All-In-One Solution
Streamlined refrigeration monitoring from loading to transportation, and all the way to the terminal—ensuring minimal temperature-related spoilage costs.
Monitor temperature, location, and supported door activity across refrigerated shipping containers. Use the appropriate powered, battery-backed, or standalone architecture for terminals, storage, and transit.
Environmental visibility for containers and remote cargo
Our refrigerated container monitoring system utilizes our industry-leading wired and wireless temperature sensors to actively track and monitor the temperature and location of reefer shipping containers and valuable cargo. This system provides customers with 24/7 temperature visibility, the ability to monitor unlimited cold zones simultaneously, real-time and historical reports, and real-time alerts on temperature deviations, all while minimizing temperature-related spoilage costs.
Streamlined refrigeration monitoring from loading to transportation, and all the way to the terminal—ensuring minimal temperature-related spoilage costs.
Monitor reefers from any location with our powerful cloud platform. Set up alerts for connection loss or temperature deviations and access real-time and historical data to ensure optimal performance.
Seamlessly and automatically record temperature across your cold chain, removing the need for manual record keeping by creating a unified, automated temperature logbook.

Review current and historical temperature readings alongside container location to understand where an exception occurred and which shipment requires attention.

Place supported wired or wireless temperature sensors in the areas that need independent monitoring, then review each zone with its own configured limits.

Supported devices retain temperature and location records locally during cellular coverage gaps and upload them to Fleet.Net after service returns.

Notify designated team members when readings move outside configured high or low limits, or when a supported door event requires attention.

Review time-stamped temperature history, container location, supported door events, and exceptions for quality, customer, and compliance workflows.

With active refrigeration monitoring and real-time alerts, you can immediately take action when temperatures deviate from your set thresholds. Whether your product is on board a vessel, en route, or at a fixed location, you are always in control.

The temperature sensors are small and can easily fit inside the Supply air vent (as seen in the picture). The temperature sensor is actually inside the vent while the solar unit sits just outside the vent so that it can better interface with the devices that pickup the data from the sensor.

“When reefers are left over the weekend at the freight or main office, the reefer technician can monitor both locations using the mobile app. If you have reefers running at either location, your technicians can set up alerts to notify them if:
Technicians can also access the current temperatures of any actively monitored reefer.

At sea, walking up and down to take temperature readings is not always safe, which is why it’s done only every few hours. With this system, a technician will know in advance if a reefer is in trouble before making their rounds.
Configure refrigerated-container monitoring for ocean, rail, terminal, yard, and intermodal cold-chain operations.
Reefer trailer temperature monitoring helps carriers cut the risk of cargo loss and asset damage and minimize temperature-related spoilage costs. It ensures cargo temperatures stays within the acceptable range with the use of sensors to alert if any sudden temperature changes occur.
A GPS temperature monitoring device is one that combines GPS tracking, telematics and reefer temperature control in one solution.
Our Piccolo STX is capable of monitoring up to 6 different cold zones simultaneously with wired digital temperature sensors. We also offer wireless temperature sensors to monitor multiple compartments at once.
The benefits of refrigerated trailer tracking include gaining visibility & control into the location and temperature status of your perishable assets as they move through the cold chain, while reducing operational costs & cutting the risk of cargo loss and asset damage.
A GPS temperature sensor and a GPS temperature monitoring device are basically interchangeable definitions. Both systems help monitor real-time temperature while providing GPS fleet data.
