Cold Chain Monitoring for Logistics
From the loading dock to the last mile, KelvinTrack tracks the temperature of your chilled and frozen goods, alerts you to any excursion, and keeps a complete audit trail, in warehouses as well as in transport.
The essentials
Cold chain monitoring in logistics should not rely on paper logs filled in once or twice a day. KelvinTrack continuously measures, 24/7, the temperature of your cold rooms and refrigerated vehicles, with sensors accurate to up to ±0.05 °C. You receive an SMS and/or email alert as soon as a threshold is crossed, and the timestamped, tamper-proof history exports as a HACCP-compliant PDF report in one click. Trial available on request for large deployments. French solution, based in Montpellier.
Keeping control of the cold chain end to end
By the KelvinTrack team · Updated
Cold chain monitoring in logistics means measuring the temperature of chilled and frozen goods, in warehouses as well as in transport, to prove they were kept within range. The EN 12830 standard defines the requirements for temperature recorders used in the transport and storage of goods, and the ATP Agreement (transport of perishable foodstuffs) governs the international transport of perishable goods. KelvinTrack continuously monitors your cold rooms and vehicles; depending on the equipment, position is tracked alongside temperature. An alert is triggered as soon as a reading falls outside the defined range, and the timestamped history documents cold chain compliance for your customers.
In cold chain logistics, a temperature excursion can happen anywhere: a cold room drifting overnight, a refrigeration unit failing on the road, a dock where pallets wait too long. Without continuous measurement, these incidents are only discovered on receipt - too late to react.
KelvinTrack continuously monitors your storage units and vehicles. Every reading is timestamped; depending on the equipment, position is also tracked. You are alerted as soon as a temperature falls outside the defined range, and you have a complete history to prove cold chain compliance.
From storage to transport, with no blind spots
In cold chain logistics, a blind spot is every moment when no one is reading a thermometer: overnight in the warehouse, over the weekend, on the road between two platforms. KelvinTrack removes them by monitoring your cold rooms, warehouses and refrigerated vehicles from a single centralized interface, with minimum and maximum temperatures recorded continuously. Depending on the equipment, position is tracked alongside temperature, which makes it possible to pinpoint exactly where an incident occurred during a run. As soon as a reading falls outside the defined range, you are notified immediately, wherever the excursion happens along the chain. And because customer disputes are settled with evidence, the timestamped history can be exported to prove preservation over the entire period concerned. The concrete result for the operator: fewer manual reading rounds, more visibility, and continuous traceability from the loading dock to the last mile.

For distribution operators
Cold chain logistics operators include cold storage warehouses, temperature-controlled carriers, food distribution platforms and distributors of temperature-sensitive health products. They all share the same obligation: proving that goods stayed within their temperature range, from storage to delivery. KelvinTrack adapts to each of these contexts: multi-unit monitoring for large-capacity cold rooms, temperature tracking and, depending on the equipment, position tracking for vehicles on the road, and continuous traceability between the platform, transport and delivery points. Each type of goods keeps its own thresholds, allowing chilled, frozen and sensitive products to be monitored side by side. The timestamped, exportable history serves as evidence for your customers and in the event of a dispute.

How it works
Deploying cold chain monitoring comes down to four steps: equip, configure, monitor, prove. Sensors are installed in your cold rooms and refrigerated vehicles, then you define the acceptable temperature ranges for each type of goods. Readings stream continuously to your dashboard; depending on the equipment, position is tracked alongside temperature. Transmission goes through an Android 12 or newer phone running the free app: it reads KelvinTag sensors over Bluetooth and uploads the readings over WiFi or mobile data. In the event of an excursion, an alert is sent immediately and the timestamped history documents cold chain compliance. For a large deployment, a trial can be arranged on request.

