Setting Up Your Dial Hygrometer

December 16, 2024

Our range of Hygrometers are designed to provide accurate humidity readings, perfect for those who love gardening or looking to keep a healthy home. This guide focuses on dial hygrometers, including the ClimeMET CM4303 and CM4303-SM, but it also provides general advice that may apply to other models like Fischer and Maximum dial hygrometers and the Whirling Hygrometer. They measure relative air moisture by measuring the amount of water vapour present in the air, as a percentage.

Note that the measurement range and accuracy vary by model. For example, the ClimeMET CM4303 has a measurement range of 10-100% RH with an accuracy of +/- 5% RH, while the Whirling Hygrometer boasts a higher accuracy of +/- 1% RH.

Pair with our range of Barometers and Thermometers to create your very own classic weather station.

To set your Hygrometer:

1. Choose the Right Location

-Position your Hygrometer in an area where it can remain undisturbed.

-Avoid direct sunlight and sources of heat and humidity that are not representative of the area you are looking to measure, such as a kettle.

2. Mount the Hygrometer

-For ClimeMET CM4303 and CM4303-SM models, use the keyhole fitting on the back to hang it in your desired location.

-If you’re using a Fischer, Maximum, or other brand of dial hygrometer, check the specific mounting instructions, as some may have a hook at the top or alternative mounting methods.

-Note that Whirling Hygrometers are handheld instruments and cannot be wall-mounted.

3. Allow for Adjustment

-Leave your Hygrometer for 24 hours to adjust to the humidity of its surroundings.
