Concentration Meters

Concentration meters, or catharometers, measure the concentration of a gas in a binary mixture by thermal conductivity. They are mainly used to monitor helium concentrations during so-called “envelope” (hood) leak tests, and argon concentrations during passivation operations. They are available as portable versions or as 19″ rack units with an ATEX cell for fixed installations.

Which detector for which gas?

Refrigerant gases leak detector: leak detection of HFC, HFO and HC gases, for maintenance, expert analysis and production.
N2H2 tracer gas leak detector: non-destructive leak testing of installations and networks with the nitrogen-hydrogen mixture (H2/N2, Nidron).
CO2/R744 leak detector: leak detection on CO2 installations, using infrared technology.
Helium & argon leak detector: leak location by thermal conductivity during non-destructive testing, for expert analysis, in laboratories and in industry.
Underground leak detector: non-destructive leak location on underground pipes using H2/N2 tracer gas.
Concentration meters: measurement of the helium, argon or oxygen content of a gas mixture.
To check or calibrate your detector: test leak, calibrated leak, EN 14624 calibrated leak or calibrated gas.
