The Langlun instrument cold and hot shock test chamber has the following performance characteristics: 1. This equipment is divided into three box and two box types, which can be selected according to usage needs; 2. The three box type is divided into three parts: high temperature zone, low temperature zone, and normal temperature/testing zone. It adopts a unique thermal insulation structure and thermal storage effect. During the test, the test object is stationary, and the cold and hot air path switching method is used to introduce it into the test sample for cold and hot shock testing; 3. The two box type is divided into a high temperature zone, a low temperature zone, and a lifting basket. During the test, the test object is placed inside the lifting basket, and the cylinder moves the basket to move the test object into the high temperature and low temperature zones for thermal shock testing; 4. The interior of the box is made of SUS304 stainless steel plate welded as a whole, which is corrosion-resistant and rust proof; The exterior adopts SECC steel plate baking paint (color number can be customized) to increase the appearance texture and cleanliness. 5. Scientific and reasonable design structure, good internal circulation of cold and hot air, and uniform temperature distribution. 6. All components of the equipment are selected from international and domestic brands, with stable and reliable performance. 7. Multiple safety protection devices ensure the safety of users and products.
