The ProSample series has extremely high volume accuracy to keep your facility in compliance. The ProSample series is most commonly used in stormwater and storm event sampling, influent and effluent wastewater treatment, collection systems for industrial pre-treatment and any time based sampling requirements. The ProSample series provides a unique combination of design and technology.

The proprietary peristaltic pump supplied with the ProSample series, allows for accurate sampling volumes, by using a two sensor design versus the more common one sensor design of most buy-out peristaltic pumps. The samplers come with two sets of tubing, one for operation and one as a spare as standard. The spring loaded roller bearings of the pump provide longer tube life, up to 20% longer than the competition.

Once taking samples and collecting data, the data log is easily recovered using a USB which than can be loaded into a PC. The ProSample series does not require a lap top to be brought to the sampler. The ProSample series has non-volatile data memory for up to 5 years, so you never have to worry your data is unable to be recovered if power is lost.
