OMEGA Engineering, Inc. Non-Reversible Temperature Labels TL-4

The TL-4 Non-Reversible Temperature Labels from OMEGA Engineering, Inc. are designed for temperature monitoring in various applications, including general, aeronautical, electrical, and HVAC. Each label measures 30 x 18 mm (1.2 x 0.7 inches) and features an adhesive back for easy mounting on surfaces with temperatures above -40°C/°F. The labels indicate temperature changes by turning black when exposed to specific temperature thresholds. The TL-4 series offers a range of temperature options, including TL-4-105 (40°C/105°F), TL-4-130 (54°C/130°F), TL-4-170 (77°C/170°F), TL-4-210 (99°C/210°F), TL-4-250 (121°C/250°F), TL-4-290 (143°C/290°F), TL-4-330 (166°C/330°F), TL-4-370 (188°C/370°F), TL-4-410 (210°C/410°F), and TL-4-465 (241°C/465°F). The accuracy of the labels varies with temperature, providing ±1°C (1.8°F) accuracy up to 99°C (210°F), ±1.5°C (2.7°F) from 100°C (212°F) to 154°C (309°F), and ±1% and ±1°C (1.8°F) from 160°C (320°F) to 280°C (536°F). These features make the TL-4 labels suitable for precise temperature monitoring in critical environments.
