Filter-Check Valve Combination

During measuring operations with the RITTER MilliGascounter, the gas inside the counter flows through a capillary with an inner diameter of 0.4 mm. Particles and other contaminations can block this thin capillary. To prevent any possible blockage, a Filter-Check Valve Combination can be provided by RITTER.
