Comprehensive 3in1 weather monitoring. The 130 mm diameter 3in1 Weather Station combines a thermometer, hygrometer and barometer with mechanical movement for accurate ambient temperature (30 to 50 C), humidity (0 to 100% RH), and atmospheric pressure (970 to 1050 hPa). Battery operation enables reliable home weather forecasting. Accurate environmental readings. Mechanical operation delivers temperature accuracy of ±2 C, humidity accuracy of ±5% RH at 40 to 70% RH, and pressure accuracy of ±5 hPa within 970 to 1040 hPa. These readouts support informed decisions for heating, cooling, or ventilation in home environments. Durable metal construction. The unit features a long lasting aluminium body with a refined finish designed to withstand indoor environmental variations while maintaining precise readouts. Built for dependable service life in home and garden installations. Detailed weather trends display. The home style barometer provides clear trends in air pressure, humidity, and temperature, making complex climatic changes easy to interpret for indoor climate control or hobbyist meteorological observation. Practical use scenarios Home comfort and HVAC: Place in the living room to guide thermostat settings, window management, and humidity control for consistent comfort. Greenhouse or indoor garden: Monitor temperature and humidity to maintain growing conditions without relying on power. Workshop or garage: Track conditions to protect tools, materials, and work environment from unwanted temperature and humidity swings.
