Temperature Humidity Test Chamber ≤ 2.0 ℃ Temperature Deviation
Temperature Humidity Test Chamber Application
DGBELL’s Temperature Humidity Test Chamber is able to simulate a wide range of temperature and humidity environment conditions for testing various products and components. It is widely used for basic thermal cycling tests and accelerated stress tests. We provide 6 standard models, test cabinet from 80L to 1000L, customized size is also available.
The temperature humidity test chambers use imported temperature controllers to control temperature and humidity. Programmable controllers can be used to set a variety of parameters. The temperature and humidity are directly displayed digitally, and the operation of the constant temperature test chamber is convenient.
The equipment is accurately measured by a temperature and humidity sensor and controlled by an industrial programmable controller. It can automatically adjust the humidity in the temperature and humidity verification chamber, process the humidity verification data and print the results. With high control and test accuracy, it can provide continuous and repeatable humidity measurement.
It is suitable for product testing in scientific research units such as aerospace, metrology, petrochemical industry, pharmaceutical engineering, agricultural research, life science, electronic appliances, etc.
