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.
