Hygrometer Thermometer Temperature Fahrenheit Greenhouse Review

I used these to monitor the heat coming from a heater lamp. That was great. Helped keep my baby floss at a safe temperature.

I wish they were double sided. I would have preferred the temporary display to be larger. They are small but still seem to work.

All four sit in one place for more than two hours. All have different temperature and humidity levels. Just like other people said. My thermostat is in the house, according to our thermostat 74° and 44% humidity.
