The PVS4120C is a lightweight, portable, battery-operated water sampler that deposits its water samples into one container. It includes 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. The sampler can also be interfaced with our dataloggers to measure a variety of sensors, as well as control the sampler based on time, event, or measured conditions.

Benefits and Features

  • Lightest composite sampler offered by Campbell Scientific—weighing only 12 kg
  • 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
  • Side handles for easy lifting (increases diameter)
  • Handcart available for easy transport
  • Stainless-steel suspension harness offered for sampling in sewer systems
  • Interfaces with Campbell Scientific dataloggers for more measurement and control capabilities
