APS- Acid Precipitation Sampler

Designed as an Atmospheric Precipitation Sampler (A.P.S.) for accurately separating and collecting both total precipitation and total particulate deposition for later laboratory analysis of pH, conductivity, and specification.

Specifications:
  • A recording elapsed time indicated is included as standard equipment.
  • An on/off indicator light is provided for visual inspection.
  • A cycle counter designed to record the number of open/close cycles during any time period.
  • A rugged sensor detects precipitation episodes and activates the cover drive to seal the dry deposition collector and expose the wet precipitation collector
  • The control consists of high input impedance schmidt trigger and a relay driver.
  • The drive system consists of a motorized ball screw actuator, a four-bar linkage and two limit switches.
  • The collectors segregate dry and wet samples.
