Vacuum Pump
The PVS4100C and PVS4100D samplers use an external vacuum
pump to draw water through intake tubing, instead of the tra-
ditional 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:

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.
