## Fleet temperature monitoring devices from Radius

### Stratus 79: Advanced refrigeration GPS tracker

The Stratus 79 is a GPS tracker designed for refrigerated fleets. It monitors reefer temperatures in real time, helping fleets protect temperature-sensitive goods and prevent spoilage.

The device connects to the reefer unit using a cable from the installation kit. It works with [Carrier](https://www.carrier.com/truck-trailer/en/north-america/products/na-truck-trailer/lynx-fleet/) or [ThermoKing](https://www.thermoking.com/na/en/connectedsuite-telematics/tracking-telematics.html) refrigeration units, pulling temperature data directly from the source. This setup enables real-time temperature tracking from the reefer unit.  

### What reefer tracking monitoring tracks:

-   **Temperature monitoring:** Box temperature, ambient air, set temperature, door status, fresh air status and alarm status.
-   **Reefer performance:** Duration of electric power usage; battery voltage levels; electric or diesel operational mode; cumulative switch-on hours; total standby duration.
-   **Vehicle and driver behavior:** Speeding; trip history; trip start/stop; idling; sudden braking; harsh braking; aggressive acceleration; sharp cornering.
-   **Engine diagnostics:** Fault codes and operating modes.
-   **Location tracking:** GPS tracking, Wi-Fi geofencing, cell tower triangulation and geofences with points of interest.

## Compliance with regulatory standards for reefer fleet monitoring

Fleets transporting perishable products must follow U.S. laws like the [Food Safety Modernization Act (FSMA)](https://www.fda.gov/food/guidance-regulation-food-and-dietary-supplements/food-safety-modernization-act-fsma). A reefer temperature monitoring system helps companies stay compliant by tracking temperatures, sending alerts and keeping records.

-   **Follows FSMA rules:** Temperature monitoring ensures shipments remain within the correct range.
-   **Live tracking:** Remote monitoring alerts fleets if conditions change.
-   **Automated recordkeeping:** A temperature monitoring solution stores data for audits and compliance.

With an advanced monitoring system, fleets can follow regulations, protect shipments and reduce risks.
