How to choose a suitable high and low temperature damp heat test box?

Products mainly involved in aerospace, military equipment, electrical and electronic, motorcycles, chemical and medical, postal and telecommunications, industrial and mining enterprises, scientific research and education, steam quality inspection and measurement, ship and railway enterprises and institutions and universities and research institutions.

Constant temperature and humidity test chamber

Commonly, there are two control methods: fixed value operation and programmable operation.

Constant temperature and humidity test chambers with fixed value operation are also commonly called

High and low temperature damp heat test chamber

The control method is: setting a target temperature and humidity, and the test box has the ability to automatically maintain constant temperature and humidity to the target temperature and humidity point.

Programmable constant temperature and humidity test chamber is also called

High and low temperature alternating heat and humidity test chamber

The control mode is multi-stage programming control: it has the ability to preset temperature and humidity curves, and control according to presets, and can be set in multiple stages. The test chamber has the ability to complete the test process and cycle according to the preset curve, and can accurately control the rate of temperature rise and decrease in the range of maximum temperature rise and decrease rate capability, that is, the temperature rise and decrease rate can be controlled according to the slope of the set curve. .

Therefore, the programmable high temperature and humidity test chamber can be operated at a higher cost because it needs to be equipped with a program controller, and it is also necessary to solve the problem that the test chamber is turned on when the temperature in the working chamber is high. The price is 30% higher than the price of the test box. Customers should choose the corresponding constant temperature and humidity test chamber according to their own test conditions, in order to obtain the most cost-effective equipment.
