Cold chain monitoring today is either manual or patchy
USB data loggers are reliable temperature recorders. The cost isn't the device, it's the workflow: prepare, activate, place; at delivery, retrieve, download, log into QA. Across thousands of shipments, that's hours per delivery. Missed loggers mean lost records.
Cellular trackers automate the upload at higher cost per unit and with their own coverage gaps.
One Tag, every reading
Logger Tags handle both jobs: real-time upload in coverage, offline capture when out of range. One device covers what cellular and USB loggers do separately, at a workable per-unit cost.
Every phone, tablet and handheld running Blecon Agent becomes a Hotspot. Signals flow into Blecon Track in real time as goods move through your operation. The receiving team just unloads.
When Tags travel beyond coverage range they store sensor readings locally. When back within range, the full record uploads automatically.
Real-time alerts fire wherever there's a Hotspot. The full record arrives in Track either way.
What you'd deploy
Three components: Tags in shipments, Agent on your team's existing devices, rules in Track.
Waterproof BLE Tag with temperature sensors. Place in each shipment, scan to associate. Reusable Logger Tag or disposable Sensing Tag depending on operation.
Software on the phones, tablets and handhelds your team already carries. Each device becomes a Hotspot, capturing Tag signals as it moves.
Rules and alerts in Track
Configure rules for temperature breaches, customer-site dwell, route deviations and return-to-base. Alerts route in-app, by email or to your incident management system via webhooks.
Where this fits in cold chain
Cold chain has many shapes. Where Blecon's logger Tags fit:
Time-sensitive shipments where every degree of temperature variation affects shelf life and product loss.
Frozen and chilled distribution
Long-haul delivery to retail and food service.
Cold storage operations
Warehouses and distribution centres handling temperature-sensitive goods for multiple customers, with per-shipment audit trails.
What changes in your operation
The receiving team unloads as normal. Data has already arrived in Track during the journey, not at the end of the day.
Operations works from Blecon Track. Each shipment builds its temperature record live. In-coverage drift fires an alert whilst there's still time to act. Offline drift uploads on the next Hotspot pass, closing the audit trail.
The compliance file builds itself. Every shipment, every leg, in Track.
Supporting your compliance work
Cold chain operates within food safety and pharma regulations, HACCP plus regional frameworks. Blecon supports the workflows compliance teams need: complete sensor history per shipment, automatic audit trail generation, configurable retention and exportable temperature records as PDF or CSV.
