GasCheck G - Portable leak detector

GasCheck G - Portable leak detector



GasCheck G is a device designed for detecting gas leaks, equipped with an advanced micro-sensor suitable for detecting almost all types of gases. It provides accurate and reliable readings, signaling leaks through an LCD display, an LED indicator, and auditory alarms. The interface is intuitive, and the device is user-friendly, featuring a large backlit LCD screen. It is especially sensitive to gases such as ammonia and hydrogen. Users have the flexibility to choose from different reading modes, and the sensitivity can be expanded.

GasCheck G is available in two versions, G2 and G3, which can be easily upgraded without sending them back to the manufacturer.
