The Q198 portable SF6 leak detector is designed with non-dispersive infrared technology (NDIR) principle. Q198 can detect extremely low concentration of SF6 gas, which can achieve the fastest response and reliable measurement even in the case of minimum leakage, which is an ideal choice for detecting leak location and leakage rate.
Easy to operate and set parameters, Q198 has a 4.3-inch color LCD touch screen. At the same time, 8GB of memory is configured, the test results are saved in real time, and the data can be exported via Micro SD card. It has a built-in lithium battery, which can be charged for 8 hours in a row.

The instrument is easy to operate and has excellent stability, including the two parts of the probe and the machine. The probe is equipped with a sampling pump, which can be continuously inhaled, and the sample will enter the sensor through the sampling port. The probe is connected with a telescopic line to facilitate mobile detection and leakage. The device is equipped with a 4.3-inch touch screen, easy to view the detection data and easy to set parameters.
