General description The Thermometer Hygrometer Barometer Three-in-One Weather Station is a high-accuracy instrument designed to measure atmospheric pressure, temperature, and humidity. It features a manual white pointer for tracking air pressure changes, allowing users to anticipate weather conditions based on pressure variations. Technical specifications Model #: THB9392 Measuring Range: 960~1060 hPa (pressure), -30~50 °C (temperature), 0~100% RH (humidity) Resolution: 1 hPa (pressure), 1 °C (temperature), 2% RH (humidity) Accuracy: +/- 5 hPa (pressure), +/- 2 °C (temperature), +/- 5% RH (40~70% RH) Unit Size: Ø13 x TH 4.1 cm Weight: Approx. 0.13 kg Usage The white pointer serves as a contrast pointer to indicate air pressure trends. Weather forecasting is based on air pressure changes, which may not always reflect actual weather conditions due to altitude and terrain differences. For high-altitude locations, ensure that the air pressure remains within the measuring range (960~1060
