ProSample Automated Sampler

The ProSample series of fully automated samplers expands the YSI offering in wastewater, stormwater and industrial wastewater markets as well as others. With two portable options, the ProSample P and the ProSample PM, that are designed to be user friendly and easy to program, the ProSample series provides reliable data to keep your facility in compliance with regulations.

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.

Programming the ProSample series is quick and user friendly. Calibration time takes less than 2 minutes and can be done on the sampler itself or on PC with downloaded YSIConnect software. Once the sampler is ready for operation, a light will flash green as a visual indication the sampler is properly programmed and calibrated and ready to begin service.

Sampling based on time, flow or event are easily programmable on the ProSample keypad. The automated sampler is battery operated and has extended battery life. The sampler will get up to 550 samples from one battery charge.

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.

Accessories that increase the flexibility and enhance the product include, optional bottles* (number and size), a suspension harness, filter basket,  and transport trolley in addition to others.
