The Efcon Peristaltic Sampler is equipped with reliable basic hardware and standard electronics.
Although the design is aimed at long-term reliable sampling with minimal downtime, the maintenance frequency in permanent use is definitely higher than with a vacuum sampler. The peristaltic sampler can take samples from a well and/or channel and has a 9 mm diameter hose.
Mount the end (inlet) of the suction hose at a fixed representative point to sample homogeneous wastewater. Ensure that the suction hose always exits into the wastewater / medium and that the opening is not blocked.
Caution! Not allowed for billing in the Netherlands!
A peristaltic sampler needs regular cleaning of the sample hose and water level detector.
The contact level indicator operates at a minimum wastewater conductivity of 50 µs. When conductivity drops too deeply (in the case of demi or pure rainwater), an optional capacity switch can be added to create a fully functioning level detection system.
