Each Style/Category Below Contains Various Temperature Ranges for each Non-Reversible Temperature Label.
These labels are perfect for monitoring temperature of items that are subjected to temperatures unfit for humans. Additionally, Non-Reversible / Irreversible Labels are also used in the cold chain monitoring method which monitors food during shipping. Each temperature point contains a special formulated wax-ink that melts and is absorbed into a black substrate. The color change becomes permanent which allows the end user to keep record of the unfavorable temperatures the product is subjected to.
Most Non Reversible labels go through a permanent change in usually less than 1 minute for response time.
These labels cover a range from 84°F ~ 554°F ( 29°C ~ 290°C) . View our Time/Temperature Labels that show how long the temperature was above its threshold.
