l AP200System Overview

The AP200 system developed by CSI in the United States is mainly used to measure the concentration profiles of CO2 and H2O in the atmosphere. It is a comprehensive measurement system for monitoring the changes in CO2 and H2O content on vertical profiles, measuring the spatial distribution and transmission patterns of CO2 and H2O. AP200 can measure the concentrations of multiple layers of CO2 and H2O, with up to 8 profiles in conventional designs. It is typically used in conjunction with vortex related systems for more systematic measurements of atmospheric surface gas exchange.

l AP200System features

Low energy consumption, only requiring a 13W power supply (under the conditions of an average temperature of 25 ° C and a 12V DC power supply)

The system adopts CR1000 data collector

Automatic calibration of standard gas, completing zero and span value calibration

Automatically control the internal pressure and temperature of the analyzer to reduce measurement drift errors

Pre installed measurement and control programs inside the data collector
