Handheld Helium Leak Detector

Providing a low cost handheld helium leak detector for all your helium sniffing applications. The technology in the GasCheck includes a thermal conductivity sensor that allows detection of many gases (G3 Model Only) including helium, methane, refrigerant and argon. Sensitivity depends on the gas but is 100 times or more than the sensitivity of 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 with results are displayed on the LCD Display. LED indicator ( (on the G1 Model) and audible sound provides leak location. The 3 levels of GasCheck G1,G2 & G3, provide options for special user applications and requirements.

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 vs. the size of the helium leak. G1 is available in helium only.

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.

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
