The LogiCO2 Mk90 is the easiest and most cost effective way to detect and alert of dangerous CO2 leakages. It also inhibits lost revenue due to costly CO2 leaks. With easy installation, virtually zero maintenance and perfect functionality, the LogiCO2 Mk90 is the logical way of minimizing any CO2 risks for the working staff and customers 24/7.
The Mk90 CO2 Sensor is a Stand-Alone system that can be connected with the Mk9 Central Unit and Mk9 CO2 Sensor Set.
It is a CO2 monitor with integrated sound and light alarm indication, designed to measure CO2 concentration in a confined space environment. It provides an alarm in the event that a CO2 level considered unhealthy/dangerous is reached, in accordance with existing safety codes, in the area being monitored.
Translucent enclosure and functional design with high intensity red alarm LEDs are some of the features of the MK90 CO2 Sensor. 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 Mk90 CO2 Sensor with display, a Horn/strobe, cabling and signage. The Mk90 CO2 Stand-Alone SET, provides 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.
The default alarm levels are:
– 5000 ppm Awareness Alert
– 5000 ppm TWA 8Hr (PEL)
– 1,5% (15.000 ppm) ½ STEL
– 3,0% (30.000 ppm) STEL

Frequently asked questions
How is this stand-alone kit different from a system with a central unit?
The MK90 sensor combines CO2 measurement with its own sound and light alarm, so it works without a central unit. LogiCO2 states that the stand-alone sensor can also be connected with its central unit and sensor set.
Where should the sensor and the horn/strobe be 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 horn/strobe mounts 80 to 96 in (2 to 2.4 m) above the floor, clearly visible from any entrance.
Can it be used in a walk-in cooler?
LogiCO2 lists the sensor's operating range as 0 to +45°C (32 to 113°F), indoor use only, and the sensor has a temperature alarm that can be activated for cold room applications. Rooms that run below 0°C (32°F) are outside the listed range.
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.
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.
