Overview

The AP200 is a complete, integrated CO₂ and H₂O atmospheric profile system. It measures carbon dioxide (CO₂) and water vapor (H₂O) concentration from up to eight intakes, which are normally spaced along the height of a tower to give a vertical profile. The AP200 is often used in conjunction with an eddy-covariance system to measure the storage term and provide you with a more complete measure of the surface gas exchange.

Key Advantages

Complete, Integrated System
Preprogrammed and low power
