Information on the most widely used ASTM standards within the materials testing industry
Model: UT2054, IEC60068-2
Constant temperature and humidity test chamber Equipment for testing the performance of materials in various environments and testing various materials heat-resistant, cold-resistant, dry-resistant, moisture resistance. Suitable for electronics, electrical appliances, mobile phones, communications, instruments, vehicles, plastic products, metals, food, chemical, building materials, medical, aerospace and other products for quality testing.
It is composed of three parts: heating, humidification and refrigeration. By means of a circulating motor mounted on the top of the box, the air is discharged into the box to achieve gas circulation and balance the temperature and humidity in the box. The data collected by the humidity sensor is transmitted to the temperature and humidity controller (microprocessor) for editing Processing, issuing control instructions.
