The portable GSP3 and GSP3 Flex (photo) gas detectors are designed for fast and reliable detection of leaks of inflammable gases at gas pipes and connections, gas meters, gas burners and gas tanks. The GSP3 Flex is equipped with a flexible gas probe to allow for the detection of leaks in areas difficult to access. The sensor is suitable for detecting methane, propane or butane, and covers the measurement range of 0 to 2,000 ppm (methane) at a sensitivity of 20 to 50 ppm. — Afriso-Euro-Index GmbH, Güglingen, Germany
