diffusion ventilation---------No gas sampling system required

The concept of the product is to eliminate the bulky and power consuming sampling system. Its power consumption is very low or even less than1Wa.

Innovative solution for soil respiration measurement

Using diffusion ventilation to eliminate errors caused by pressure differences in pump sampling

Sturdy metal structure

GMP343The structure isIP67Suitable for harsh environments. The diaphragm filter of the probe blocks dirt and dust. Heating the optical part can prevent the formation of condensation.

User configurable measurements

GMP343The output can be either numerical filtering or outputting raw data. Internal compensation may also be performed if we have built-in temperature probes or user set relative humidity, air pressure, and oxygen values.

calibration

GMP343use0.5%Gas calibration and linearization. If users need to calibrate themselves, using multi-point calibration performance allows users to set10A benchmark point.

GMP343It is an ideal measuring instrument for soil respiration chambers. The diffusion ventilation design eliminates errors in sampling systems and pressure differentials caused by pumps.
