- 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
- 1 double contact 24 VDC level detector with alarm output
Contact level indicator functions on a minimum wastewater conductivety of 50 m/s. When the conductivety 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.
Note!
A vacuum sampler need regular cleaning of the sampling head.
