TP49 vs TP55 vs TP359: Which Hygrometer Is Right for You?
288 Comments
Indoor temperature and humidity can affect more than just how comfortable your home feels. Humidity that is too high can contribute to condensation and a damp environment, while very dry air can make your skin, nose, and throat feel uncomfortable. Keeping an eye on indoor conditions can help you make better decisions about heating, cooling, ventilation, and humidity control.
But not everyone needs the same level of monitoring.
Some people simply want to know the temperature and humidity in a room at a glance. Others want to see how much those conditions have changed throughout the day. And if you want to monitor your home while you're away, keep historical data, or receive alerts, a Bluetooth hygrometer can be much more useful.
TempPro develops many hygrometers designed for different monitoring needs. In this guide, we'll compare the TempAir CORE TP49, TempAir CORE TP55, and TempAir ELITE TP359 to help you choose the right one for your home.

- TempAir ELITE TP359: Monitor conditions remotely and manage your data.
Let's take a closer look at which one makes sense for you.
TempAir CORE TP49
Best for: simple temperature and humidity monitoring
Sometimes, simple is exactly what you need. The TempPro TempAir CORE TP49 Indoor Thermometer Hygrometer is designed for people who want an easy way to check the current temperature and humidity without extra features or a complicated setup.
You can place it in a bedroom, living room, office, nursery, or another indoor space and quickly check the current conditions.
Who Should Choose the TempAir CORE TP49?
A basic hygrometer can actually be more convenient for everyday use when you don't need advanced features. There's no need to open an app, connect to your phone, or review charts. Just look at the display and see the current temperature and humidity.
TempAir CORE TP49 is a good choice if:
- You only need current temperature and humidity readings.
- You prefer a simple, straightforward device.
- You don't need historical temperature data.
- You don't need to monitor conditions from your phone.
- You want an affordable option for monitoring multiple rooms.
For example, if you're wondering whether your bedroom is too warm or too dry before going to bed, you don't necessarily need a smart monitoring system. A simple digital hygrometer can give you the information you need in seconds.
TempAir CORE TP55
Best for: tracking temperature and humidity changes
What if the current reading isn't enough?
For example, your room may be 72°F right now, but was it 78°F earlier today? Did the humidity increase overnight? Is the room getting more humid when the air conditioner isn't running?
That's where the TempPro TempAir CORE TP55 Digital Indoor Thermometer & Hygrometer becomes more useful. It lets you view high and low temperature and humidity records, giving you more insight into how conditions have changed.
Temperature and humidity naturally change throughout the day.
For example:
- A bedroom may become warmer during the afternoon.
- Humidity may rise after cooking or showering.
- A room may become cooler overnight.
- Running heating or air conditioning can change indoor humidity.
- A basement may have noticeably different humidity levels from the rest of the house.
Looking at only the current reading gives you a snapshot. High and low records give you a little more context.
TempAir CORE TP55 is a good fit if:
- You want more information than a basic hygrometer provides.
- You want to see high and low records.
- You want to understand daily temperature and humidity changes.
- You prefer checking information directly on the device.
- You don't need Bluetooth or phone-based monitoring.
TempAir ELITE TP359
Best for: smart and remote temperature & humidity monitoring
If you want to monitor indoor conditions from your phone, review historical data, export measurements, or receive alerts, the TempPro TempAir ELITE TP359 Bluetooth Indoor Hygrometer Thermometer is the more advanced option.
TempAir ELITE TP359 connects to your smartphone through Bluetooth, allowing you to monitor temperature and humidity without constantly checking the device itself. This can be useful when you're working in another room or want to keep track of conditions over time.
Instead of walking over to the hygrometer every time you want to check the readings, you can use your phone to review the information.
TempAir ELITE TP359 doesn't sacrifice the convenience of seeing high and low readings. You can use the device to monitor current conditions while also keeping track of temperature and humidity highs and lows. This makes TempAir ELITE TP359 useful for people who want both at-a-glance monitoring and more detailed information.
One of the biggest advantages of a Bluetooth hygrometer is the ability to work with your data over time. TempAir ELITE TP359 lets you review temperature and humidity history and export your data when you need it.
You could use historical data to:
- Understand your indoor temperature and humidity patterns.
- Compare conditions between different periods.
- Investigate recurring humidity changes.
- Monitor a room over a longer period.
- Keep records for a specific project or environment.
For example, if you notice that a room feels unusually humid every morning, looking at historical readings can help you determine whether that is an occasional change or a recurring pattern.
Another advantage of smart monitoring is that you don't have to constantly check your readings. TempAir ELITE TP359 supports alerts, helping you stay informed when temperature or humidity conditions reach the limits you've set. This can be especially useful when you're monitoring a space where changes matter even when you're not actively looking at the display.
