WMB-001 is the core testing equipment for evaluating the combustion chamber sealing performance of gas-fired wall-mounted boilers. It strictly adheres to Clause 7.16 of GB 6932-2015 (National Standard for Household Gas Instantaneous Water Heaters), enabling precise detection of combustion chamber leakage. Equipped with a 1.5% FS precision flowmeter and a PLC + touchscreen intelligent control system, it automates leakage testing and pass/fail judgment for sealed structures. The device is optimized for multiple scenarios, including production line quality inspection, R&D performance validation, and third-party certification testing.
