NDIR so2 leak check for transformers

Product Description. Portable SF6 Leak Detector Based On NDIR Technology doesn't call for any consumables and not require maintenance in the cycle of calibration. This type of leak detector has the capability to detect very much low concentration of SF6 gas, which can attain the quickest response as well as reliable measurement even if minimum leakage occur, which is a perfect selection to detect leakage rate leak location.
