Humidity also plays a factor in heat stroke and heat exhaustion. As well as affecting people, too much or too little humidity can affect your possessions. Too little humidity can dry out and damage furniture. In contrast, too much humidity can cause moisture stains, condensation, swelling, and mold.

Large Digits Display The indoor thermometer comes with the clear display featuring large digits, you'll only need a glance from across the room to easily get the readout. 3 Placement Options The home thermometer is designed with hanging hole, magnetic back and tabletop stand, easily place the hydrometer digital anywhere. Review: Small Digital Hygrometer - I’ve been using the ThermoPro TP49 Small Digital Hygrometer Indoor Thermometer for a while now, and it does the job without any fuss. It’s small, simple, and easy to place anywhere thanks to the stand, magnet, or wall slot on the back. The screen is clear and the numbers are easy to read at a glance, which is really handy. I also like the little comfort smiley icons – they give a quick idea of whether the room feels too dry, too humid, or just right. The readings seem accurate enough and update quite often, so you can keep an eye on changes without waiting long. For the price, it feels like good value. It’s not fancy, but it works well for keeping track of temperature and humidity at home or in the office. Review: Great Value, Accurate Monitor - A family member asked me advice on humidity and the best monitor to display this in their home. Research suggested the ThermoPro range were very popular and importantly accurate. Just a basic hygrometer was needed showing the humidity and temperature, this model fits that bill. Inside the box is the hygrometer, battery and instruction booklet. The hygrometer is nice and small however the font of the information on the display is bigger than some on larger displays so for people who maybe have issues reading this is ideal. The font is clear to read. There is a stand on the back of the unit and you can switch between Centigrade and Fahrenheit being displayed on screen. If the humidity is in the normal range a small face on screen will display this as added info. When I set it up I compared it to two other hygrometers I have and it was close to one but a small difference to the other. The other monitor is a cheap, basic model so the ThermoPro appears accurate as expected. So overall this is a great little hygrometer with excellent functionality at a very good price. ## Features - Comfort Level Indicator: The home indoor thermometer has 3 types of smile icons that simultaneously display different temperature and humidity levels, it allows you to keep an eye on your health and comfort at home: wet, comfort, dry at a glance. - Accurate and fast response: The indoor air thermometer allows air flow to flow through the ventilation holes and gives you fast and accurate data over time, it measures the temperature range from -50 to 70 degrees Celsius and humidity ranges from 10 to 99 percent relative humidity, so you can adjust the heating or humidifier base on temperature and humidity readings.

Still very easy to read. If you are worried about it shining at night, it doesn't. My unit is white however (not black), but is a TP-49. **Q: How do I register the product for the extended warranty?** A: This is what they mention in the product description:2+2 YEARS WARRANTY! REGISTER your nursery thermometer after purchase and INCREASE YOUR WARRANTY COVERAGE FROM 2 YEARS TO 4 YEARS **Q: Can this be used in a greenhouse?** A: Hi Aaron.... whilst the Thermopro is considered an indoor thermometer - I cannot see a reason why it can’t be used in a greenhouse, as the temp range is -50 to 70c. It’s a great device! **Q: What is the size of this? Various reviews mention it being small but that is not helpful.** A: Hello R Robinson... The overall dimensions are W55mm x L65mm. Whilst the physical dimensions of the thermometer may seem “small”, don’t be disheartened.... the numerical digits are large (15mm) and very easily read. It’s a good purchase! ## Customer Reviews ### ⭐⭐⭐⭐⭐ Small Digital Hygrometer *by G***L on 21 March 2026* I’ve been using the ThermoPro TP49 Small Digital Hygrometer Indoor Thermometer for a while now, and it does the job without any fuss.

The thermometer comes in a small box and includes a AAA battery (which is really handy!), and finally there is a small magnetic on the back which makes it really easy to stick to the fridge. The magnetic is really strong too. I think my only negative comment about this thermometer is that it is not a smart thermometer. We frequently have to stay with my parents when the temperature heats 25 degrees outside as it is always around 10 degrees hotter indoors. I wouldn't have known this had I not have ordered this product. So now we know if it's predicted to be a certain temperature outside then we need to stay elsewhere for a few days. Both the thermometer and humidity levels seem to be working correctly as I double checked with a different brands thermometer. The smiley faces are really helpful in determining moisture levels too so you always know when to put your dehumidifier on! At £5.93 (at time of purchase) this is an incredibly accurate and fully working piece of kit. I would argue that given the change in British summers over the last couple of years, this is an important and essential item that all households should have! ## Frequently Bought Together - ThermoPro TP49 Small Digital Hygrometer Indoor Thermometer Ambient Thermometer Temperature Monitor and Humidity Meter for Home Office Comfort Reptile Thermometer - Homvana Humidifier for Bedroom, 3.6L Cool Mist for Large Room Office, 360° Rotatable 34H Last, Night Light Auto Mode, Quiet 16dB Humidifiers for Baby, Essential Oil Diffuser, Plants, Nursery - ThermoPro TP50 Digital Thermo-Hygrometer Indoor Room Thermometer with Recording and Climate Indicator for Room, Climate Control Monitor --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/162933314-thermopro-tp49b-digital-mini-thermo-hygrometer-thermometer-hygrometer-indoor-temperature](https://www.desertcart.us/products/162933314-thermopro-tp49b-digital-mini-thermo-hygrometer-thermometer-hygrometer-indoor-temperature) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-20*
