Definition & Explanation
Transporting temperature-sensitive goods by sea requires more than a correctly set refrigeration unit: real-time reefer cargo condition monitoring continuously tracks parameters such as temperature, humidity, light exposure, door openings, and vibration throughout the entire voyage. Sensors inside the reefer container transmit data via telematics to the shipper, freight forwarder, and consignee; any deviation from the set range triggers an immediate alert. This protects perishables—fish products, berries, vaccines, pharmaceuticals—from quality loss and provides unbroken documentation in the event of a claim. For many food imports and pharmaceutical shipments, regulators now require such records as proof of cold chain integrity. Unlike post-voyage temperature logging, real-time monitoring enables active intervention—such as cargo transfer or refrigeration adjustment—while the shipment is still in transit.
