High and low temperature alternating humidity test equipment humidity test chamberBox structure:

lThe equipment is made of high-quality steel materials both inside and outside, and is processed and formed using the latest domestic processing equipment,Reasonably designed and durable.On the premise of complying with national standards and ensuring stable performance in all aspects, the equipment is more practical and easy to control. Moreover, the device has the characteristics of easy installation, simple operation, and basically no need for daily maintenance.

lThe equipment casing is made of stainless steel plate processed by CNC machine tools, which is easy to clean, resistant to aging, and has the characteristics of durability, wear resistance, corrosion resistance, etc.

lThe inner liner isSUS304, 8k mirror stainless steel plate, bright, beautiful, and corrosion-resistant.

lthermal insulation materialPolyurethane foam is added with high-density aluminum silicate fiber cotton. Aluminum silicate fiber cotton has the characteristics of high temperature resistance and low heat transfer coefficient compared to similar glass fiber cotton. The insulation thickness is 100mm to ensure that the temperature inside the test room will not be transmitted to the outside of the equipment, making the test temperature more accurate.

lInstall an observation window at the center of the test chamber door to observe changes in the indoor sample.The observation window adopts three-layer insulated tempered glassThe inner and outer double-layer laminated conductive film has the advantages of transparency, heat insulation, and is not prone to steam frosting. It is equipped with high-quality lighting to assist in observing the test conditions inside the test chamber when there is insufficient light.

linternal circulation systemLong shaft motor with high temperature and high humidity resistance from Taiwan, China, China, and aluminum multi blade impeller with high temperature and high humidity resistanceTo achieve forced convection and vertical diffusion circulation, ensuring uniform and constant temperature and humidity in the laboratory.

lA double-layer high tensile silicone sealing strip that is resistant to high and low temperatures is used between the test chamber door and the box body to ensure the sealing of the testing area. The main door plate is made of stainless steel, which is beautiful, durable, and uses a non reactive door handle, making it easier to operate, durable, and not easily damaged.

lLead test hole(On the left side of the machine) can be used for external testing of power or signal lines (with a diameter of 50mm, one is standard),If the aperture and number of holes need to be increased, they can be requested at the time of ordering）.

lThe refrigeration system of the equipment is installed at the bottom, and the compressor adopts a French Taikang brand fully enclosed compressor to ensure that the temperature is reduced to the required value within the specified time.

lHigh quality fixable installation at the bottom of the machinePU activity wheels can easily move and fix the machine.

lThe control part of the equipment is designed on the right side of the device, with temperature controllers, control switches, etc. distributed, making it easy to operate, simple, and maintain.
