The GasCheck G gas leak detector represents the latest in gas detection technology: its advanced system of micro thermal conductivity enables advanced sensitivity for the rapid, effective detection of gas leaks down to cc/sec, mg/m³ or ppm levels. Designed for the search and location of gas leaks, the GasCheck G leak detector provides you with effective detection of almost any gas or gas mixture. Robust and reliable, the GasCheck G leak detector gives stable, repeatable readings of the detected gas. The instrument’s LCD display, LED indicator, and audible sounder clearly indicates the gas leak present.

GasCheck G automatically zeros to the ambient air around it when switched on and is ready to detect immediately. The instrument’s easy to use graphical interface and intuitive keypad allows for simple function, selection, and adjustment.
