- Humidity Range: 10% to 99%.
- Temperature Unit: Selectable between °C and °F.
- Temperature Resolution: 0.1 °C/°F.
- Humidity Resolution: 1%.
- Comfort Level Display: Indicates DRY (humidity below 30%), COMFORT (humidity between 30% to 60%), or WET (humidity above 60%).
- Design: Fully wireless, suitable for tabletop placement, wall mounting, or magnetic mounting.
Operation
Low Battery Indication: When the low battery indicator is displayed, replace batteries promptly. Low batteries can reduce touch button sensitivity.
Touch Buttons:
- °C/°F: Tap to switch between Celsius (°C) and Fahrenheit (°F) temperature display.
- < >: Tap to turn the backlight on or off.
- ALL TIME/24 HRs: Tap to view the maximum and minimum recorded temperature and humidity. Select "ALL TIME" for recorded values since the last reset, or "24 HRs" for values within the last 24 hours. In "24 HRs" mode, readings automatically reset every 24 hours. Press and hold the "ALL TIME/24 HRs" button for 3 seconds to clear all recorded maximum and minimum values.
Backlight: Press the key to activate the backlight. Press again to turn it off. The backlight will automatically turn off after 15 seconds of inactivity.

Frequently Asked Questions (FAQ)
About Accuracy:
The hygrometer offers high accuracy for its price range. For higher accuracy (±1%), laboratory devices costing over $1000 are required. Compared to competitors, ThermoPro devices are accurate to within ±3%, while others are ±5%. For best accuracy testing, compare two identical devices; readings should be within ±6% of each other.
About Humidity Range: 10%~99%
While the hygrometer is accurate for its price, it displays 10% for humidity levels below 10% (e.g., 5% actual humidity shows as 10%). Only expensive laboratory equipment can measure humidity below 10%. No device on the market can measure humidity below 5%.
