CO2-Pro™ CV Atmosphere Air-Water pCO2 Sensor
The CO2-Pro™ CV Atmosphere is designed to measure both water-side and air-side carbon dioxide, making it an ideal solution for monitoring CO2 flux at the air-water interface. Standard ranges from 0-600 ppm up to 0-10,000 ppm as well as custom ranges are available.
A combination of the industry-leading CO2-Pro™ CV sensor and an air-side sampling unit (NEMA box or AirBall), the CO2-Pro™ CV ATM is the sensor of choice for most carbon flux measurement applications. The instrument is well-suited for integration into autonomous surface platforms and shipboard flow-through systems.
The small size of the CO2-Pro™ CV ATM means it is easily transported and deployed in the field. An internal zeroing feature provides a stable long-term baseline to ensure accurate measurements. The CO2-Pro™ CV ATM is factory calibrated using WMO traceable standard gases. In addition, detector temperature stabilization and measurement of gas stream pressure and humidity provide accuracy unparalleled by other small submersible pCO2 instruments.
