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 alarm 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
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/alarm 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.
