GPD3000 – Gas Pen Digital

GPD 3000 is a leak detector for methane, propane, H2 and other combustible gases used for leak testing of gas vehicles, gas pipelines and gas canisters. The moveable sensor head allows measuring in tight spaces much easier. Depending on the task GPD 3000 will correctly display the gas concentration in ppm or Vol%. GPD 3000 is the most common equipment for checking leaks in vehicle inspection. We can perform accredited calibration in our laboratory (ISO 17025) as well as adjustments and repairs.
