SENTRY MCG is a manual gas sample station that takes a gas sample from the process line into a sample cylinder in a closed system, with leak tightness and operator safety. It is used at refineries, petrochemical and natural gas plants to take representative gas samples for laboratory analysis. The panel carries isolation valves, a check valve, two pressure gauges and a sequential switching valve.

The standard configuration uses a 500 cc TPED-certified sample cylinder, Swagelok QC4 quick connects and a 3/4" Class 300 RF flange. There are also labeled station versions such as Sample Station MCG-1 and MCG-3, and special versions with an integrated cooler (e.g. TLR-4225U).
