hexafluoride Maintance for powergrid

QUALITEK`s sulfur hexafluoride (SF6) leakmeter is used to detect and quantify leaks in high-voltage switchgear, air conditioning components and underground cables. The non-degradable sensor is sensitive up to 0.01 ppm of SF6. The leakmeter comes with an RS-232 interface, a built-in battery power supply and an alpha-numerical 20-character display.
