1. The equipment meets the relevant requirements of Q/DR 0532.05-2007 standard;

2. This non-standard testing equipment should be designed according to the requirements of temperature controller testing, specifically developed for manual temperature controller testing of water heaters. The machine adopts PLC processor+computer+display, and relevant data can be set, displayed and saved in the interface. The main accessories of the machine are imported and well-known domestic brands, effectively ensuring the overall performance and reliability of the equipment;

3. Temperature characteristics: Immerse the temperature sensing part of the manual reset temperature controller in the medium of the temperature test tank. The manual temperature controller is initially in the on state. When the temperature of the medium in the temperature test tank rises to the point where the contact opens, record the temperature value of the disconnection. The temperature controller cuts off the temperature range (97-110 ℃). When the temperature in the sensing part drops below 40 ° C, it should be able to manually reset and turn on. Repeat the test four times in a row.
