TE-78-100 APS Atmospheric Precipitation Sample, Acid Precipitation Sampler |
|
|
|
Designed as an Atmospheric Precipitation Sample, Acid Precipitation Sampler for accurately separating and collecting both total precipitation and total particulate deposition for later laboratory analysis of pH, conductivity, and specification.
The Model A.P.S. is designed for severe environments with a main frame constructed of heavy gauge aluminum and powder coated, and holds two symmetrically placed collections. The collectors have a common garbled-roof cover with international sealing surface.
The TE-78-100 APS is designed to collect precipitation in two containers – one container is open only during precipitation and the other container remains open between precipitation events. This allows dry deposited material to be collected also. A specially designed sensor detects precipitation and activates the motor, which in turn transfers the cover from the wet container to the dry container. When the precipitation event is over the cycle is reversed. The most outstanding feature of this unit is the simplicity of design, reliability of the operating components, and the quality of the materials. |
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. |
