The GPM features a 5.7” LCD screen for a clear view of the monitored Oxygen level.
Oxygen level can be displayed in Percent (%) or Parts Per Million (ppm) user-selectable.
The Zirconia Oxygen Sensor can measure Oxygen levels from 5% down to 0.0001%
(50000 to 1 ppm). Data-logging of the Oxygen level and operation time directly on to a 4GB Pen Stick Flash Drive can be programmed by the user to record at pre-set intervals.
The GPM is housed in a rugged die-cast aluminium case. Outputs are provided for optional external warning beacons, proportional output together with changeover relay contacts for clients own warning systems.
The 5.7” LCD Display provides a clear readout of the monitored data together with an on-board printout of the logged data.
The proportional output can be programmed to output a dc voltage of 0 to
5vdc (0-10V DC and 4-20mA optional) over a pre-programmed oxygen level range.
High/Low Alarm Limits can be programmed by the user to provide external signalling via the Alarm Outputs on the GPM.
