Air analyzer GMH 3695

oxygengasfor ambient air

Overview
Oxygen meter for oxygen measurement in air and gas mixtures with integrated temperature and pressure measurement. Partial-pressure O2 sensor housed in a dedicated enclosure.

GMH 3695
The GMH 3695 measures oxygen in air and gas mixtures either as partial pressure or as concentration in % vol. An external sensor of type GOO-... or GGO-... can be connected via the MINI-DIN socket. Due to sensor characteristics, regular calibration (for example using fresh air = 20.95 %) is required to obtain accurate values. End-of-life of the sensor is detected during calibration; the sensor must be regenerated or replaced before further measurements. Observe applicable safety rules. Use the device only as intended and under suitable conditions; handle with care (do not throw, strike, ...). Protect the device from contamination.

Safety policy
This device has been designed and tested according to safety regulations for electronic equipment. Reliable operation and performance are ensured only if common safety measures and the specific instructions in the manual are followed during use.

Application of GGO sensor types
For measurements in ambient air and systems without positive or negative pressure, the GGO sensor is sufficient. The GGO can also be firmly screwed into systems with low positive or negative pressure. Observe maximum pressure and pressure difference at the membrane: if device and sensor pressures differ, connect the device pressure port to the measurement pressure to avoid incorrect compensation.

Sensor calibration
To compensate sensor aging, calibrate at regular intervals. The device includes an easy-to-use calibration function. It is recommended to calibrate the sensor at least every 7 days or before each series of measurements for maximum accuracy.
