COMPATIBILITY
Compatible VIQUA Systems
The VIQUA 650580 sensor works with G PLUS, H PLUS, J PLUS, K PLUS, PRO10, PRO20, PRO30, and PRO50 Professional Series UV water disinfection systems. This sensor is designed specifically for higher-capacity commercial and whole-home residential applications where continuous UV monitoring is critical for water safety compliance.
🔧 Declining UV readings don't always mean lamp failure. Clean the quartz sleeve first, then check sensor function before replacing the lamp. A fouled sleeve can reduce sensor accuracy and trigger false low-intensity alarms.
