Selection of Control Method for Simulated Climate Chamber

There are two types of temperature and humidity environmental test chambers: constant test chambers and alternating test chambers.

Generally speaking, high and low temperature environmental test chambers refers to constant temperature, and their control method is to set the target temperature, and the test chamber has the ability to automatically maintain constant temperature to the target temperature point.

The control method of the constant temperature and humidity environmental test chamber is similar, setting the target temperature and humidity point, and having the ability to automatically maintain constant temperature to the target temperature and humidity point.

The high and low temperature alternating test chamber can set one or more high and low temperature changes and cycle programs.

The test chamber has the ability to complete the test process according to the preset program, and can accurately control the heating and cooling speed within the maximum temperature rise range and the cooling speed ability, that is, the heating and cooling speed can be controlled according to the slope of the set curve.

Of course, the alternating test chamber has the function of a constant test chamber, but the manufacturing cost of the alternating test chamber is relatively high. Because the alternating test chamber needs to be equipped with automatic curve recording equipment, program controllers, and problems such as opening the chamber at high temperature.
