Ultraviolet (UV) System Sensors

Ultraviolet (UV) sensors are essential components in any UV water purification system. They continuously monitor the intensity of UV light inside the chamber to ensure your water is being properly disinfected. When lamp output starts to drop or mineral buildup on the quartz sleeve reduces light transmission, the UV sensor detects it—allowing the system to alert you before water safety is compromised.

With real-time monitoring, the UV sensor ensures your system maintains peak performance and consistent protection against bacteria, viruses, and cysts. Replacing or recalibrating the sensor at manufacturer-recommended intervals helps ensure reliable operation and supports compliance with U.S. standards such as NSF/ANSI 55 Class A where applicable.

Aquatell offers a selection of genuine replacement UV sensors from trusted brands like Viqua. These sensors are built for accurate compatibility and long-lasting performance, meeting rigorous North American quality and safety expectations. All sensors ship quickly from within North America for fast and dependable delivery.
