Before buying a hygrometer, it’s essential to consider how its design and specifications impact its performance and user experience. Here are four factors to think about before making a purchase.
Digital vs. Analog
Hygrometers are offered in both digital and analog formats. Digital hygrometers have built-in screens that display humidity readings in numbers. Digital hygrometers are easier to read than their analog counterparts, though they’re typically more expensive. While digital devices are more popular, some homeowners select analog models for their large clock-like face and minimal maintenance.
Many digital hygrometers display additional weather readings on their LCD screens. For example, the ThermoPro Jumbo Digital Touchscreen Hygrometer displays the indoor temperature and humidity and the daily lows and highs for temperature and humidity.
While analog hygrometers don’t require power, digital hygrometers do. Most models, such as the ThermoPro Digital Hygrometer, are powered by AAA batteries, allowing them to move around your home.
Some hygrometers offer push notifications that help homeowners quickly identify spikes in indoor temperatures and humidity levels. For example, the Govee Digital Hygrometer connects to your smartphone and sends alerts when levels break a preset range. Without remote connection, homeowners have to periodically check their hygrometers to ensure that readings meet their standards.
Frequently Asked Questions
What humidity level is ideal for indoor environments?
To keep your indoor area comfortable, ensure that your hygrometer displays between 30% and 50% humidity. If you struggle to keep the humidity within that range, consider a dehumidifier.
What does a humidity reading mean?
Humidity is a measurement of the amount of moisture the air is holding. For example, if the humidity is 33%, the air is holding about a third of the moisture it can at that given temperature.
How does temperature impact humidity?
Warm air can hold more moisture, which is why the summer months are typically more humid than the winter months.
