If there is CO2 in the gases it will turn the fluid green indicating a blown head gasket or similar issue.

A CO2 leak detector is a device designed to find CO2 gas leaks along various gas lines and connections. By utilizing an optical filter with precise characteristics, INFICON has made D-TEK CO2 sensitive to CO2 while minimizing false alarms. Signal Conversion: The infrared sensor measures the intensity of the light that has passed through the gas sample and converts it into an electrical signal. They help identify and locate potential CO2 leaks before they become a health hazard as CO2 can accumulate and deplete the oxygen in an indoor space. I have been designing, building, manufacturing, and testing toxic gas detection systems for over 20 years.The RELD tester is used to detect damage to the head and head gasket of liquid-cooled internal combustion engines (petrol, diesel, LPG). If you suspect a significant CO2 leak or are experiencing symptoms of carbon dioxide poisoning, evacuate the area and seek fresh air immediately. This makes it useful in a variety of applications and industries such as beverage, winemaking, breweries, or anywhere compressed CO2 is piped into a building.

Also with exclusive ergonomic design and innovated large TFT LCD display screen, the detector optimizes the user experience and presents the detection results more intuitively and diversely. It uses a CO2-specific infrared sensor, which has over 10 year's service life and high accuracy of 6g/year. Agricultural and horticultural settings: In certain agricultural practices, such as greenhouse cultivation or indoor farming, carbon dioxide is often supplemented to enhance plant growth. You can change your choices at any time by visiting Cookie preferences, as described in the Cookie notice.This helps maintain appropriate conditions and prevent the buildup of carbon dioxide in enclosed spaces. The lifespan of a CO2 (carbon dioxide) NDIR (Non-Dispersive Infrared) sensor last between 5 to 15 years.
