Product Overview:

NOTE 1: For multi-type/multi-sensor applications, visit our MPS Series monitoring alarm system page.

The T Sentry Model 140 is a stand-alone single probe temperature monitoring/alarm notification system widely used within refrigerators, freezers and walk-in coolers where storage temperatures must be maintained within a tight range. By selecting probe type/range the system can also be used in high temperature applications (e.g., within ovens, heating chambers and manufacturing processes). Sensor selection enables the unit to operate between -200 to +400 degrees C.

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 easily programmed for any application (view the video below to see for yourself).

In addition, both the T Sentry 140 and MPS Series can be used as "stand-alone" systems which can LATER be integrated into our AMS, PC-based Ethernet network data logger/alarm notification system (using wired and/or wireless connections). This allows you to grow into complete statistical process control while maintaining real-time monitoring and alarm indication.
