The EcoLab Master Control SSA is a device that allows simultaneous soil water sampling for several Ecotrons. In addition, it is possible to select and individually operate individual Ecotrons with the device. The EcoLab Master Control SSA is therefore ideal for research facilities that have systems with multiple ecotrons to be controlled. The connected ecotrons can be operated easily and time-saving via a touch screen.

For soil water sampling, negative pressure is generated for up to three different lysimeter depths by means of three vacuum circuits. Each vacuum circuit is equipped with a vacuum pump and a buffer tank. The vacuum set on the unit is transferred to all connected Ecotrons by means of a ring line. If the soil entension varies greatly between the individual Ecotrons, the vacuum should only ever be applied to Ecotrons with similar soil entension. All other ecotrons will not be activated. The prevailing soil entension in the individual ecotrons can be read out via the touchscreen of the EcoLab Master Control SSA.
