Product Overview:
NOTE 1: For 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 sample storage temperatures must be maintained within a tight range. It can also be used in high temperature applications (e.g., within ovens, heating chambers and other related manufacturing processes) because it can be configured to operate in temperature ranges between -200 to +400 degrees C.
No matter what application it is used for, 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).
NOTE: Both the T Sentry 140 and MPS Series Systems can be used as “stand-alone” systems and 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.
