Looking to buy the best hygrometer for your home but you are unsure what to look for? A useful device for homes with high humidity, hygrometers are a worthwhile investment for those looking to monitor water vapour in the air inside their home, although choosing the right product can be difficult.

Check out the handy buying guide below for all the information that you need to choose the best hygrometers for your home!

What are hygrometers?

A hygrometer is a device that measures the humidity in the air inside your home, just like a thermometer measures the temperature. It gives relative humidity reading in a percentage, so you can determine whether there is too much moisture in the air, which can cause issues like mould and make for a generally uncomfortable environment.

Why should you buy a good hygrometer?

A good hygrometer has many uses around the home. The most notable reason to buy one is that it can help prevent mould by indicating when there is too much moisture in the air Moreover, too much humidity in the air can make the environment unpleasant, so by using a hygrometer to monitor humidity, you can adjust air-con or heating to make it more comfortable.

Another popular use of a hygrometer is to monitor humidity in a growing environment like a greenhouse. Some plants require a certain humidity to properly grow, so anyone that loves indoor growing should benefit from using a hygrometer.

Struggling to find the best hygrometer? Here are some things to think about that will make it easier to find a great hygrometer:

  • Display Screen: A hygrometer with a large, clear display screen is recommended for easier reading of data. It may help to have a backlight to monitor readings in darker spaces too.
  • Logging: Does the hygrometer log data measurements throughout the day? It’s a great feature because it can let you measure the high and low points throughout the day when you may not be home, giving a clearer picture of when humidity is at its highest and lowest.
  • Multifunctional: Many hygrometers are multifunctional devices, so think about whether there are extra functions that may be useful. For instance, many have a thermometer function a clock and prove barometric readings.

What is the best kind of hygrometer in the UK?

There are several popular types of hygrometers that you can buy. Each one has its pros and cons, so be sure to think about which of these best meets your needs!

  • Electrical Hygrometer: Uses resistance or capacitance to measure the humidity in the air. With a resistance hygrometer, the device measures humidity through the changes in resistance when electricity flows through a ceramic object, while a capacitance measures the humidity using the electric charge between two metal plates.
  • Psychrometer: Consists of two thermometers that use a dry and wet bulb to measure changes in humidity. It works by measuring the difference in temperature between each thermometer, which drops in the wet bulb when there is humidity in the air.
  • Dew Point Hygrometer: For professional use and possibly the most accurate type of hygrometer, this works by measuring the saturation of moist air in gas, making it effective at measuring very small amounts of moisture.
