The T Sentry Model 140 is a stand-alone single-probe continuous temperature monitoring/alarm notification system widely used within refrigerators, freezers and walk-in coolers - where material storage temperatures must be maintained within a narrow range. By selecting a different probe type/temperature range the system can also be used for high temperature monitoring applications (e.g., within ovens, heating chambers and manufacturing processes).
For any application, the T Sentry Model 140 includes settable high/low temperature thresholds, audible/visual alarms (via beeper and LEDs), programmable alarm mute and "chirp" periods and a UL-listed plug-in power supply. Additional features
include alarm muting (for user-selectable
periods up to 32 minutes), optional relay contacts (for indicating temperature
and/or power failure conditions) and an optional alarm auto dialing system. The system is intuitive and easily programmed for any application (see video below).

NOTE:The T Sentry 140 can be used in a "stand-alone" mode AND/OR be integrated into our AMS, PC-based Ethernet network data logger/alarm notification system (using wired and/or wireless connections). This allows you to choose (at any time) between basic monitoring and alarm notification versus full remote network data logging and analysis (to meet Federal and State safety compliance guidelines and carry out statistical process control).
Also, since data portability and security are important for most users, we do NOT lock you into a cloud storage solution as an up-sell. There are many SaaS solutions available and we prefer to allow you to make this important decision based on your needs.
