Gastec 25BE is an industrial-grade galvanic cell oxygen sensor manufactured by Gastec Corporation. Unlike single-use chemical colorimetric tubes (e.g., Gastec 31B), the 25BE is an electrochemical sensing element used in fixed-location gas monitoring systems and stationary oxygen deficiency alarms.
| Parameter | Specification |
| Sensor Type | Galvanic Cell (Electrochemical) |
| Form Factor / Mounting | Fixed-formula type |
| Dimensions | 36mm x 38mm |
| Weight | Approx. 110g |
| Target Gas | Oxygen (O2) |
| Power Requirements | Self-generating (No external excitation voltage needed) |
Instant Real-Time Measurement: Provides fast response times (T90) to rapid drops in oxygen concentration.
Fixed System Integration: Built specifically as an OEM replacement cell or dedicated sensor head for stationary oxygen monitoring panels and fixed gas alarm controllers.
Intrinsic Safety Compatibility: Low electrical output makes it naturally suited for intrinsically safe explosion-proof monitor designs
Oxygen Deficiency Monitoring: Installed in enclosed work environments, industrial plant rooms, and subterranean vaults to protect against asphyxiation risks.
Inert Gas Purging: Tracking residual oxygen levels in nitrogen-purged tanks, reaction vessels, and semiconductor manufacturing equipment.
Confined Space Monitoring Systems: Fixed wall-mounted safety terminals in chemical plants and storage facilities.
