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 and store and logg values for later retrieval.

Through the use of USB and the free software SwemaTerminal 3 the stored values can be transferred to PC.


Measurement Range
CO2: 0...5000 ppm
Barometer: 600...1200 hPa

Measurement Uncertainty
1 minute after start:
CO2: ±35 ppm ± 3,7 % read value
Barometer:± 3,5 hPa

Measurement uncertainty with 95% coverage probaility in non condensating air.
in relative humidity below 80 %, at 0...35°C,
in relative humidity below 70 %, at 35...50°C, non aggressive gases

Sampling Interval
CO2: 16 seconds
Barometer: Twice per second

Display Interval
CO2: 16 seconds for the measured value
Two prognostications in between, indicated by a * on display. In stable conditions prognostications equal measured value.
Barometer: Twice per second

Log Interval: 16 seconds - 2 hours. Pump can be set on or off. Setting pump on turns it on 30 seconds before measurement is made.

Memory: 50 series of measurements, max 15700 measurement pairs all series combined. (CO2 and air pressure is a measurement pair)

PC Communication: Mini USB

Lithium-Ion Battery: Almost one week up time without pump and backlight (150 hours, 24 hours with backlight and pump)
USB charger and USB cable included

Delivery contents
Instrument, rechargeable battery, USB cable, 220V adapter, manual, calibration certificate.
