Designated Use
The GMH 3610 measures the oxygen concentration and the oxygen saturation in liquids.
For the measurement a external sensor of the type GWO 3600 is required. The measurement takes place at the
diaphragm head of the external sensor.
Due to the design of the sensor, the device has to be calibrated at regular intervals (e.g. at fresh air =20.95% oxy-
gen) to get accurate measuring values. If the sensor is used up, this will be detected at calibration and the sensor
element has to be maintained or replaced before the next measurement.
2 General Note
Read this document carefully and get used to the operation of the device before you use it. Keep this document
within reach for consulting in case of doubt.
