The SRF high-end automatic sampler can be used for taking representative samples of powders, granules or flakes out of down spouts and hoppers. Due to the use of a screw, also poorly flowing products are easy to process. The outer tube can be equipped with a connection piece or directly welded into the hopper. 

Due to its accurate finishing, this sampler is very suitable for high-end applications in the food and dairy industries. The SRF is internally ATEX 2014/34/EU certified, external ATEX 2014/34/EU certified is optional.

The sample size is adjustable. By starting the sequence with an external signal, the auger will first turn backwards for an adjustable period of time to remove possible sample material from the previous taken sample. Afterwards it takes the actual sample during an adjustable period of time, depending on the required size of the sample.
