The Model 196 Leakseeker uses a micro-volume thermal conductivity cell to pinpoint and quantify trace amounts of most nontoxic gases including helium, carbon dioxide, argon and refrigerants down to 1 x 10-5 atm cc/sec in less than a second. The lightweight nozzle probe can be detached from the hand console, which contains the battery power pack, for complete freedom to detect leaks in complex systems. In fixed station applications, the console unit can be bench mounted and the ac adapter used to provide power to the unit.
