20″ Large Classroom Thermometer
by Learning Resources

This oversized thermometer is perfect for the classroom. It features a large, easy to read temperature readout with Farenheit on one side and Celsius on the other. With temperatures ranging from -40° to 50°C and -40° to 120°F, and mouting points on the back, the thermometer can be placed inside or outside the classroom.

The liquid inside the thermometer is alcohol-based instead of mercury-based, making it much safer for handling. The plastic housing is approximately 20″ long, and 4.5″ wide.
