La Crosse Technology Analog Dial Hygrometer and Thermometer

An easy-to-read analog dial that measures indoor temperature and humidity without batteries.

• Measures temperature and humidity on a single dial
• Color zones indicate comfort levels
• No batteries required for operation
• Can be wall-mounted or freestanding
• Supports NGSS Earth systems standards (MS-ESS2-6)

This analog dial instrument measures both temperature and humidity using mechanical components. Students can observe how air moisture and temperature affect comfort levels indoors.

Because it does not require electricity, the device provides a clear demonstration of mechanical measurement systems. It supports lessons on atmospheric conditions, environmental balance, and how climate influences living spaces.
