Overview
The UK Thermax Irreversible Thermometric Paper (Type 4 Grid B) is a temperature test label that records the maximum temperature reached by the label. The product consists of a series of temperature-sensitive elements, sealed between heat-resistant substrates with transparent windows, each element changes Color significantly and irreversibly when the rated temperature is exceeded, providing a temperature history of the monitored surface and can be used as an inspection report attachment.
Features
1. Long-term record of reaching the highest temperature
2. Self-adhesive label design
3. Silver to Black Color Variation
4. Immediate Response
5. Resistant to oil, water and steam
6. High Accuracy: +/- 1 ° C below 100 ° C; +/- 1.5 ° C at 100 ° C to 154 ° C; +/- 4 ° C above 154 ° C
Principle
Thermometric Paper uses a series of precise melting points of specially purified organic chemicals to produce Color Changes. A different compound is used at each temperature point, and the coating is applied to the special absorbent paper substrate. When the rated temperature is exceeded, the chemical melts and is absorbed by the substrate, resulting in irreversible Color Changes.
Applications
Temperature monitoring, industrial inspections, and recording reports
Steps
1. Paste the self-adhesive label on the monitored surface
2. Observe the Color Change of Temperature Sensitive Components
3. Remove the label and attach it to the inspection report as a record
Notice
• Products at 50 ° C or below need to be stored in a sealing bag in the refrigerator
• Products above 50 ° C should be stored at room temperature and humidity (i.e. 20 ° C/68 ° F, 50% relative humidity)
• Color change is irreversible, only the highest temperature is recorded
