Definition and core functions

A constant temperature and humidity test chamber is a device that can maintain a constant temperature and humidity, usually consisting of a sealed box and a control system. Its core function is to ensure that the environmental conditions inside the test chamber are always near the set values through efficient heating and cooling systems, precise humidity control systems, and real-time monitoring sensors. This device can simulate various climatic conditions, such as high temperature, low temperature, high humidity, low humidity, etc., to evaluate the performance and durability of products in different environments.

Material constant temperature and humidity test chamberworking principle

The working principle of the constant temperature and humidity test chamber is based on the excellent PID (proportional integral derivative) control algorithm, and precise temperature control is achieved through the following components:

• Heating system: Usually uses nickel chromium alloy electric heating wire or PTC heating element.

• Refrigeration system: Mechanical compression refrigeration is commonly used, and models use cascade refrigeration or liquid nitrogen assisted refrigeration.

• Temperature sensor: PT100 platinum resistance or thermocouple, with an accuracy of ± 0.1 ℃.

Humidity control is achieved through the following methods:

• Humidification system: Generally, boiler humidification or ultrasonic humidification technology is used.

• Dehumidification system: using refrigeration dehumidification or desiccant dehumidification.

• Humidity sensor: Capacitive polymer film sensor with an accuracy of ± 1% RH.
