Product Description

SpotSee WarmMark® is a single-use, ascending time-temperature indicator supplied in packs of 100 labels, expertly designed to monitor and record thermal exposure throughout cold chain logistics. Once activated, the indicator irreversibly changes colour upon reaching the preset temperature threshold and further reveals exposure duration with a visual countdown. This intuitive, irreversible design ensures swift decision-making at every point in your shipping journey.

Unlike basic temperature tags, WarmMark employs three sequential indicator dots—denoting brief, moderate, and prolonged exposure durations. For example, “brief” mode is reached at 2 hours above 0 °C / 32 °F, but just 30 minutes when over 25 °C / 77 °F. This nuanced feedback enables fine-tuned risk assessment for product viability.
SpotSee is a trusted partner brand, distributed in the UK and EU by Good Life Innovations Ltd.

  2. Activate: When ready to ship, pull the tab to initiate the indicator.
  3. Track Exposure: As the package warms, the indicator changes from white to red. For multi-dot models, the progression shows how long the threshold was exceeded.
  4. Decision-making: Upon delivery, assess shipment integrity via the visual progression. Act swiftly if prolonged exposure is detected.
