T-Sentry 140-200RB Product Overview:

The Model T Sentry 140-200RB is a NIST calibrated/traceable single probe ultra low temperature (ULT) freezer monitoring and alert status indication system that utilizes a type "T" thermocouple embedded in a 3.0-inch long stainless steel sheath. This particular configuration of probe and monitor is excellent for accurately measuring the temperature (and/or level) of cryogenic liquid nitrogen (LN2) in freezers and other cryogenic cold storage vessels and systems.

This unit helps technicians maintain safe continuous cold-chain ultra low temperatures for cold storage of viruses, vaccines, IVF (in-vitro fertilization) materials, other biological materials, biopharma drugs and related applications.

This unit allows you to optionally upgrade (at any time) from "real-time" monitoring and alarm status indication to higher level Ethernet network data logging for compliance and/or SPC capability (together with our Model AMS data logger/alert notification system).

The T Sentry 140-200RB is a wall-mountable unit that's approximately 5" wide x 4.25" high x 1.75 deep which uses a small plug-in power supply for operation.

NOTE: The system can be used in a "stand-alone" mode or optionally integrated into our AMS remote PC-based, Ethernet network data logger/alert notification software. This configuration allows network-level data logging for documentation and SPC.
