The Vaisala CARBOCAP
®
Carbon Dioxide Probe
GMP343 is an accurate and rugged probe-type
instrument for ecological measurements. Typical
applications include CO
2
soil respiration, ambient
CO
2
monitoring, plant growth chambers, and
OEM applications.
The GMP343 can output both numerically filtered
and raw measurement data and it can also
compensate the measurement with an internal
temperature measurement and user-set relative
humidity, pressure and oxygen values.
In combination with an MI70 indicator, the GMP343
provides a tool for accurate in-situ measurement.
The MI70 can be used as a display, communication
and data logging device.
Each GMP343 is calibrated using ±0.5 % accurate
gases at 0 ppm, 200 ppm, 370 ppm, 600 ppm,
1000 ppm, 4000 ppm and 2 %. Calibration is also
done at temperature points of -30 °C, 0 °C, 25 °C
and 50 °C. If needed, the customer can recalibrate
the instrument using the multipoint calibration
(MPC) feature allowing up to 8 user-defined
calibration points.
