The Hydrogen/Hydrocarbon Leak Detector & Monitor is useful
for snifing the ittings on your GC for leaking hydrogen or
Argon/Methane. It can also be used for detecting leaking natural
gas, propane, or other volatile hydrocarbons. Detection limit is
approximately 500ppm. TheH

/HC LeakDetector is also useful for
long term monitoring of hydrocarbon concentrations in a lowing
stream or static chamber. The sensor element is the same CCD
(Catalytic Combustion Detector) that is used as a GC detector on
SRI GCs.

increases, the voltmeter numbers increase. Byutilizinga voltmeter as a readout device, thecost of the leak
detector canbe kept low. Unlikeother leakdetectorswhichuse a rowof LEDs as a low resolution readout,
the voltmeter’s high resolution display allows the user to notice small changes which would be hard to
see on an LED display. The 115 volt AC unit comes with a 9 volt power supply, but can also be run on
battery power using any battery source with voltage between 8 and 15 volts DC. Power consumption is
approximately200milliamps. TheH

system for longer term strip-charting,monitoring, or data logging.
