Calibrated reference leaks for calibration of leak detectors

Ceramisis supply a complete range of Helium and refrigerant gas, calibrated reference leaks and accessories for use in leak detection and calibration of equipment. Leak detector mass spectrometers for Helium and Freon gases that are used for on site leak detection of installed process pipe work and systems, need calibration on a regular basis to maintain their accuracy. Our range of reference leaks are available as single items or as a complete set depending on your requirement.

Calibrated to the National physical laboratory standard via DERA (Defense research establishment)
Calibration suitable for the Nuclear industry
Fast track on re calibration of existing leaks
Numerous types and styles available
Market leading, highly accurate leak detection sniffer and spray probe as optional extras
Leaks can be mounted into any type of flange fitting suitable for your industry
Single items or complete kits available
kits and leaks are usually available ex stock for fast order completion
Please use the links on the left for leak detection accessories
