The PVS4100D is a deluxe portable, battery-operated water sampler that deposits its water samples into 24 containers. It uses our biggest sampler pump allowing it to support the fastest sampling rates and longest sampling distances. The PVS4100D includes a programmable controller with 16-key intuitive touch pad. The controller can accept a pulse input (e.g., rain gage), a 4- to 20-mA signal (e.g., flow meter), or initiate a sample on a timed basis. The sampler can also be interfaced with our dataloggers to measure a variety of sensors, as well as control the sampler based on time, event, or measured conditions.
PVS4100D Benefits
Bigger pump allows it to support faster sampling rates and longer sampling distances
Vacuum technology benefits over peristaltic pump samplers:
Accurate sample volumes
Rapid transport velocities mean more-representative samples
Less disturbance of sample
Minimal wear on the tubing, resulting in less-frequent maintenance
Reduced cross-sample contamination
Side handles for easy lifting (increases diameter)
Handcart available for easy transport
Stainless-steel suspension harness offered for sampling in sewer systems
Interfaces with Campbell Scientific dataloggers for more measurement and control capabilities
Technical Description
The PVS4100D uses an external vacuum pump to draw water through intake tubing, instead of the traditional peristaltic pump that induce flow by squeezing flexible tubing. Advantages of the vacuum pump method include faster sampling rates, longer sampling distances, and less maintenance. Because the vacuum method disturbs the water samples less, they better represent the original water solution, especially if the solution has high concentrations of suspended solids. To prevent cross contamination, the sampler use air pressure (up to 28 psi) to purge the tubing of excess water.
The enclosure of the PVS4100D is a molded medium-density linear polyethylene, designed to handle tough environmental challenges and weathering. Its hub has an insulated ring and a cavity for crushed ice, giving more control over the temperature of the sample.
