GasCheck IS Intrinsically Safe Leak Detector

General Details

GasCheck – Rapid, Accurate Gas Leak Measurement

The Only ATEX Approved Gas Leak Detector

Designed specifically for the search and location of flammable gas leaks, GasCheck is the only ATEX approved, Intrinsically Safe gas leak detector on the market.

The GasCheck leak detector detects and measures almost any known gas, or gas mixture. Its advanced micro-thermal conductivity sensor responds rapidly to the smallest of gas leaks.

The GasCheck gas leak detector is conveniently calibrated against helium and is particularly sensitive to ammonia, argon, butane, hydrogen, SF6 and refrigerants. Its Intrinsic Safety proves an ideal tool for use in areas classified as zone zero flammable, and can safely detect flammable gases.

Robust, reliable and easy-to-use, the GasCheck gas leak detector has an LCD display, LED indicator and audible alarm to clearly indicate the detected gas leak. When switched on GasCheck automatically zeros to the ambient air and is ready to detect immediately.

The GasCheck gas leak detector is available in two distinct versions; the 3000is and 5000is with varied capabilities.
