What should I do if the high and low temperature test chamber is struggling to open?

The high and low temperature test chamber is laborious to open

Answer: The trouble of opening the door of the high and low temperature test chamber mostly occurs in summer or rainy season. This is because there are irregular small holes on the contact surface between the door and the door cover. Moist air enters the small holes and forms condensation. When the door is closed, the condensed water drains the air in the hole and creates a negative pressure. In addition, the magnetic force of the door seal and contamination of the relay can cause mixing. Attractive, so when you open the door of the high and low temperature test chamber, it feels very hard. The elimination method is to regularly clean the door seal of the high and low temperature test box with soapy water to maintain good elasticity and smoothness, eliminate condensation, and apply a little talcum powder to eliminate it.
