One-way indicator labels printed with irreversible thermochromic ink. The window changes colour when the set temperature is exceeded and does not change back, so the receiver can see that the limit was passed. Used as a visual check on cold-chain parcels, food deliveries, electrical joints and equipment. The activation point is set to your limit and confirmed by sample testing.
