Accurate Monitoring of C02 is Vital Across Many Different Industries. Rely on Polestar For Precise Measurements.
Reliable, Accurate, and Maintenance-free Sensing
Polestar offers two types of CO2 sensing film – colorimetric and ratiometric fluorescence.
The colorimetric sensing film, originally developed for gas phase monitoring of conditions within rebreather dive gear, is specifically designed to detect at levels where CO2 is hazardous to human health.
The ratiometric fluorescence-based sensing film is designed for monitoring over a wider range of CO2 partial pressures for applications such as bioprocess monitoring. Detection involves direct reaction of CO2 with the hydrophobic polymer encapsulated indicator of the sensing film, eliminating the need for the bicarbonate buffer used in Severinghaus type CO2 sensors and the problems that can arise with large osmotic gradients.
Available ranges of operation
Colorimetric CO2 – 0 to 25 mbar
Fluorescent CO2 – 0 to 80% (1 ATM)
