Review on Liquid Thermometer Plastic Organic B60770 1200 by Chris Scalia

The thermometer arrived with an air bubble in the liquid which offended the scale 20 degrees. A simple solution is to tie a rope over the top and swing it vigorously to use centrifugal force to dislodge the air bubbles. Works great after setup. Very accurate when checked with an IR thermometer. There are no batteries, there is nothing to break, a convenient plastic mount. Hang it on a teacup hook and it becomes the perfect room thermometer. The scale goes up to 220 degrees Fahrenheit, so it can hang on the mirror in the car and indicate intense heat build-up in the summer sun. Buy a few more, one for each floor of the building and one for each car.
