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.
