Temperature Strips Our waterproof 5-Temp ThermolabelÂ® 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. While applicable to a wide range of industries, the 5 level ThermolabelÂ® is a popular choice for screen printers using low cure inks. Store in a cool, dry place. The self-adhering indicators are available in packages of 16 labels each.
