General description The Wall Mounted Household Thermometer Hygrometer is a high-accuracy three-in-one meteorological station that functions as a thermometer, hygrometer, and barometer. It is designed to provide reliable measurements of air pressure, temperature, and humidity, making it an essential tool for monitoring indoor and outdoor weather conditions. Technical specifications Model No.: THB9392 Measurement Range: Pressure 960~1060 hPa, Temperature -30~50 °C, Humidity 0~100% Rh Resolution: 1 hPa, 1 °C, 2% Rh Accuracy: +/- 5 hPa, +/- 2 °C, +/- 5% Rh (for 40~70% Rh) Unit Size: Ø13 x TH 4.1 cm Weight: 0.13 kg Usage The white pointer is a manual contrast pointer to indicate changes in air pressure, not an automatic measurement. It is important to note that air pressure does not change daily; significant changes in weather will affect pressure readings. The weather forecast function is based solely on air pressure and may not be accurate in all locations, especially at high altitudes.
