The equipment meets the relevant requirements of Q/DR 0532.02-2007 standard; Specially developed for performance testing of liquid expansion temperature controllers for 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;

The wiring terminals of the thermostat are firmly in contact with the contacts on the test bench, and then the probe is inserted into the water through the sink hole to immerse the probe. The thermostat is adjusted to the highest temperature control point. Do not heat the water until the thermostat is activated. Observe the difference between the water temperature reading and the thermostat reading, as well as the difference between the water temperature reading when

 turned on and off. The heating and cooling speed should not exceed 1K/min. The test results should comply with the temperature error of the thermostat's turn off temperature, which is ± 5 ° C, and the on-off difference, which is ± 3 ° C. Repeatability: Repeat the temperature characteristics test 10 times; The system records the effective continuous power on time and displays the on/off indicator light. The device has the advantages of strong universality, simple operation, 

convenient control, and low failure rate.
