SwemaCO2 is an accurate CO2 meter and logger from Swema that can measure at precise locations through the use of a hose and the built-in pump.
The pump also decreases the response time. A built in barometer is used for automatic pressure compensation. The instrument can show the average of multiple measurements. Together with the PC-program SwemaTerminal 3, SwemaCO2 can show saved measurements and show graphs of logged values.
