Product Features
●Air supply channel and refrigeration unit adopt integral design.
●The slope is used for transporting heavy object into the test chamber.
●Large observation window makes it convenient for operator to observe the test sample inside the chamber.
●Lead holes are available on the two sides of the equipment, convenient for placing the testing apparatus, leads and others on the two sides of the equipment.
●The inner chamber is made by SS304 stainless steel; the external chamber is made by SECC, and its surface is treated by electrostatic powder coating.
●Modularized Refrigerating system, waterway system and the electrical control system for safety and ease of maintenance.
●Air vents are in the chamber for uniformity in temperature inside the chamber and the temperature and humidity can become constant at a much faster speed. The angle of guide vane can be adjusted freely, effectively ensuring the uniformity inside the chamber.
