T Sentry Model 140 systems are ideal for single sensor probe alarm, monitoring and quality documentation needed in cold storage applications - such as when storing "condition-sensitive" items in refrigerators, freezers and coolers. The standard unit operates in temperature ranging from -200 to +400 degrees C. It includes settable high / low temperature alarms, audible/visual alarm indication (via beeper/LED),
programmable alarm mute and "chirp" periods, and a UL-listed plug-in power supply.
Other key features
include alarm muting for user-selectable
periods (up to 32 minutes), optional relay contacts (for indicating a freezer temperature
alarm condition and/or power failure) and the ability to hook into an optional alarm auto dialing system. Best of all, setup is easily accomplished for your requirements (watch the video below and see how it works for yourself).
This alarm/monitoring system is most often used within laboratory and hospital freezers, refrigerators, and coolers as well as inside environmental chambers. It can also be configured to monitor the processing and storage conditions inside of heating chambers, conveyorized ovens, and more.
NOTE 2: The T Sentry 140 and all MPS Series Systems have been engineered to easily operate together with our "Alert Monitoring System" wireless data logger. Consult us if you intend to use your new or existing products in this manner.
