Weather instruments are tools used to measure and record various weather conditions and parameters. They are used to gather data on temperature, humidity, atmospheric pressure, wind speed and direction, precipitation, and other weather-related variables. Some common weather instruments include thermometers, barometers, hygrometers, anemometers, and rain gauges. Thermometers measure temperature, while barometers measure atmospheric pressure. Hygrometers measure humidity, anemometers measure wind speed and direction, and rain gauges measure precipitation. CPS carries brands such as Dwyer, Brunton, and Extech.
