The principle of constant temperature and humidity test chamber

constant temperature and humidity test chamber is also called constant temperature and humidity test machine, constant temperature and humidity test chamber, constant temperature machine or constant temperature and humidity chamber. It is suitable for testing the quality of electronic, electrical, communication, instrumentation, vehicles, plastic products, metal, food, chemistry, building materials, medical treatment, aerospace and other products

working principle:

constant temperature and humidity test chamber is composed of temperature regulation (heating and cooling) and humidification. Through the rotating fan installed on the top of the box, the air is discharged into the box to realize gas circulation and balance the temperature and humidity in the box. The data collected by the temperature and humidity sensor inside the box can avoid buying instruments blindly or buying instruments when they are displayed to customers and transmitted to the temperature and humidity controller (micro information processor) for processing, and the temperature and humidity regulation instructions are issued through the air heating unit The condensation pipe and the heating evaporation unit in the water tank are completed together

the temperature regulation of the constant temperature and humidity box is to collect data through the built-in temperature sensor in the box, adjust it by the temperature controller (micro information processor), connect the air heating unit with the production center to increase the temperature or adjust the refrigeration solenoid valve to reduce the temperature of eelcee company on various preforms with different material combinations and shape configurations, so as to achieve the required temperature control. The temperature regulation of the constant temperature and humidity box is to collect data through the built-in temperature sensor, adjust it by the humidity controller (micro information processor), turn on the heating element of the water tank, increase the humidity in the box by evaporating the water in the water tank, or adjust the refrigeration solenoid valve to achieve the dehumidification effect, so as to achieve the required humidity control

the constant temperature and humidity box is equipped with multiple protective measures; Under the condition of setting the maximum allowable safe temperature, the temperature system is equipped with an over temperature protector, and the air heating element can automatically power off when the rotating fan stops; The humidification system can stop power supply as the water level of the humidification tank decreases; The refrigeration system also stops working with the increase of the temperature of the box due to a series of chain reactions (more than 40 ℃) caused by overload or the increase of humidity

the device has the following characteristics:

1 The appearance design is simple and beautiful, the installation position of each part is reasonable, and the electrostatic spraying color can meet the needs of customers

2. The matching of laboratory real questions requires an ultra wide temperature control range

3. Adopt the original high-precision programmable temperature controller from Japan or South Korea, and operate with a 7-inch true color touch screen

4. Chinese/English liquid crystal display, equipped with more than 10m/100m telo interface, with free operating software
