Detector Option
The Precision 500 can be purchased along with a H
2
detector unit.
The detector is intended for use with a GC, it is recommended that the detector
unit is placed above the height of the GC outlet. The detector can be wall
mounted.
This unit is plugged, from the ‘In’ port at the rear on the detector, into the ‘H
2
Detector’ port at the rear of the generator, as shown below. This connection
will provide the detector unit with power and allows communication between
the Precision 500 and the detector unit.
The detector will take samples continuously and both the detector and the
Precision 500 will alarm if dangerous levels of hydrogen are detected, the
Precision 500 will then shut down.
Multiple detectors can be connected to one Precision 500, up to 4 in number. If
this is desired, connect the first detectors ‘Out’ port to the second detectors ‘In’
port, as illustrated below.
