Global – October 20, 2026 -- SpotSee is urging cold chain teams to select temperature monitoring by the decision it must support, and has matched five technology categories to specific shipment questions.
Irreversible indicators answer whether a limit was crossed
Irreversible threshold indicators, such as SpotSee's Thermax, give receiving teams visible evidence that specified temperature conditions were reached. The indication does not reset once activated. They suit cases where a clear visual result matters more than a complete temperature history.
WarmMark QR tracks cumulative exposure and digital records
WarmMark QR combines cumulative time-temperature indication with QR-enabled digital documentation. It targets shipments where both temperature and duration of exposure matter. The QR function lets teams document shipment condition at key points in the journey, supporting traceability and follow-up.
FreezeSafe QR and ColdSNAP target cold damage
FreezeSafe QR pairs freeze indication with QR-enabled digital documentation, while ColdSNAP addresses applications where cold or freezing exposure is the primary concern. Products can stay within their upper temperature range and still be compromised by freezing, which makes freeze monitoring a separate decision.
Data loggers record full journeys, but not every shipment needs one
Electronic data loggers create a time-stamped record showing when an excursion occurred, how long it lasted, how temperature changed in transit and whether multiple excursions took place. SpotSee says shipment risk, product value, quality requirements or investigation needs should justify that level of detail. If the only question is whether a defined condition occurred, an indicator may suffice with less complexity.
SpotSee Go adds in-transit visibility for critical loads
SpotSee Go provides connected monitoring for shipments where waiting until receiving would be too late to act. SpotSee lists five use cases:
- Particularly valuable or sensitive shipments
- Excursions that may require intervention before delivery
- Delays or route changes that could affect product condition
- Complex supply chains needing greater visibility
- Cases where post-delivery findings come too late
Final selection should also weigh product sensitivity, acceptable temperature range, shipment duration, shipment value, regulatory or quality requirements and the action teams will take on an excursion.
SpotSee plans to release a ColdChain Product infographic comparing the technologies by application.
