GEO ATMOS is an ideal instrument for the sampling of gaseous compounds in emission. It has a low-flow diaphragm pump electronically controlled and a volumetric meter with a minimum flow rate of 0.016 m3/h.

It is equipped with a temperature sensor (removable for calibration) and pressure sensor at the meter

The GEO TANDEM model is the “double” version of the GEO ATMOS sampler.

It includes 2 independent sampling lines with the special feature of having both meters on the front of the instrument. Both models can operate powered by mains supply or by internal rechargeable batteries.
