A temperature and humidity meter is an instrument that can simultaneously measure environmental temperature and relative humidity. It is a fundamental tool for monitoring environmental conditions and is widely used in various scenarios such as daily life and production.

In terms of types, the common ones are pointer type and electronic (numerical) type. Pointer type relies on mechanical structure operation, does not require power supply, has intuitive readings, and is suitable for daily scenarios with low precision requirements; Electronic (digital) methods collect data through sensing elements and display it on a screen, resulting in higher measurement accuracy. Some also have functions such as alarm and data recording, which can meet the high accuracy requirements of data in scenarios such as laboratories and pharmaceutical warehouses.

Its core feature is convenience and practicality. The volume is usually small and can be flexibly placed or hung indoors, in warehouses, greenhouses, and other places. Whether it's mastering indoor comfort in the home, adjusting the use of air conditioning and humidifiers; Monitoring greenhouse temperature and humidity in agriculture to ensure crop growth; Or in industrial production, controlling the workshop and warehouse environment to ensure product quality, temperature and humidity meters can provide timely and critical temperature and humidity data support.
