Constant temperature and humidity testing machine, high and low temperature testing machine, high and low temperature humidity and heat alternating testing machine

product description:

Test various metal materials and products under natural or artificial environment, the mutual change of various temperatures and humidity, used to evaluate the product's ability to work under the expected use conditions and performance evaluation during actual storage, transportation and use conditions. It is suitable for aerospace, military, electronics, electrical appliances, petroleum, chemical industry, coatings, plastics, post and telecommunications, medical and pharmaceutical, colleges and universities, scientific research units and other industries to carry out temperature and humidity environmental reliability testing of products.

Structural features:

● Adopt LCD display touch screen controller, the controller operation interface is set with Chinese and English words for selection, the screen operation is simple, the program editing is easy, and it has RS-232 computer interface.
● The large observation window with lighting keeps the box bright, and the built-in glass in the heating body is used to keep the box clearly observed at any time.
● This type of product has the characteristics of high temperature and humidity control accuracy and wide control range. It is equipped with advanced intelligent control devices, man-machine interactive touch screen, color LCD display screen, and can set a variety of programs.
● Unique balanced temperature and humidity adjustment method, electric heating steam humidification, can adjust the ideal temperature and humidity environment. It has stable and balanced heating and humidification capabilities, and can carry out high-precision and highly stable temperature and humidity control.
● A water collecting tray is added between the pipeline of the humidification system and the control circuit board to prevent the leakage of the pipeline from affecting the circuit and improve safety.
● Adopt the compressor imported from France and use all environmentally friendly refrigerants R23, R404, R134.
● The material inside and outside of the box is made of stainless steel plate (SUS # 304), which is formed by CNC digital working machine, the arc is beautiful and elegant, and the flat non-reaction handle is used for easy operation. The exterior and exterior of the cabinet are coated with epoxy resin to increase the appearance and cleanliness.
● The insulation layer of the box is made of high-strength PU foam resin and high-density glass fiber cotton. The thickness of 10 cm can avoid unnecessary energy loss.
● The make-up water tank is placed at the lower part of the front side of the control box. The design of the pull-out water tank is more convenient for the operator to replenish the water source.
● A test hole with a diameter of 50mm is provided on the left side of the cabinet, which can be used for external test power line or signal line.
