Lowest temperature coefficient available, 0.2 %/C ensures predictable leak rates over a wide temperature band
Wide range of leak rates available, 10-3 to 10-9 atm-cc/sec. Specific leak rate values available to match your products leak specifications. Supplied with N.I.S.T. certificate at no additional charge
