What To Look For When Buying A Hygrometer

Although all hygrometers tell you the level of humidity in the area you have them installed in, certain hygrometers available are more robust, and come with additional features you can use to get the “best bang for your buck”.

Digital Or Analog – Deciding between a digital or analog should be based on your preference. Certain analog hygrometers can be built to last a long, long time. But during their lifespan, they need to be “tuned up” as well as calibrated. If you don’t want to deal with the hassle of an analog, then a digital hygrometer would be more appropriate. They come from the factory pre-calibrated and require zero maintenance.

Built-In Memory – Memory modules built into a hygrometers allow you to have an ongoing record of how humidity levels rise and fall, as well as what the average humidity level is across a specific period of time. This makes record keeping and calculations easier when trying to determine what affect humidity is having on a specific location, or group of locations (multiple hygrometers).

Built-In Thermometer – Having a thermometer that comes with your hygrometer in one convenient package can help prevent instances of lost equipment. The more equipment you have operating solo, recording only a single type of readout, the more chance you have of misplacing it.

Built-In Alarm – Knowing the moment humidity levels go above or below a certain range can be very useful, especially when you’re spending time in other areas, away from the hygrometer itself.

Backlit Display – Being able to see the digital readout on your hygrometer isn’t possible at night unless you have a backlit display. This feature can save you the hassle of having to turn on the light every time you want to see a readout in a dimly lit area.

Slim Profile – A hygrometer that’s big and bulky doesn’t do anything to ensure you’ll be able to fit it anywhere. A slim profile hygrometer will fit in tight spaces, and only takes up a few inches of space no matter where you put it.

Affordable Price Tag – Affordability when it comes to hygrometers is important because they’re simplistic instruments. There’s no need to overspend on an overpriced deluxe brand name, when the great majority of the cheaper priced ones are accurate and well-built as it is.

Although it’s possible to live in your home without a hygrometer to gauge the humidity levels, you have the best chance of achieving and maintaining good health by installing a hygrometer. This way, you can keep a healthy level of humidity consistently, and be alerted the moment it rises/falls outside of the desired range. Many people miss out on exactly how much better it feels to know that humidity levels around valued possessions is at an appropriate level. Areas that are too moist or too dry can have a seriously degrading effect on valuable items, and with a hygrometer installed, you can always know for sure that you’re doing your best to protect your health and wealth.
