How Do I Choose the Best Humidity Monitor?

Humidity is a critical aspect of various meteorological and industrial processes, as well as residential and commercial premises where there’s need for comfortable moisture levels. In industrial areas, humidity is important in greenhouses and coating, painting and chemical processes.

Whereas in residential areas humidity is critical in apartments and homes, it also finds use in offices in commercial areas. At home, you can use dehumidifiers or even humidifiers to fine tune your humidity levels. Controlling the level of humidity in humid rooms is also crucial in controlling the growth of mold. Unlike a humidity monitor, a humidistat is installed directly into HVAC systems.

Dew point, related to humidity, is also important as it’s the temperature point at which moisture gets saturated in air. Condensation usually occurs when air temperature is closer to the dew point and it can damage building materials, chemicals and any organic materials in the vicinity.

Humidity monitors can also be used to aid in preserving wooden musical instruments, humidors (used in preserving and storing cigars) and incubators to promote hatching. They’re also great for saunas, even if you may sometimes want to jack that humidity all the way up and get that hot, wet, jungle heat! When shopping for humidity monitors, you need to first decide on the type of hygrometer you want. They are categorized based on the technique they use to measure moisture levels. Also decide whether you want one with a thermometer or not.

This review focuses on digital humidity monitors built with electronic capacitive sensors that convert analog signals to digital signals. These sensors change their electrical variables in accordance with prevailing relative humidity values. Digital hygrometers are precise and compact for portable use. We hope that this review will help you choose the best humidity monitor for your specific area of application.
Considering what you can pay for a humidity monitor, they’re mostly affordably priced unless you want a high-end product for use in industrial areas. A good quality monitor with a reasonable accuracy range of 1% to 5% can cost anything below $30. Higher end humidity monitors can cost as much as $300; these high quality devices usually come with many features and cover extensive areas of up to 2000 square feet.

Whichever humidity monitor you opt for, expect the money you can pay for it to be influenced by its brand, quality, features and the functions it supports. Invest in a high quality monitor that you can use for a very long time as cheap humidity monitors are often of poor quality.
Humidity monitors are versatile devices that help both homeowners and individuals to monitor the levels of moisture indoors and/or outdoors. They can also measure temperature and the level of carbon dioxide in air. The devices are built with various features to support their functionality. Therefore, it’s important to consider the features your monitor comes with before making a purchase.

Here are the important features to look out for:
  • Highly accurate devices for precise readings
  • Recording of daily highs and lows in memory
  • multi-use to measure humidity, temperature, dew point and CO2
  • Outdoor or indoor use or both
  • Portable size
  • Mounting technique such as tabletop use, wall-mounting, etc.

Construction and Design
When shopping for a humidity monitor, consider the following factors:

Accuracy – buy a hygrometer with as minimal error rate as possible for increased accuracy.

Daily Lows and Highs – opt for a humidity monitor that records highs and lows daily in memory to help you analyze the data and to adjust accordingly.

Functional Versatility – decide whether you want a device that measures humidity only or includes other readings such as temperature, dew point and carbon dioxide.

Outdoor/Indoor – whereas some humidity monitors are designed for either outdoor or indoor use, others can be used both indoors and outdoors. Choose accordingly.

Size – opt for small and lightweight humidity monitors if you want to use them on the go.

Mounting Technique – a humidity monitor can be placed on a flat surface such as a desk using a stand, mounted on a wall or clipped onto a surface. Decide the type of mount or installation you want for your device depending on your intended application.

Battery Life – although some humidity monitors are electric, most are battery-powered. Choose one with a long battery life to save on the costs of replacing batteries.

Designs – pick the shape and color you want in your humidity monitor. Most of these devices come in circular and rectangular designs. Choose a color that enhances the look of your interior space if you plan to use your monitor indoors.

Memory a good humidity monitor can store high and low values daily for future reference. Choose one that can store the values for about three days and have a reset function to clear the values when you no longer need them.

Display - humidity monitors can either have LED or LCD screens. Choose the type and size you want accordingly. For a multi-use device, the display needs to be large enough to display all variable values.
Performance and Ease of Use
Whichever humidity monitor you opt for, ensure it’s multi-functional if there’s a need to monitor temperature and CO2, in addition to moisture levels. Your device should be easy to mount or install and easy to use. Opt for a durable and accurate monitor that you can use for a very long time before making replacements. Also ensure it has a warranty to protect you from manufacturing faults; a good humidity monitor is also made of high quality materials for high performance.
