The SF 6 LeakCheck P1:p is an award winning SF 6 gas leak detector that uses negative Ion Capture (NIC) technology designed for location, leak testing and measurement of SF 6 leaks in high electrical switchgear. The SF 6 gas leak detector rapidly detects leaks down to 1 x 10 8 ml/sec with a quick clear down of less than 1 second. The leak detector is unaffected by the exposure to large leaks and will continue to remain uncontaminated even after the exposure to 100% SF 6 gas.
