Big numbers are easy to read. Plastic film clings electrostatically and is easy to position on windows without tools. Great for use in campers as well as at home.
Mercury Free. 7" diameter.
For accurate readings and proper operation of this product, avoid mounting in direct sunlight or near a heat source. Never leave mounted on object, motor home, or boat while moving. Remove before getting underway. Not recommended for windows with film overlay or applied tints. Best if mounted when temperature is above 70 degrees Fahrenheit for proper adhesion.

Have one of these, but needed to replace it. So glad I found this one.
