The Model T Sentry Model 140 is a user-programmable, computerized temperature alarm monitoring system that can be configured to operate in temperature ranges from-200 to +400 degrees C. This compact, yet powerful system is available in a wall-mount or free-standing
configuration, includes high / low temperature alarms, audible and visual alarm indication (via beeper and LED),
settable mute, and alarm "chirp" periods, and a UL-listed plug-in power supply. Other features
include alarm beeper muting (with user-selectable
periods; up to 30 minutes, optional relay contacts (for indicating a freezer temperature
alarm condition / power failure) and the ability to hook into a remote
alarm or telephone dialer. Customized programming is easily accomplished for any temperature alarm monitoring requirement (see video below).
This alarm/monitoring system is most often used within freezers, refrigerators, and coolers as well as within environmental chambers. It can also be used in to monitor processing and storage conditions in heating chambers, conveyorized ovens and batch ovens.
