Overview
The CVS4200C is a composite, stationary water sampler designed for indoor use. All samples are combined into a single container. The sampler uses reliable, long-lasting, vacuum technology. This sampling method results in faster sample draws and less disturbance of the sample contents. There is also less wear on the tubing, resulting in less frequent maintenance.
The CVS4200D differs from the CS4200C in that it is a discrete sampler that places each sample into a separate container.
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

Vacuum technology for better samples
Technical Description
The CVS4200C is an indoor stationary water sampler that deposits its water samples into one container. It uses an external vacuum pump to draw water through intake tubing, instead of the traditional peristaltic pump that induces flow by squeezing flexible tubing.
Advantages of the vacuum pump method include faster sampling rates, better vertical lifts, 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 controller that comes with the CVS4200C can accept a pulse input (for example, from a rain gage), a 4 to 20 mA signal (such as from a flow meter), or initiate a sample on a timed basis. The sampler can also be interfaced with our data loggers. Our data loggers can measure nearly any turbidity, water level, or hydrometeorological sensor, as well as control the sampler based on time, event, or measured conditions.
