Sentry HRX Automatic Strip Sampler

Part #
Sentry HRX

The Sentry HRX automatic hygienic strip sampler automates sampling of dry free-flowing materials such as granules, powders, flakes, pellets, grain or seed from positive or negative pressure systems, gravity chutes and hoppers. A strip sampler captures a sample strip across the diameter of a process stream, and is used in situations where material segregation exists.

Ideal for low moisture food production facilities that have high/medium hygiene classification zones and products that are sensitive to contamination and threats to food safety.

The Sentry HRX sampler combines proven representative sampling technology with a sanitary, fast-clean design that nearly eliminates the potential for bacterial build up. With representative sampling, characteristics of each sample match that of the entire lot or batch—so samples are repeatable, leading to accurate sample analysis data. Automatic sampling ensures a sample can be easily and safely obtained with no need for direct human interface or interference. This ensures sample integrity as well as operator safety.
