Portable leak detector
Varian Associates has released a new, PC-compatible model of its HeliTest portable leak detector, featuring an RS-232 port that enables remote operation and monitoring of test parameters by computer.
The HeliTest is designed to increase productivity and efficiency in manufacturing lines where high volume, repetitive testing is required. By pressurizing any system with inert helium, Heli-
Test can monitor and detect leaks accu rately in gas systems, fabrication gas
delivery systems or cryopump compressor/expanders. The portable, brief- case-size unit weighs 4.2 kg (9.2 lbs.), including its power source, and operates with the sensitivity and accuracy of a mass spectrometer in the sniffing mode.
HeliTest only registers the tracer gas helium, detects gas in concentrations as small as two ppm (less than the helium content of air) and can spot leaks as small as 5 10-6 mbar liters per second, even in a high helium background.
