What should I do if I encounter an emergency during testing in the high and low temperature test chamber?
The treatment of interruption of high and low temperature test chamber is clearly stipulated in GJB 150, which divides the test interruption into three situations, namely, interruption within the tolerance range, interruption under test conditions and interruption under ...Read more -
Eight ways to extend the service life of constant temperature and humidity test chamber
1. The ground around and at the bottom of the machine should be kept clean at all times, because the condenser will absorb fine dust on the heat sink; 2. The internal impurities (objects) of the machine should be removed before operation; the laboratory should be cleaned...Read more -
LCD liquid crystal display temperature and humidity test specifications and test conditions
The basic principle is to seal the liquid crystal in a glass box, and then apply electrodes to cause it to produce hot and cold changes, thereby affecting its light transmittance to achieve a bright and dim effect. Currently, common liquid crystal display devices include Twisted Nematic (TN), Sup...Read more -
