New technology for measuring ammonia gas
Sensor based on thin film polymer technology is highly selective to ammonia and has a long lifetime, reducing false alarms and maintenance costs
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 six hour drift less than 1ppm outdoors.
The warm-up time is short.
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. Request a free brochure from Vaisala ...
