Sentinel Web-based Temperature Monitoring System for Freezers and Refrigerators

The new Sentinel system remotely monitors temperatures in freezers and refrigerators to protect valuable food assets, medical specimens and the cold storage equipment itself.
The system is ideal for food manufacturing, processing and storage facilities, hospitals, laboratories, pharmacies and food service and retail locations.

The Sentinel system monitors up to 12 different environmental and equipment status conditions including temperature from -109 °F to 168 °F, humidity, power failure, water detection and equipment status.

Instant alerts to your phone or email

When the system identifies issues, it instantly sends alerts via phone, text or email over a standard Internet connection. It can also deliver daily event reports and supervises its own internet connection.
Users can access information and make system changes from any web-enabled device or mobile app.

User friendly, cloud-based system

The system stores all readings in the cloud, which protects against data loss, provides unlimited information storage and allows multiple devices to be managed from one account.
No software is required, so installation, integration and management are easy.


The standard Sentinel system is Ethernet based, but the product is also available with a cellular option for locations where Internet connectivity is not available.

Refrigerator Temperature Monitoring

Monitoring the temperature of your refrigerator doesn’t have to be a complicated process.

Whether you have a household, consumer grade unit or a pharmaceutical-grade under the counter or full sized refrigerator, EDAC has a temperature monitoring solution to keep you alerted of any temperature changes and power failures.

Our recommended temperature monitoring solutions also track temperature history and provide detailed datalogs.

Ultra low temperature sensors

For monitoring temperatures inside of a refrigerator, EDAC recommends using the 2.8K Type Temperature Sensor in Glass Bead Vial.

The glass bead filled vial will buffer any momentary fluctuations that may cause a preliminary alarm dial out, such as defrost cycles, opening of doors, and fans circulating air. The glass beads will slow the response time of the sensor allowing normal daily operations to occur without having an alarm.

Equipment and Power Failure Monitoring

In addition to monitoring the actual temperature inside of the refrigerator, devices can alert personnel to take action before temperatures actually start to go out of range.

They can be wired to the alarm panel of many pharmaceutical-grade units. The refrigerator will trip an alarm if it diagnoses a problem internally and the device will pass along the alarm message via phone, email or text message. It will also monitor for power failure wherever the device is plugged in.
