Graftel designs, manufactures and calibrates a full line of LRM testing instrumentation. Our Local Leakage Rate Testing Systems are a compact, light weight and rugged rig used for performing flow make-up or pressure decay Type B and C tests on valves, flanges, airlocks and other containment barriers.
Our state-of-the-art units utilize all digital flow instrumentation. The microprocessor based laminar flow elements may be relied upon to accurately and repeatability measure air or nitrogen flow. Flow rates are direct reading in units switchable between scfh, slm or sccm. Either air or nitrogen may be used. Pressure and temperature effects are automatically compensated for, no correction factors are ever required.
