LogiCO2 Mk9 O2 sensor to extend or replace a detection point
The LogiCO2 Mk9 O2 sensor module is an optical oxygen sensor for systems with an Mk9 central unit. It measures ambient O2 concentration, displays the value on screen, and generates an alarm when the level drops below a safe threshold.
What this product offers
This product fits as a spare part or extension within an existing LogiCO2 system. It is not a complete kit with central unit, horn, or power supply, but the oxygen sensor module.
Its technical value lies in optical oxygen measurement with integrated temperature and pressure compensation, low power consumption and long service life. The manufacturer also states that it is factory-calibrated.
It is a useful solution in installations where it is necessary to monitor atmospheres with low-oxygen risk and keep the reading integrated within the LogiCO2 Mk9 ecosystem.

Compatibility and use cases
This sensor is designed to work with the LogiCO2 Mk9 control unit and communicate via Modbus RTU within the safety system.
The manufacturer states that it can be used together with the different LogiCO2 CO2 sensors, which makes it useful in mixed installations where different gas risks are monitored within the same architecture.
It is suitable as a replacement for an existing sensor or as an expansion of a compatible system, provided the configuration of the assembly and the corresponding wiring are respected.
Installation and considerations before buying
- Confirm before purchasing that your installation has a compatible LogiCO2 Mk9 central unit.
- Check whether you need only the sensor or also cabling, since the datasheet defines it as a spare part without cable.
- Check the reference of the sensor to be replaced to avoid errors during maintenance or expansion.
- If your system combines CO2 and O2 sensors, check the overall architecture before expanding.
- Al ser un componente de seguridad, la instalación y comprobación funcional deben realizarse con criterio técnico.
Recommended maintenance and use
As this is a safety sensor, it is advisable to periodically check its operating status, the display reading, LED indication, and audible fault or alarm warning.
After any replacement, it is advisable to verify proper communication with the Mk9 control unit and check that the reading and local signaling respond correctly.
