What is the difference between a humidistat and a hygrometer?

Where would you typically find a humidistat?

In buildings with sensitive environmental needs: museums, wine cellars, cigar humidors, greenhouses, and modern homes with whole-house humidity control systems.

Is a humidistat the same as a thermostat?

No, they are analogous but for different conditions. A thermostat regulates temperature, a humidistat regulates humidity.

Can I use a humidistat on its own?

No, it is a control device. It must be connected to a humidifying or dehumidifying appliance to function.
