Luminor RS-B2.5 UV Intensity Sensor - 254 nm Teflon Optic, 2.5″ Chamber, Replacement for BLACKCOMB 5.1 and 6.1 LB5/LB6 Series, 4-20 mA Output, Watertight Module

Luminor RS-B2.5 UV Intensity Sensor delivers real-time UV output readings for Luminor BLACKCOMB 5.1 and 6.1 chambers with 2.5-inch reactors. The keyed probe twists into the factory sensor port, plugs into the controller, and immediately shows percentage output on the display, alerting you before performance drifts below recommended values. A Teflon-based 254 nm detector, free-floating cable head, and watertight housing keep measurements stable while preventing cable twist. The built-in 4-20 mA loop and Infinite Expandability Port share data with PLCs, data loggers, or remote alarms. Compatible models include LB5/LB6-021, -031, -061, -101, -151 and other 2.5-inch Luminor systems.

• Real-Time UV Assurance – Continuously measures 254 nm UV intensity and reports the percentage on your BLACKCOMB controller, so you know at a glance that treatment performance is on spec.
• Perfect 2.5″ Fit & Wide Compatibility – Direct-fit for BLACKCOMB 5.1 & 6.1 chambers (LB5/LB6-021, -031, -061, -101, -151) and all NSF Class B 2.5″ Luminor systems—no adapters or re-calibration required.
• Precision Teflon-Based Optics – Teflon lens is self-cleaning while the free-floating, keyed head locks into the optimal angle and prevents cable twist for stable, long-term accuracy.
• 4-20 mA + IEP “Future-Proof” Port – Industry-standard loop output plus integral Infinite Expandability Port let you share UV data with data-loggers, PLCs or remote alarms without extra hardware.
• Watertight, Warranty-Backed Durability – Sealed housing rated for whole-home duty and protected by a one-year, no-hassle manufacturer warranty for worry-free operation.
