Hydrogen/Hydrocarbon Leak Detector/Monitor

  • Detects Hydrogen and Hydrocarbons down to 500ppm
  • Find leaks or monitor Hydrogen and Hydrocarbon concentrations
  • Plugs into most Voltmeters for a digital readout


The Hydrogen/Hydrocarbon Leak Detector/Monitor is useful for sniffing the fittings 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. This leak detector/monitor is also useful for long term monitoring of hydrocaron concentrations in a flowing stream or static chamber. The sensor element is the same CCD that is used as a GC detector on SRI GCs.
Hydrogen/Hydrocarbon Leak Detector/Monitor

The H2-50 produces 50 milliliters per minute of hydrogen gas at 35psi using readily available distilled water from grocery and convenience stores. The H2-50 can supply enough hydrogen gas for two FID detectors, in addition to providing the GC carrier gas. During operation, it also stores enough hydrogen gas to operate a split injector for short periods.
Hydrogen/Hydrocarbon Leak Detector/Monitor
The leak detector/monitor is attached to your existing voltmeter to provide a digital readout. As the H2/HC concentration increases, the voltmeter numbers increase. By utilizing a voltmeter as a readout device, the cost of the leak detector/monitor can be kept low. Unlike other leak detectors which use a row of 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 110 volt AC unit comes with a 9 volt power supply, but can also run on battery power using any battery source with voltage between 8 and 15 volts DC. Power consumption is approximately 200 milliamps. The H2/HC leak detector/monitor can also be built into the Model 203 PeakSimple data system for longer term strip-charting, monitoring, or data logging.
