PVS4100D
Overview
The PVS4100C and PVS4100D are deluxe, portable water samplers that use ac power with a backup battery. The PVS4100C is a composite sampler that deposits its water samples into a 9 L bottle; the PVS4100D is a discrete sampler that deposits its water samples into up to 24 containers. These samplers have a bigger pump than our other portable water samplers allowing them to support the fastest sampling rates and longest sampling distances.
Benefits and Features
Rapid transport velocities of samples (horizontal draws 76.2 m
(250 ft) at 0.8 m s -1 (2.5 ft s -1 ), meaning more accurate samples, even of solids
Controller housed in an environmentally sealed enclosure for corrosion protection, and all information is easily controlled and viewable on a 2 by 16 character backlit LCD
Composite or discrete models available
Side handles for easy lifting (increases diameter)
Interfaces with Campbell Scientific dataloggers for more measurement and control capabilities
Stainless-steel suspension harness* available for sampling in sewer systems
Handcart* available for easy transport
Options*
Quick connect terminals
Power supply options: 80 to 264 Vac with a 17 A h battery or
80 to 264 Vac without a battery
Water Detection Probe
Warranty options: three or five year
Sample container options: no bottles, 9 L bottle (PVS4100C only), 24 0.5 L bottles (PVS4100D only), or 24 1 L bottles
(PVS4100D only)
PVS4100C size options: 3/8 in. ID system or 5/8 in. ID system
(the PVS4100D Discrete Sampler is a 3/8 in. ID system only)

Technical Details
Vacuum Pump
The PVS4100C and PVS4100D samplers use an external vacuum pump to draw water through intake tubing, instead of the traditional peristaltic pump that induce flow by squeezing flexible tubing. 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 samplers use air pressure (up to 28 psi) to purge the tubing of excess water. See our vacuum pump water samplers in action at: www.youtube.com/watch?v=wi4dxFTw-ks
Controller/Interfacing with a Datalogger
The PVS4100C and PVS4100D include 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. See a demonstration of the programmable controller at: www.youtube.com/watch?v=yRr80Lm-5Hs
The sampler can also be interfaced with our dataloggers. Our dataloggers can measure nearly any turbidity, water level, or hydrometeorologic sensor, as well as control the sampler based on time, event, or measured conditions.
