The Best Digital Humidity and Temperature Monitor

Monitoring the humidity and temperature of your house or condo is crucial to maintaining a healthy and comfortable atmosphere in your home. If you happen to live in a place with low humidity content, you could get a humidifier in order to maintain proper humidity levels throughout your rooms. But humidifiers don’t include humidity monitoring tools, so you need to know when you should turn them on or shut them down.

Too little humidity could cause irritation in your nasal tract, cracking in your lips, skin allergies, etc. Too much humidity means that your skin will feel sweaty and it could result in great discomfort, especially during the nights. You may also think that temperature monitoring is not that important, since you may already have tools for that, such as your thermostat.  Digital hygrometers (home temperature and humidity monitoring devices) are more accurate at measuring temperatures, and include features such as temperature and humidity alarms, constant monitoring, data storage, etc.

They also include calibration to reduce error factor, and are a great asset to any home located located in areas that experience extreme climate conditions.

Choosing the Best Digital Humidity and Temperature Monitor

So how do you choose a good hygrometer for your home? It is not very difficult if you only look for the basics such as temperature and humidity monitoring, because pretty much all the personal hygrometers in the market can do that. But quality and accuracy is what you should be looking for. For instance, a good hygrometer will be able to measure data with an accuracy of +/- 3% accuracy or lower, whereas a cheaply built model will hover around +/- 10% accuracy.

Also, choose a hygrometer that can be calibrated to improve accuracy, a non-calibrated unit’s accuracy is bound to vary over time. Also, look for a model with a large and easy to read display. It should also include low, medium, and high temp/humidity scales and should be able to alert you via an alarm system when the temperature or humidity crosses a certain point. Alarm systems can come in handy when you plan to purchase a hygrometer for your personal miniature greenhouse, sauna, or baby room.

Make sure your device can record both the daily low’s as well as high’s, hygrometers capable of storing data records for several days are even better, in case you want to monitor your homes humidity and temperature levels over a certain period of time. Also, don’t forget that a good hygrometer should be easy to use and needs to have a long battery life (approx. one year). With all these points in mind, you now know what a good personal hygrometer should be like and I hope you have enjoyed reading our review to find the best digital humidity and temperature monitor on the market today.
