3温测温纸 150°F 160°F 170°F

 Our completely waterproof 3-Temp Thermolabel features temperature sensitive elements that produces a non-reversible white to black color change at the rated temperature. This provides a clear indication that the temperature has been reached. The temperature elements are fully enclosed and protected with a clear plastic overlay, providing both moisture protection and durability, making these labels ideal for a wide range of applications. The self-adhering indicators are available in packages of 16 labels each. Store in a cool, dry place.
