2. Sample quality control system<\/p>\n
Q4: Consistency between samples and mass production<\/p>\n
We adopt a triple verification mechanism:
Same production line principle: The prototype and mass production machines share the production line number;
Limit test report: Each prototype comes with 48 hours of continuous working test data;
Parts traceability: The core parts supplier information can be queried through the QR code.<\/p>\n
Measured data comparison:
Heating speed: 92 seconds to 200\u2103 \u00b13 seconds
Noise value: \u226465dB\u00b12dB
Power consumption: 0.85kW\u00b7h\/time\/\u00b10.03kW\u00b7h<\/p>\n
