If you need a sample cooler or sampling equipment for steam/water, gases, liquids, slurries or bulk solids, you have come to the right place. Sentry has over 80 years experience in manufacturing sampling components and sampling systems. Hobré Instruments is the Sentry representive for over 25 years in the Benelux. Sentry also manufacture compact heat exchangers and boiler blowdown heat recovery systems.

Bulk Solids & Liquid Sampling
The ISOLOK® Series Bulk Solids and Liquid Samplers provide a simple, reliable means of collecting representative samples. An air cylinder extends a single plunger into the process material, then immediately withdraws, carrying a fixed amount of sample trapped in an annular ring between plunger seals. Process or flow ports are always closed, preventing leaks or product loss. There are no tubes or passages to become clogged. The gravity-discharged sample is transferred directly to a closed container. Sample integrity is maintained while contamination of personnel or facility is eliminated.

A complete line of programmable automatic controls is available for use in general purpose as well as hazardous environments.

Gaseous & 2-Phase Sampling
Closed loop cylinder sampling is the most effective way to take and transport gaseous or 2-phase liquid samples. By purging the sample path and the sample panel during each sample cycle, representative sample is assured within the cylinder. As well, purging of the sample panel after the sample is secured provides for maximum operator safety and minimum loss of sample vapors to the environment.
