The Vaisala CARBOCAP® Carbon Dioxide Probe GMP343 is a compact field instrument designed for soil respiration measurements, other ecological measurements and various custom applications.
The metal-cased GMP343 operates in harsh conditions: in temperatures -40...+60 °C (-40...+140 °F) and humidity 0...100 %RH. The GMP343 weighs less than 0.4 kg and consumes under 1 W of power. The probe uses the unique Vaisala CARBOCAP® silicon-based infrared sensor.
The diffusion-aspirated design eliminates the need for sampling systems and pumps. In soil respiration box measurements this design also eliminates errors caused by pressure differences often present in pump-aspirated measurement systems. The GMP343 is very stable, with 6 hour drift less than 1 ppm outdoors, and has as a short warm-up time.
The GMP343 can output numerically filtered or raw measurement data. Additional features include heated optics, compensation possibilities for temperature, relative humidity and pressure, and built-in self-diagnostics. In addition to the diffusion-aspirated version, the GMP343 is available as a flow-through version. The GMP343 can be powered and used with the portable MI70 indicator for convenient field measurement.

There are no moving parts within the sensors. An internal temperature sensor is included to enable the temperature to be monitored at the detectors, thereby providing the best means of compensating for temperature effects, including ideal gas law corrections.
CO2 Gas Ranges
IR-CO2-A1 Carbon Dioxide 0 to 5,000-ppm
IR-CO2-AH Carbon Dioxide 0 to 5% Volume
IR-CO2-AE Carbon Dioxide 0 to 20% Volume
IR-CO2-AS Carbon Dioxide 0 to 100% Volume
Sensor Interface
In order to derive a signal from the Alphasense infa-red sensors, the lamp should be pulsed at a constant frequency and duty cycle and power should be applied to the on-chip FET transistors. The signal can then be extracted from the on-chip FET transistor sources and the internal sensor temperature can also be monitored continuously. |
