Handheld Helium Leak Detector

Handheld Helium Leak Detector

The GasCheck is a low cost handheld helium leak detector for helium sniffing applications.  Technology in the GasCheck includes a thermal conductivity sensor that allows detection of many gases (Model G3 only) including helium, methane, refrigerant and argon. Sensitivity depends on the gas, but the GasCheck is 100x more sensitive than bubble emission testing. Battery operation (4 AA Batteries) allows for true portability. Accuracy of +/- 5% with display reading of one decimal provides quantitative leak checking. Factory calibration is provided for each unit during manufacture.

The GasCheck handheld helium leak detector provides reliable leak detection readings of the selected gas while displaying results on its LCD Display. LED indicator and audible sound provides leak location. The GasCheck zeros itself to the background of the selected gas when switched on. The 3 levels of GasCheck G1,G2 & G3, provide options for special user applications and requirements.

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.

There are three models of the GasCheck, G1, G2 & G3 with the G2 & G3 providing additional features of operation. The G1 provides an audible alarm that increases in frequency in relation to the size of the helium leak. G1 is available in helium only.

Upgraded features of G2 & G3

• G2- Quantitative leak rate display, peak hold of largest leak rate detected & calibration available. You can also choose a single gas to detect from the list of gases.
• G3- Everything in the G2 plus- Measure 20 additional gases with the on-board menu of gases, data logging of up to 10 readings, Readings displayed in cc/ sec,g/yr,ppm or mg/m3 & selectable battery type
