Sonda sensore gas Greisinger GGO370 compatibile con serie GMH 36xx, MPN 606852

Greisinger GGO370 is a closed gas sensor probe designed for use with GMH 36xx series instruments as a replacement or spare sensor (MPN 606852). The probe measures oxygen partial pressure and oxygen concentration and is suitable for measurements in atmospheric conditions as well as in gas-tight systems with minor overpressure or underpressure. It has an M16x1 screw thread for direct, gas-tight installation or connection via a hose adapter and connects to devices with an approximately 1.3 m cable and Mini-DIN plug.

Advantages

The GGO370 probe provides a compact design (36 mm × 95 mm) with integrated kink protection on the 150 mm version, quick response (T90) around the specified oxygen range and a sensor element (GOEL 380) rated for 12 months’ service life in air. It supports measurements of oxygen partial pressure from 0 to 11,000 hPa O2 and oxygen concentration from 0.0 to 100.0 % O2, and operates over a wide ambient temperature and humidity range.

Suitable for

• Field and laboratory oxygen measurements with GMH 36xx series meters
• Measurements in open atmosphere
• Measurements in gas-tight systems with small overpressure or underpressure (up to ±0.25 bar)

How to use

Install the GGO370 probe by screwing it into a matching M16x1 threaded port or use a suitable hose adapter to achieve a gas-tight connection to the measurement system. Connect the approximately 1.3 m Mini-DIN cable to a compatible GMH 36xx series instrument. Allow the sensor to stabilise according to the instrument’s instructions before taking measurements. Use the probe within the specified temperature, humidity and pressure limits to ensure correct readings.

Recommendations

For reliable long-term performance, avoid exposing the probe to condensing humidity, excessive mechanical stress or pressures beyond ±0.25 bar. Replace the sensor element after the indicated service life or earlier if drift or slow response is observed. Refer to the GMH 36xx instrument manual for calibration and maintenance procedures.
