Overview
UK Thermax Irreversible Thermometric Paper (Model: 4 Grid J) is a series of temperature test labels that record the highest temperature reached by the label. These self-adhesive Thermometric Papers are composed of temperature-sensitive elements, sealed between heat-resistant substrates with transparent windows. Each element irreversibly changes Color when it exceeds the rated temperature. They provide a temperature history of the monitored surface and can be attached to the inspection report as a record.
Features
1. Long-term record of reaching the highest temperature
2. Self-adhesive labels
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 from 100 ° C to 154 ° C; +/- 4 ° C above 154 ° C
Principle
Temperature sensitive components utilize the precise melting points of a range of specially purified organic chemicals to produce a unique Color Change effect. Each temperature point uses a different compound, the coating is applied to the absorbent paper substrate, and when the rated temperature is exceeded, the chemical melts and is absorbed by the substrate, resulting in an irreversible Color Change.
Applications
Temperature monitoring, industrial inspections, and equipment maintenance
Steps
1. Paste the self-adhesive label on the monitored surface
2. Observe the Color Change of Temperature Sensitive Components
3. Record the highest temperature reached
4. Remove the label and attach it to the inspection report as a record
Notice
- Products below 50 ° C should be stored in a sealing bag in the refrigerator
- Products above 50 ° C should be stored at room temperature and 50% relative humidity (i.e. 20 ° C/68 ° F)
- Color change is irreversible, only maximum temperature is recorded
- Be careful not to delaminate when removing for reference
