The high and low temperature test chamber can be used to assess and determine the adaptability of electrical, electronic products or materials in the temperature cycle change, product surface storage and use under high temperature or low temperature environmental conditions. It is suitable for high and low temperature reliability tests of industrial products. For the parts and materials of electronic products, ship weapons, universities, scientific research units and other related products, under the circumstances of high and low temperature (alternating) cyclic changes, check their respective Performance indicators. The product has a wide temperature control range, and its performance indicators have reached the national standard high and low temperature test chamber technical conditions, and meet GB / T 2423.1-2008 test A "low temperature test method"; GB / T 2423.2-2008 test B "high temperature test method 》 And other relevant standards, various high and low temperature environmental tests can be conducted.
The high and low temperature test chamber has a perfect shape design, high texture appearance, high quality materials, the surface of the equipment is processed by the matte hairline, processed by CNC machine tools, and adopts a flat non-reaction handle, easy to operate, safe and reliable, beautiful appearance Generous, neat and novel.
The observation window of the high and low temperature test box adopts double-layer glass viewing window, and the “Philips†xenon searchlight inside the box keeps the box bright, and the test article is clearly observed at any time. The conductive film has the advantages of transparency, heat insulation, and not easy to produce steam frost.
The pipeline of the humidification system of the high and low temperature test chamber is separated from the control circuit, and the pipeline of the humidification system is separated from the power supply, the controller, and the circuit board, so as to avoid the influence of the circuit due to water leakage of the pipeline and improve safety.
The air circulation of the high and low temperature test box is driven by the long-axis fan motor to generate wind, and the air is sent to all corners of the box through vertical convection to make the temperature and humidity in the test box uniform and stable. So that the environment of the tested product is balanced, the product test results are very accurate.
Attachment: The wind speed of the high and low temperature box in the test standard is calculated as follows:
V = (VA + VB + …… + VM) / n
In the formula: V——wind speed, m / s;
(VA, VB…, VM) —— wind speed at each measuring point, m / s;
n——the number of measuring points.
