of a leak is clearly indicated via the instrument’s LCD display, LED indicator, and an audible sounder. GasCheck G automatically zeros to the ambient air around it when turned on and is immediately ready to detect gases. An easy-to-use graphical interface and intuitive keypad allows simple function, selection and adjustment.

GasCheck G is upgradable throughout the range, and comes in three distinct versions—G1, G2, and G3—each with varied capabilities. Features, outlined below, may be added without returning the device to the factory.
