PSI CO2-ProTM

The PSI CO2-ProTM is a compact, light-weight, plug-n-play pCO2 sensor that is designed for use on moorings(to 1000m), on profilers, in under-way mode, and in thelaboratory. The PSI CO2-ProTM is fitted with an IRdetector and the new PSI pump-driven fast interface(patent pending). This revolutionary new interfaceprovides an equilibrated gas stream to the detector.

The PSI CO2-ProTM is factory calibrated from 0 – 600ppm with calibration burned into EPROM. To maintainaccuracy, the detector module has a power interrupt orcontact closure initiated automatic zero point calibration(AZPC). When the AZPC is initiated, the gas stream isrouted through a CO2 absorbent to provide a zero ppmCO2 measurement. The CO2 zero measurement com-pensates for changes in optical cell performance, and isused in determinations of ppm CO2 until a new AZPC isperformed.

Features:

- high precision and accuracy- low cost- light weight, compact size- unique antifouling protection- RS-232 data interface- data stream includes raw data and ppm CO2- power saving and onboard logging options available
