Failure Mechanisms of Cooling Loss in Thermal Shock Test Chambers ——A Systematic Analysis Based on the Reverse Carnot Cycle

Thermal shock test chambers are indispensable in reliability qualification for electronics, aerospace, and automotive industries. Once the “no-cooling” fault occurs, the test sequence is immediately interrupted and secondary damage to the specimen may follow.

Share: Safety tips for the use of test chambers

Safety for any test chamber is very important, now the equipment are set up to protect the measures, in addition to these self-protection warning, in the usual use of equipment in the process also need to pay attention to the following points.

Master These Skills, and Troubleshooting a Constant Temperature and Humidity Test Chamber Is No Longer a Problem

Constant temperature and humidity test chambers may experience malfunctions during use due to improper operation or lack of timely maintenance.
