Geotech Auto Sampler

Automatic Peristaltic Sampling Pump

The Geotech Auto Sampler automatically collects numerous individual discrete samples taken at regular intervals over a period of time. The flow-weighted sample collected is representative of an average concentration of any substance being analyzed. Designed for portable or dedicated applications, the Geotech Auto Sampler is effective in outfall, in-stream, manhole, and open-fluid sample point applications.
