Greisinger GOO370 Oxygen Sensor for GMH 36xx Series 606854

The Greisinger GOO370 is an open oxygen sensor engineered for the GMH 36xx series handheld meters. It uses a galvanic cell to measure oxygen partial pressure in air and non-combustible gases, with a response time under 10 seconds at 25 °C. Unlike many sensors that require frequent recalibration, the GOO370 maintains a drift of less than 1% per month and offers a service life of approximately 2 years in ambient air.

Highlights

• Measurement range: 0.0 to 100.0 % O2
• Electrochemical galvanic cell sensing principle
• Automatic pressure compensation via connected GMH 36xx device
• 1.3 m cable with 6-pin Mini-DIN plug
• Operating temperature: 0 to 45 °C (sensor)

In daily use

The GOO370 connects directly to compatible Greisinger GMH 36xx meters, including the GMH 3610, GMH 3630, GMH 3650, GMH 3690, GMH 3691, GMH 3692, and GMH 3695. Calibration is a simple 1-point adjustment in ambient air (20.9% O2). The sensor head is housed in ABS plastic with IP20 protection, suitable for clean indoor environments. It is not intended for medical or diving applications.
