5温测温标签纸 经典型 190-230°F
英文名：5-Temp THERMOLABEL Classic 190-230°F
Our 5-Temp Thermolabel features five incremental temperature sensitive elements that produce a non-reversible white to black color change at their rated temperatures. This provides a clear indication of which temperature has been reached. The self-adhering indicators are available in packages of 16 labels each. Labels are not waterproof and therefore cannot be used with liquids or excessively high ambient humidity. Store in a cool, dry place.
