Museums hold many valuable artifacts and documents because over time these objects are inevitably threatened by the environment, one of which is inappropriate water vapor in the air.
High humidity can lead to disruption of the moisture balance in the air, growth of bacteria and corrosion of objects. Temperature and humidity must be reasonable and stable to keep artifacts, documents, etc. in optimal condition.
Temperature and humidity requirements vary from collection to collection.
The national standards for temperature and humidity in museum storerooms are as follows:

Accurately control the temperature and humidity of the environment to provide a protective umbrella for museum artifacts and documents.
PARKOO constant temperature and humidity machine can automatically control the temperature and humidity through the real-time monitoring of temperature and humidity sensors, according to the changes in environmental humidity, accurately controlling the humidity at ±3% and the temperature at ±0.5℃, which is a perfect solution to the museum's temperature control and dehumidification requirements.
