Page 11: Introduction
CVS4200 / BVS4300 Stationary Samplers 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. -
