Equipped with professional ultraviolet induction chip, the probe only captures ultraviolet spectrum generated by gas and methanol flame, effectively isolating interference from workshop LED lamps, incandescent lights and ambient natural light to prevent false flameout alarms.\u003c\/div\u003e\n\u003cdiv\u003eQRA2 is standard short probe for small and medium compact gas burners; QRA2M extended long probe fits deep cavity combustion heads and large industrial gas kilns. After successful ignition, the detector continuously transmits stable UV flame signal to the program controller to maintain normal fuel supply. If accidental flame loss happens during running, the UV photocell instantly cuts off signal output and triggers safety interlock to close gas valve, eliminating risks of fuel leakage and deflagration.\u003c\/div\u003e\n\u003cdiv\u003eUnified external fixing thread, integrated signal wire and plug terminal fully match original installation structure. Users can directly replace aging, carbon-fouled and low-sensitivity old UV probes without modifying burner internal wiring and mounting brackets. High temperature resistant quartz lens blocks oil mist and carbon deposit, guaranteeing long-term stable detection performance under high temperature boiler environment.\u003c\/div\u003e\n\u003c\/div\u003e\u003c\/div\u003e\u003cdiv style='font-family:ui-sans-serif, system-ui, sans-serif, \"Apple Color Emoji\", \"Segoe UI Emoji\", \"Segoe UI Symbol\",
