This ECO2FluX gas flux measurement chamber sets new standards for measuring CO2 dynamics at the ecosystem level.
Because the chamber can be transparent as well as darkened, both Net Ecosystem Exchange (NEE) and Ecosystem Respiration (ER) can be measured directly and Gross Ecosystem Photosynthesis (GEP) can be estimated by their difference (GEP = NEE – ER), thus producing direct data of the processes behind NEE.
The chamber covers a ground area of 3,100 cm2 and has a volume of 220 L (at standard height of 80 cm) and is therefore big enough to include plants communities in many natural low-stature ecosystem types as well as many agricultural crops.

Portable vacuum pump
The portable vacuum pump is developed for the PRENART field equipment for soil and groundwater investegations. Due to it's simple construction and robustness, it is applicable everywhere when easy and quick access to vacuum or compressed air is required..

Soil water samlers
PRENART soil water samplers (suction cup lysimeters / Ger.: Saugkerze) are made of porous PTFE (teflon) mixed with silica flour or stainless steel powder.
