UV Calibration, Certified Water Sensors
Certified UV Calibration Water Sensors for Precise Monitoring and Validation of UV Disinfection and Purification Systems
The Certified UV Calibration Water Sensors are precision photometric devices specifically designed for accurate UV irradiance measurement and performance validation in water disinfection, purification, and treatment systems. These sensors continuously monitor UV intensity inside reactors to ensure proper sterilisation performance, helping maintain compliance with international standards such as DVGW, OVGW, USEPA, and ISO 9001. Each unit undergoes traceable calibration to NIST or PTB standards, ensuring accuracy and long-term stability. Built from high-grade stainless steel with quartz or sapphire optical windows, these sensors resist corrosion and high pressure, making them ideal for industrial, municipal, and laboratory water systems. Available in UVC (200–280 nm), UVB, and UVA configurations, they deliver reliable, real-time feedback for UV lamp output verification and regulatory reporting. Compact, durable, and factory-certified, the sensors form the backbone of safe, compliant, and efficient UV-based water disinfection operations.
Understanding UV Calibration, Certified Water Sensors
Certified UV Calibration Water Sensors are designed for inline and submersible UV intensity measurement within water treatment systems. They ensure the correct UV dose for microbial disinfection by monitoring lamp performance over time. Each sensor contains a UVC-sensitive SiC or GaP photodiode, protected by a quartz or sapphire window for high UV transmission and chemical resistance. These sensors are individually calibrated against certified UV standards (NIST/PTB), guaranteeing consistent, traceable accuracy. Compact, watertight, and temperature-compensated, they deliver precise data under varying flow and pressure conditions. Ideal for compliance-driven applications, they provide essential verification for regulated water purification systems and UV sterilisation units.
