Vacuum Samplers are equipped with reliable basic hardware and standard electronics. The complete design is focused on long term reliable sampling with minimum drop out.
The Vacuum Samplers are build up with 1 sampling head with a glass or non breakable polycarbonate chamber, 1 bi-directional 24 VDC airpump (in 2 different capacities), 1 bi-directional 24 VDC pincher and 1 double contact 24 VDC level detector with alarm output.
Contact level indicator functions on a minimum wastewater conductivity of 50 m/s. In case conductivity drops to deep (in case of demi or pure rain water), an optional capacity switch can be added to create a full functioning level detection system.
