Best Hygrometers To Monitor Humidity Around Your Home

Have you ever trekked through a dry desert or backpacked through a rainforest? The main difference between the two is the amount of humidity present where a desert has little or no water content in the air while the rainforest is steamy due to water vapor. Hygrometers are specially designed to measure the amount of humidity in the atmosphere. As a weather person, gardener or just an outdoor lover, it’s always important to know the amount of water vapor out there to help with planning.

Humidity is measured in two ways; the relative humidity and the specific humidity. Relative humidity is measuring the amount of water vapor in the air compared to the maximum humidity that could be at that particular temperature. Specific humidity is the mass of water vapor per kilogram mass of air. Now that we know what to look for when measuring humidity, let’s look at these special weather instruments known as hygrometers.

These devices have come a long way since the early years when a strand of hair was used to determine the amount of water vapor outside. Now, there are various types of hygrometers that are being used at home, offices, farms and commercial setups. In here, we have compiled a list of the best hygrometers available in the market today that will give you precise and accurate measurements for all your needs.

Hygrometers Buying Guide

Wouldn’t it be nice to have a little weather station inside your home? That way you can effectively monitor different weather elements that if not checked can wreak havoc to your family. One instrument that you need not miss in your home is a hygrometer that helps measure the amount of humidity in the atmosphere. Knowing the moisture content in your home can help you take the necessary measures in case of high humidity that cause the growth of molds and even expose the kids to flu.

Relative Humidity Versus Specific Humidity

When dealing with a hygrometer, there are two measurements that you will need to keep in mind: relative humidity and specific humidity. Relative Humidity (RH) is the easiest to measure and it gives the amount of water vapor in the air. It’s usually expressed as a percentage that gets higher as humidity increases. You will often find this figure displayed on most hygrometers alongside the temperature reading.

Types of Hygrometers

  • Hair tension hygrometers – The principle of displacement is applied here where hair or nylon is used to determine expansion and contraction due to humidity. They are inexpensive and can’t be tampered with.
  • Psychrometers – These are among the most common and match a pair of wet and dry bulbs. There’s usually a chart that compares the difference in temperature between the two gadgets.
  • Mechanical hygrometers – Are often simple but expensive devices that have been used to measure humidity for decades. They can be mounted on walls or placed outdoors as meters. They require constant calibration to improve accuracy.

Factors to Consider When Buying a Hygrometer

There’s a couple of things that you need to keep in mind before buying your hygrometer, So, they include:

  • Humidity range – Most hygrometers will give you a range of the percentage of RH that they can adequately measure. The range may fall between 0% for low humidity and 100% for high humidity.
  • Display – It’s important for the gadget to have a good display that can be easily read at any time.
  • Calibration – Since the humidity changes often, it’s important for the gadget to reset to capture the current readings or allow for manual calibration.
  • Other features – There are numerous other features designed to enhance a hygrometer such as remote sensors, recording of max/min readings, an LCD backlight for night reading and having multiple mounting options.

Conclusion

Your home requires a good hygrometer that will accurately measure the amount of humidity in the air. Whether it’s the basement, baby’s bedroom or even the kitchen, hygrometers are important for monitoring water vapor around your home or enterprise. Hopefully, this review has shed light on the best hygrometers out there and you will no longer use your imagination to estimate the amount of water vapor around you.
