GMH 3692 Air oxygen meter without sensor
features
- Alarm monitoring with integrated horn
- Ambient pressure compensation with integrated barometer
Temperature compensation : automatic via temperature sensor integrated in the sensor housing. Air pressure compensation: The O2 concentration is automatically compensated with the integrated pressure sensor.
Calibration : 1-point calibration: easiest adjustment to atmospheric air. (Device is adjusted to 20.9% by pressing a button).
2- / 3-point calibration : first point in air (20.9%), second and third 0 or 100%. Calibration Interval: After a selectable period of time (1 ... 365 days or inactive) a recalibration is requested.
GMH 3695: additional calibration history Analogue output (only GMH 3695): 0 ... 1 V, freely scalablePressure connector (only GMH 3695): for pressure compensationData logger (only GMH 3695): Cyclic: 8000 data sets, cycle selectable: 1 s ... 60 min Single: 1000 data records, with measuring point input
applications
