Sentro 1
Universal gas detector.
Sentro 1 is a fixed universal gas detector designed for mining and tunneling environments. At the heart of Sentro 1 is the eModule; intelligent standardized gas sensing modules to cover a range of toxic and flammable gases.
- High accuracy gas detector with calibrated input sensing emodules
- Automatic calculation of STEL and TWA limits
- Auto ZERO and SPAN calibration with simple display instructions
- Two programmable setpoints for inbuilt visual alarms
- Change eModule in seconds for easy calibration and maintenance
Features
Multiple Gases and Ranges
eModules are available in a variety of different gas sensing ranges of toxic and flammable gases.
Pre-Calibrated
High accuracy gas detector with calibrated input sensing modules to detect a different ranges.
Plug-and-Play
Service, calibration, or switching to a different gas, only requires the change-out of the eModule and can be done with the power still applied.
Data Logging
Each module contains data logging that can be networked to a PC for central control and monitoring and is fully addressable from the base station.

Universal Gas Detection
The heart of Sentro 1 is the eModule; an intelligent standardised gas sensing module to cover a range of toxic and flammable gases. Dynamic data is stored within each module, together with the condition of the gas sensing element and its service history.
The modules are already calibrated so they can be used substituted at any time with replacement module. Each eModule retains its calibration data and is automatically recognised by Sentro when the eModule is inserted. This significantly simplifies calibration and maintenance and the module can be changed, even with the power applied. Up to 20 insert codes can be configured when it is necessary to ensure that the same type of Sentro eModule is always used.
