Siemens Combustion AGR450240650 U.V. Tube 322838-752 ensuring zero-gap fitment within theThe Siemens Combustion AGR450240650 U. V. Tube is a high precision replacement phototube engineered for industrial and commercial flame monitoring. Designed as a critical sensing component for Siemens UV Flame Detectors, this tube detects ultraviolet radiation in the 190 to 270 nm spectral range. It is the primary replacement cell for several QRA series detectors, including the QRA2M, QRA10M, and QRA51M models. When integrated into the burner's flame
