Reefer Temp Monitoring
Remote Temperature Monitoring for Reefers
Continuous, real-time temperature and GPS tracking for refrigerated trailers — ensuring product safety, compliance, and operational efficiency across your entire cold chain.
How Reefer Temperature Monitoring Works
Tracker Systems combines GPS tracking with wired and Bluetooth temperature sensors to deliver continuous, verifiable cold-chain data. Wired sensors provide the highest accuracy and reliability with no battery concerns, while Bluetooth sensors offer flexibility and simplified installation for diverse fleet configurations.
-
Temperature Reporting
Using trackers such as the GV600 with wired probes or wireless Bluetooth sensors, readings are logged every 15 minutes when stationary and every 2 minutes in motion.
-
Location Correlation
Each temperature record is linked with precise GPS coordinates, giving you end-to-end visibility and proof of in-range operation for every load.
-
Wired & Bluetooth Options
Wired sensors offer long-term durability and zero maintenance, while Bluetooth sensors simplify setup in mobile or short-haul fleets.
-
Historical Data & Reporting
All temperature and GPS data is securely retained — never deleted — so you can produce audit-ready reports or automated summaries anytime.

Frequently Asked Questions
How often does the system record temperature and GPS data?
Temperature and GPS readings are typically recorded every 15 minutes when stationary and every 2 minutes in motion. These intervals can be customized per fleet.
Which is better: wired or Bluetooth temperature sensors?
Wired sensors are more reliable and maintenance-free, while Bluetooth sensors offer faster installation and flexibility. Many fleets use a mix of both for redundancy and convenience.
Can I get alerts when temperatures exceed limits?
Yes — you can define custom high and low thresholds for each probe and receive instant SMS or email alerts when conditions go out of range.
How long is my temperature data stored?
Tracker Systems retains all historical temperature and GPS data indefinitely, so you can retrieve complete records for audits or compliance reporting at any time.
