Numeric Thermo Patch, WR Series

[Features]
· Heated temperature is displayed with numbers.
· When the product changes its color at a specific temperature, the color returns when cooled. It is a reversible temperature indicating material that can be used repeatedly.
· When the temperature increases, a number appears, and when the temperature decreases, it disappears. Because the peripheral part and number part is the color before changing, the change by temperature raise is easy to see.