Paper logs versus automated monitoring: what changes day to day for a logistics manager.
| Manual paper log | With KelvinTrack | |
|---|---|---|
| Reading frequency | Typically 1 or 2 manual readings per day, during staffed hours | Automatic continuous readings, 24/7, including nights and weekends |
| Alerts | No alerts: an excursion is discovered at the next reading, never at night | SMS and/or email alert as soon as a threshold is crossed, multiple recipients possible |
| Data reliability | Handwritten transcription, exposed to omissions and reading errors | Timestamped, tamper-proof data, recorded with no manual entry |
| Audit preparation | Paper binders to gather and check by hand | HACCP-compliant PDF reports, one-click export |
| Measurement accuracy | Depends on the thermometer used and on the operator's reading | Sensors with an accuracy of up to ±0.05 °C, calibrated accuracy shown per sensor |
| Day-to-day cost | Staff time spent on every reading and its archiving | Automatic readings with no daily intervention; trial available on request |

Order the KelvinTag sensorFrequently asked questions
The questions logistics managers ask most often are practical ones: how to prove cold chain compliance to a customer, what happens if a vehicle loses network coverage on the road, and how long it takes to prepare for an audit. The answers come down to a few principles. Every reading is timestamped and tamper-proof; it exports as a HACCP-compliant PDF report in one click, which prepares you for a customer audit as well as a DGCCRF inspection. On the road, each sensor keeps recording to its own memory (3 years of readings); out of range of the relay phone, readings catch up automatically once back in range, and if the phone loses the network it keeps them and uploads once the connection returns: no data is lost, but no alert leaves during these gaps. And to check that the solution fits your operation, a trial can be arranged on request for large deployments.
Can temperature be tracked during transport?
Yes. The sensors track the temperature of refrigerated vehicles on the road, and position can be tracked alongside it depending on the equipment.
How can I prove cold chain compliance to a customer?
The temperature history is timestamped and exportable: you can provide proof of preservation for the entire period concerned.
Can I monitor a warehouse and a fleet in the same place?
Yes. Storage units and vehicles are brought together in a single interface, with a centralized view.
What happens if the refrigeration unit fails?
As soon as the temperature falls outside the defined range, an alert is sent immediately so you can respond quickly.
Can the solution handle several types of goods?
Yes. Each unit has its own thresholds, allowing you to monitor chilled, frozen and sensitive products side by side.
What happens if a vehicle loses connectivity?
The sensors keep recording to their own memory and the relay phone keeps the readings it has received: everything uploads as soon as the network is back, with nothing lost during a run. However, no alert leaves while the relay has no connection: alerts arrive once the network returns. The relay uses WiFi or mobile data.
Can I try it before committing?
For a large deployment, yes: we look at a trial case by case. Write to us describing your site and how many units you need to monitor. There is no self-service trial.
Do I need to buy a dedicated gateway to transmit the readings?
No. There is no gateway to buy and no subscription. The relay is an Android 12 or newer phone running the free KelvinTrack app, left on site within Bluetooth range of the sensors (up to 50 m depending on the environment); we recommend keeping it plugged in. It sends the readings over WiFi or mobile data to the dashboard, which alerts the people concerned by email, SMS and push notification, iPhones included. If it loses internet, readings are kept and upload once the connection returns, but no alert leaves the site in the meantime.
Is the sensor accuracy sufficient for sensitive products?
Yes. KelvinTag sensors are inspection-grade and offer accuracy of up to ±0.05 °C. When a sensor is calibrated, its calibrated accuracy is displayed individually in the interface; otherwise, an estimated accuracy from the sensor specification is shown. This fine level of measurement faithfully documents actual storage conditions for low-tolerance goods, such as temperature-sensitive health products.
Do the sensors withstand negative cold rooms and humidity?
Yes. KelvinTag sensors are IP68 waterproof and operate from -40 °C to +85 °C, which covers negative cold rooms, frozen goods transport and humid warehouse environments. Their battery lasts 3 years, the hardware carries a 3-year warranty and is purchased once, with no per-sensor subscription and no particular day-to-day maintenance.
Who gets notified if a temperature drifts at night or over the weekend?
Monitoring runs 24/7, without depending on anyone being on site. As soon as a threshold is crossed, an alert is sent by SMS and/or email, as you prefer, and you can add several recipients: the operations manager, the on-call contact, the maintenance provider. A cold room drifting on a Saturday evening no longer goes unnoticed until Monday morning.
What do I present during an official inspection?
The temperature history, timestamped and tamper-proof, exports as a HACCP-compliant PDF report in one click: you present complete records for the requested period, with no binders to piece together. European regulation 852/2004 requires temperature monitoring without imposing a method: automatic, timestamped recording meets that requirement, and the system is ready for a DGCCRF inspection.
In summary
KelvinTrack monitors the temperature of warehouses, cold rooms and refrigerated vehicles 24/7, with position tracking depending on the equipment.
Immediate SMS and/or email alerts as soon as a temperature falls outside the defined range, with multiple recipients possible.
