GDWG SF6 Gas Leak Detecting and Measuring Systems high precision and sensitivity detecting system, which use NDIR technology principle and pumping cycle principle. It is used to detect few SF6 gas in the pipe quantitatively and qualitatively. Based on the design principle of infrared (detecting SF6 gas wavelength 10.2-10.6μm), the SF6 detection will be accurate.
Features
3.5inch OLED display.
One screen display SF6 gas concentration, temperature and humidity, battery indication, time and pump status.
Friendly human machine interface.
Fast measurement speed, up to10s to achieve stable data.
Only response for SF6 gas, not for other gas.
Make sure that no sensor poisoning occurs at any concentration.
Small size, easy to carry, suitable for on-site working.
Super-light aluminum with full shielding shell.
Diaphragm pump suction sampling mode to ensure the tightness of the test gas path.
