Thermopaper® single temperature test strips come in packages of 50 each.

Thermopaper® non-adhesive indicators provide a faster response time and are for use when a clean and dry test surface is available. Strips consist of a temperature sensitive element 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. Strips are not waterproof and therefore cannot be used with liquids or excessively high ambient humidity. Store in a cool, dry place.
