CVS4200 / BVS4300 Stationary
Samplers
1. Introduction
The CVS4200-series and BVS4300-series Stationary Samplers are automatic
liquid samplers for water and wastewater applications. They use 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.
Campbell Scientific offers the following stationary samplers:
• CVS4200C—composite indoor sampler
• CVS4200D—discrete indoor sampler
• BVS4300C—composite outdoor sampler
• BVS4300D—discrete outdoor sampler
Composite samplers deposit all samples into a single container. Discrete
samplers place each sample into a separate container.
Before installing the water sampler, please study:
• Section 2, Cautionary Statements
• Section 3, Initial Inspection
• Section 4, Quickstart
2. Cautionary Statements
• A noise free or clean line from primary power is highly recommended to
supply the sampler.
• Never run the sampler’s power wiring in conduit containing phone lines or
power wiring of other devices.
• If possible, site the sampler away from ac power lines.
• Use a BVS4300 with a factory installed heater (option -H) and an
insulated cabinet (option -3) if the sampler will be located outdoors in
freezing conditions. Refer to Section 7.1, Use in Adverse Conditions, for
more information.
• In extreme cold conditions, insulate or heat the intake hose. If the hose is
positioned mostly vertical, the most prone point of freezing is where the
hose enters the frozen water source.
• Use a BVS4300 with the cabinet circulation fan (option -G) if the sampler
will be placed directly in the sun. This keeps the refrigeration unit from
getting overtaxed.
