Sentry ISOLOK MSA Automatic Sampler

Part #

The Sentry ISOLOK MSA automatic point sampler is designed for sampling sanitary products such as Grade A or industrial grade raw or processed milk. This sampler can be used in a process line or on the wall of a vessel or reactor. It can also be installed on road tankers transporting liquid milk. Users and university study data report typical butterfat tests within .02% of known values, with bacteria counts comparable to hand samples.

This sampler is conformant to 3-A Sanitary Standards (third-party verified) with a reliable, sanitary, easy-to-clean design with FDA-approved seals. The sampler is powered by compressed air and operated by an electrical cycle controller that provides adjustable, time-based sampling rates. The controller circuit has been designed to provide an adjustable time delay before the sampler begins operation. Other applications of this sampler include low-volume chemical sampling or biofuel/hydrocarbon sampling.
