(1) The high-quality high-low temperature test chamber has a firm paint layer with uniform surface color, no scratches and peeling. Each plated piece is bright and bright.
(2) The inferior machine is mainly caused by the detachment of the paint layer. Spare parts such as: sample holders, hooks, rubber soft plugs, etc. are characteristics of inferior test chambers. Start the high and low temperature test chamber, run at low temperature for about 30 minutes, open the door to observe whether the evaporator is frosted, and touch the water with your hand to touch the inner wall for sticky feeling. If frost is found, there is also a sticky feeling, and the machine has good cooling performance.
(3) Stop the high and low temperature test chambers, open each three times, each time for three minutes, the high quality machine should start normal, no automatic shutdown phenomenon.
(4) The door seal of high-quality high and low temperature test chambers should be tight and there is no air leakage phenomenon, while the inferior high and low temperature test chambers tend to have loose door seals, which makes the insulation performance worse.
(5) The high-quality high-low temperature test chamber has no obvious vibration during operation. After working for about 20 minutes, the condenser should be hotter at the upper part and warmer at the lower part. If the upper part is very hot and the lower part is not hot, it indicates residual air inside the system. Too much to increase power consumption.
