3a Current Temperature Humidity Chamber 800 Constant Temperature And Humidity Chamber

Product introduction:

The constant temperature and humidity test chamber, also known as "programmable constant temperature and humidity test chamber, constant temperature and humidity chamber", is the same series as "high and low temperature alternating heat and humidity test chamber". It is an essential test for aviation, automobile, home appliances, scientific research and other fields. Equipment used to test and determine the parameters and performance of electrical, electronic, and other products and materials for high temperature, low temperature, alternating damp heat, or constant temperature environment changes.

working principle:

The constant temperature and humidity test chamber consists of two parts: temperature adjustment (heating, cooling) and humidification. Through the rotating fan installed at the top of the box, the air is discharged into the box to realize the gas circulation, balance the temperature and humidity in the box, and the data collected by the temperature and humidity sensors built in the box is transmitted to the temperature and humidity controller (micro The information processor performs editing processing, and the temperature adjustment and humidity adjustment command is issued, and is completed by the air heating unit, the condensation tube, and the heating evaporation unit in the water tank.

The constant temperature and humidity chamber temperature adjustment is through the built-in temperature sensor of the box, collecting data, adjusting by the temperature controller (micro information processor), turning on the air heating unit to increase the temperature or adjusting the cooling solenoid valve to reduce the temperature inside the box. The temperature required for control is reached. The constant temperature and humidity chamber humidity adjustment is carried out by the built-in humidity sensor, collecting data, adjusting by the humidity controller (micro information processor), connecting the water tank heating element, and increasing the humidity in the tank or regulating the cooling by evaporating the water in the water tank. Solenoid valves are used to achieve dehumidification to achieve the desired humidity.

The constant temperature and humidity chamber is provided with multiple protection measures; the temperature system is equipped with an over-temperature protector under the condition that the maximum safe allowable temperature can be set, and the air heating element can be automatically powered off when the rotating fan stops; the humidification system can follow the humidification tank water level The power supply is reduced and stopped; the refrigeration system also stops working as the temperature of the cabinet rises (over 40 ° C) or the humidity increases.
