An allinone indoor weather station in a 130 mm aluminum body that combines thermometer, hygrometer, and barometer in a single mechanical instrument. It measures temperature from 30 to 50 C, humidity from 0100% RH, and atmospheric pressure from 9701050 hPa, with accuracy of ±2 C, ±5% RH, and ±5 hPa respectively. Power operation: The mechanical movement design runs without an external power source. It provides continuous 24/7 readings through precise analog displays and will not fail during power outages. No batteries or electricity are required, and there are no ongoing maintenance costs. Multiparameter monitoring: Simultaneously tracks temperature, humidity, and barometric pressure to give a complete view of indoor air conditions and to help predict weather changes based on atmospheric pressure trends. Durable, traditional design: Built with sturdy aluminum construction and mechanical components, providing reliable, maintenance operation and readable analog displays. Home weather forecasting: Analyzes barometric pressure changes to forecast upcoming weather patterns, helping you plan daily activities and adjust indoor climate control based on ambient conditions and humidity.
