LogiCO2 Mk9 CO2 Detector Base Set
LogiCO2 Mk9 CO2 Detector Base Set
- Measurement Range: Monitors real-time CO2 concentrations from 0.0% to 6.7%.
- Multi-Data Display: Digital interface alternates between actual CO2 %, Time Weighted Average (TWA) in ppm, and ambient temperature (°C/°F).
- System Scalability: Central Unit supports the integration of up to twelve (12) independent Mk9 sensors for multi-zone monitoring.
- Calibration: Features factory-standard automatic self-calibration for long-term sensor accuracy and reduced maintenance.
- Field-Adjustable Alarms: User-configurable alarm set-points to ensure compliance with localized safety codes, OSHA, and EH40 legislation.
- Output Components: Includes high-decibel acoustical horn and high-visibility optical strobe for immediate hazard notification.
- Interface Type: Plug-and-play architecture utilizing pre-terminated cabling for rapid field deployment.
- Legacy Compatibility: Official successor/replacement for the LogiCO2 MkVII CO2 Sensor System.

The Mk9 CO2 sensor is the latest generation of CO2 Safety Systems and has replaced the LogiCO2 MkVII CO2 Sensor System. A large display, functional design and revolutionary language functionalities are some of the new features of the MK9 CO2 Safety System. The display alternates between actual CO2 concentration (0.0%- 6,7%), TWA (ppm) and temperature (°C or°F), (if temperature alarm is activated for cold room applications).
This complete plug and play SET contains a Mk9 CO2 Sensor with display, a Mk9 Central Unit to display the measured values, a Horn/strobe, cabling and signage. Up to twelve sensors can be connected to the Mk9 CO2 Safety Detector SET, providing a sophisticated and powerful CO2 Safety System while still being the most economical and easiest system on the market. All LogiCO2 sensors have automatically calibration as standard. The alarm levels can be changed to any level to comply with all local Safety Codes and legislation.

Frequently asked questions
How many sensors can one Mk9 Central Unit monitor?
Up to twelve. The base set includes one Mk9 sensor, and LogiCO2 states that up to twelve sensors can be connected to the central unit.
Where do the sensor, central unit and horn/strobe get mounted?
LogiCO2's manual puts the sensor no more than 12 in (30 cm) above the floor and within 5 m (16.4 ft) of the CO2 distribution point. The central unit goes outside the monitored area at a visible, reachable height, and the horn/strobe mounts on the wall above the sensor, 80 to 96 in (2 to 2.4 m) above the floor. The manual also calls for a second horn/strobe outside the monitored area, preferably over the door; this set includes one.
What are the factory alarm levels, and can they be changed?
The defaults are a 5,000 ppm awareness alert, a 5,000 ppm 8-hour TWA alarm, a 1.5% low alarm and a 3.0% high alarm. LogiCO2 states the levels can be changed to comply with local safety codes.
What power does the system need?
The set runs from the supplied plug-in power supply: 100-240 V AC, 50/60 Hz input and 24 V DC, 1.0 A output, with interchangeable mains plugs. LogiCO2's manual notes that a hardwired power supply exists as a separate option where one is required.
Does the sensor need calibration or regular testing?
The sensor has an automatic self-calibration feature. LogiCO2 recommends that a qualified service agent carry out a function check of the system at least once a year.
