The chamber adopts high stability temperature measuring body, Chinese and English touch screen, equipped with computer interface control, which can simulate different environmental conditions such as high temperature, high humidity, high temperature, low humidity, low temperature, high humidity, high temperature and low temperature.
Highly accurate programming control and fixed point control system so that it is easy to operate and learn, providing good test performance.
Ordinary high and low temperature test chambers generally refer to constant high and low temperature test chambers, which are controlled by setting a target temperature and the ability of the test chamber to automatically constant temperature to the target temperature point.
The control method of the constant temperature and humidity test chamber is similar. Set a target temperature and humidity point. The test chamber has the ability to automatically adjust the temperature to the target temperature and humidity point.
The alternating test chambers all have the function of a constant test chamber, but the manufacturing cost of the alternating test chamber is higher, because the alternating test chamber needs to be equipped with a curve automatic recording device and a program control device, and the temperature of the test chamber in the working chamber must be solved.
In the case of high temperature, the refrigerator is turned on. Therefore, the price of the alternating test chamber is generally 20% higher than the price of the constant test chamber.
The high and low temperature alternating test chamber has the program of setting one or more high and low temperature changes and circulations. The test chamber has the ability to complete the test process according to the preset curve, and can be accurate within the range of large temperature rising and cooling rate capabilities.
By controlling the rate of temperature rise and temperature drop, the temperature rise and temperature drop rates can be controlled according to the slope of the set curve. Similarly, the high and low temperature alternating heat and humidity test chamber also has a preset temperature and humidity curve, and the ability to control according to presets.
