Cal Check Canisters

Gas leak detectors use standard calibrated leak (SCL) fittings for easy and reliable calibration. Gases include H2, He, SF6, Refrigerants, and any other non-corrosive gas. Standard systems give leaks of 5 x 10-4 cc/sec, but can be lowered to 5 x 10-8 cc/sec using lower concentration gas cylinders. SCL's are also sold separately to build into your own calibration system.
