The BVS4300C is a composite, stationary water sampler designed to handle your extreme outdoor environments. All of your samples are deposited into a single container. The sampler is housed in a corrosion-resistant steel enclosure with a locking door and bolted-down instrument panel.
The BVS4300C uses reliable, long-lasting, vacuum technology to draw water through its intake tubing. 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.
Vacuum technology benefits over peristaltic pump samplers:
The BVS4300D is similar to the BVS4300C, but it is a discrete sampler that deposits its samples into multiple containers.Read More
The BVS4300C uses an external vacuum pump to draw water through intake tubing, instead of the traditional peristaltic pump that induces 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.
The BVS4300C includes a programmable controller with 16-key intuitive touchpad. The controller can accept a pulse input (such as from a rain gage) or a 4 to 20 mA signal (such as from a flow meter), or the controller can 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 hydrometeorologic sensor, as well as control the sampler based on time, event, or measured conditions.
