ThermoPro TP49 Digital Hygrometer Indoor Thermometer-FAQs
How accurate is the ThermoPro TP49?
The TP49 offers high accuracy with temperature readings precise to ±1°F/°C and humidity readings within ±2–3%, making it reliable for indoor environments like homes, offices, and greenhouses.
Why is my ThermoPro TP49 showing incorrect readings?
Incorrect readings often result from weak batteries, improper placement, or exposure to moisture. Try replacing the batteries or moving the device to a stable environment. If the issue persists, the sensor may be faulty.
How can I tell if my digital thermometer or hygrometer is working correctly?
Take two readings a few minutes apart. If the results differ significantly or do not stabilize, recalibration or replacement may be needed.
How do I reset the ThermoPro TP49?
Remove and reinsert the batteries to reset the device. This often fixes display or measurement issues.
How can I improve the accuracy of my thermometer/hygrometer?
Keep the device clean, place it away from direct sunlight and vents, and calibrate regularly using methods such as ice-water (0°C) or boiling-water tests if applicable.
How often does the ThermoPro TP49 update readings?
The TP49 refreshes temperature and humidity data every 10 seconds for quick, real-time monitoring.
Where should I place the ThermoPro TP49 for best accuracy?
Place it in an open area, away from direct sunlight, heaters, humidifiers, or air vents to ensure stable and accurate readings.
How do I know if the hygrometer is working properly?
You can perform a salt test: place the device in an airtight container with a cup of salt and a few drops of water. After 6–8 hours, humidity should read close to 75%.
