Temperature and Humidity Meter

The comfort level of your home depends a lot on whether it’s warm and dry or cold and damp. By checking each room’s temperature and humidity (the amount of water vapour in the air), you’ll know if you need to adjust your heating or ventilation — or both.

Use the temperature and humidity meter in different parts of each room, at different times, to check if they’re too hot or cold, or too dry or damp. Fresh air is essential for a healthy home, so the key is to ensure you have enough ventilation to let damp, stale air out, while still keeping as much heat in as possible.

To check the levels in your home, simply turn the temperature and humidity meter on and place it on any stable surface, as long as it’s not heated. Tables, windowsills and bookshelves would all be good places to test. For rooms you spend time in, like your kitchen or living room, the ideal temperature range is between 18 degrees and 20 degrees. The ideal levels for humidity are between 40% and 60%.

If you find humidity is an issue, there may be ways you can manage it, such as improving ventilation.
