Operating instructions of YGDW high and low temperature alternating damp heat test box

High and low temperature alternating heat and humidity test chamber

【Overview】

Features

The temperature controller of the high and low temperature alternating heat and humidity test chamber adopts the TH7110 series wide-screen panel LCD programmable temperature controller, which can be operated at a fixed value or a program, and the operation is simple and convenient. The refrigeration unit adopts French Taikang unit. The test box is equipped with a vacuum observation window with electrothermal coating, which can effectively solve the problem of condensation in the observation window. The test box adopts the overall integrated assembly structure, and the appearance is beautiful and elegant.

Main purpose and scope of application

The high and low temperature alternating humidity and heat test chamber is mainly used to test the temperature and humidity stress of the test piece, and can be used in aerospace, aviation, electronics, metallurgy, petroleum, chemical industry and other industries.

3. 【Structure characteristics and working principle】

The box body of this high and low temperature alternating humidity and heat test box adopts an integral structure. The inner plate is 1.0mm thick SUS304 stainless steel plate, the outer plate is 1.2mm thick cold-rolled steel plate, the surface is electrostatically powder coated, and the middle is filled with 100mm thick rock wool as an insulation layer.

The upper part of the test chamber is the working room, the right side is the electrical appliance control room; the lower part is the refrigeration unit, the lower right rear door is equipped with a water storage bucket for humidification, and a conductive film heating glass window is installed in the middle of the door to ensure that it can work under low temperature and high humidity Effectively observe the state of the test piece.

The control system of this high and low temperature alternating humidity and heat test chamber adopts Visuo TH7110 series wide-screen panel LCD display programmable temperature controller, PLC programmable controller and non-contact solid state relay, which can programmatically control the temperature and humidity of the test chamber, and Real-time paperless recording and storage of temperature and humidity test curves can be performed. (Up to 100 days)

The high and low temperature alternating heat and humidity test chamber has multiple safety protection functions:

Over-temperature protection function;

Water shortage protection function;

Compressor overload protector

Compressor overpressure protection.
