An Economical Way to Determine Temperature

Microencapsulated, non-toxic liquid crystals change color to indicate changes in temperature. Color changes revert back to normal so labels can be used again and again.
Specifications: Actual temperature is highlighted as green. Brown indicates the temperature above the actual reading and blue indicates the temperature below it. 16-Level and 48-Level Labels measure temperatures in 2°F increments. (°F/°C scale.) Measure 1/2" x 5". Refrigerator and Freezer Thermometers have a plastic housing. Self-adhesive strip keeps each device secure. Measures 5-3/8" x 3/4".
