International Gas Detectors’ TOCSIN 750S aspirated gas detector is an addressable aspirated gas detector that enables users to offer gas detection in areas otherwise hard to approach or harmful for normal diffusion sensors.
Featuring the special piezo pump technology, International Gas Detectors’ aspirated gas detectors have practically no moving parts and are quiet in operation, decreasing maintenance need and offering almost constant gas detection up to 20 m away.
- Oxygen (O2): 0% to 25% VOL
- Hydrogen (H2): 0 to1000 ppm
- Formaldehyde (CH2O): 0 to 5 ppm
- Flammable (FLAM): 0% to 100% LEL
- Carbon monoxide (CO): 0 to 100 ppm
- Volatile organic compounds (VOC): 0 to 200 ppm

The 750S aspirated gas detector makes use of the revolutionary Sentinel+ addressable communication protocol. Gas sampling systems have been utilized for areas where there is a necessity for remote detection. Examples include clean rooms, difficult to access areas, bore holes or height restrictions and extreme temperatures.
Piezo Pump Technology
In addition, the 750S aspirated gas detectors include the piezo pump technology from International Gas Detectors. This technology offers the samplers with practically no moving parts, valves, or pump seals. This decreases its maintenance costs and improves its reliability.
Auto Zero Function
The TOCSIN 750S aspirated gas detector includes industry-leading auto-calibrate or auto-zero feature. The 750 samplers zero port features active filtration and the system automatically becomes zero periodically, or in the case of oxygen detection, it calibrates itself.
This offers unprecedented zero stable for the sensor, thereby enabling users to have low alarm levels in comparison to the sensor range like N2O gas. For oxygen detectors, this indicates that the 750 samplers can calibrate themselves.
Sentinel+ Technology—2-Wire Addressable Technology:
Similar to all 2-Wire Addressable detectors, the 750S aspirated gas detectors make use of the industry-leading and revolutionary Sentinel+ technology from International Gas Detectors. All detectors are connected through a daisy-chained two-core cable that helps to decrease installation charges significantly by 70% to 80%. The cable avoids the need for polarity, thus making the installation much quicker compared to traditional systems.
The Sentinel+ technology offers power and communication to all connected devices with the help of only this two-core cable. The system offers a complete range of reporting features. Every sensor points out in real time digital values each second, offering improved safety by constant self-monitoring.
