TOC-750S Aspirated Gas Detector
The TOC-750S Sampling Fixed Gas Detector is an addressable sampling gas detector that enables gas detection in challenging or hard-to-reach areas.
Thanks to its internal piezo pump technology, it contains almost no moving parts and offers near-silent operation. This design reduces maintenance requirements while providing uninterrupted gas detection up to 20 meters.
Quick Specs
- Sentinel+™ Addressable technology
- Auto zero function for increased stability
- Low maintenance due to virtually no moving parts
- Up to 20M sample line
- Near continuous detection
- 1 L/Min sample rate
- Excellent zero stability = allowing lower more stable alarm thresholds
- Constant flow monitoring
The TOC-750S sampled fixed gas detector features automatic zeroing (Auto Zero) and automatic calibration (Auto Calibrate). The zero port of the 750 series sampling unit is equipped with active filtration, and the system automatically performs periodic zeroing; in the case of oxygen measurement, it automatically calibrates itself.
This feature provides superior zero stability for the sensor, allowing alarm levels to be safely set lower than the sensor’s measurement range. For example, while an ammonia detection measurement range of 0–1000 ppm is offered, exposure monitoring and facility shutdown requirements under EN 378 can be fully met with alarm levels of 25 ppm, 35 ppm, and 500 ppm.
