Gas analysis does not always happen under the same conditions. This sensor family gives users the right housing concept for the measuring task: GGO for atmosphere and systems without relevant pressure, GOO for gases flowing around the sensor, and GOG/ResOx for sampling small gas probes with a gas sampling pump.
The variants support oxygen measurement in conjunction with compatible GMH instruments. Depending on the sensor element, the family covers 0.0 … 35.0 vol.-% O2 for applications with high CO2 concentrations or 0.0 … 100.0 vol.-% O2 for low oxygen and concentrations above 35 vol.-% O2 where larger CO2 content is not present.
Practical details support reliable work in the field and at the measuring point. The GOO design helps measuring gas stream around the sensor without pressure build-up, while GGO housings can be screwed tightly into systems with small overpressure or underpressure within the specified limits. An integrated temperature sensor is included in the cable connection.
GGO is a closed housing, GOO is an open housing with drillings, and GOG/ResOx is a specialized gas sampling housing.
GGO, GOO and GGA 370/381 variants are for GMH 369x instruments; 570/581 variants are for GMH 569x instruments.
GOEL 370 uses acidic electrolyte. GOEL 381 uses basic electrolyte and is intended for applications without larger CO2 concentration.
GGO can be used at atmosphere and in systems without overpressure or underpressure. It can also be screwed into systems with small pressure differences.
GOG/ResOx housings are designed to sample and analyze small gas probes by means of a gas sampling pump.
The connection uses an approx. 1 m cable with an integrated temperature sensor.
