Peristaltic Sampler
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.
- Before sampling, the peristaltic pump will blow the suction line clean to take as homogeneous a sample as possible and remove blockages.
- The peristaltic pump will change rotation direction and start sucking the sample up to the medium sensor. If no medium is measured, this will result in a false sample.
- After this, the pump rotates some more and the sample falls into the container.
- The direction of rotation changes and the pump will remove the excess medium.
Caution! Not allowed for billing in the Netherlands!
A peristaltic sampler needs regular cleaning of the sample hose and water level detector.
- Maximum suction height: 8 metres
- Maximum suction length: 30 metres
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.
Can peristaltic samplers be used for billing purposes in the Netherlands?
No. In the Netherlands, peristaltic samplers are not accepted by the regional water authorities for billing purposes. For this application, vacuum or in-line samplers are required.
What is the difference between a Jazz and a Vision controller?
The Jazz controller is simple to operate, with basic functions suitable for standard applications. The Vision controller features a larger display, more configuration options, and data logging capabilities, making it ideal for more complex applications.
