The OptiView™ measures the UV transmittance (UVT) of drinking water continuously, accurately and in real-time. When paired with a TrojanUV system, the OptiView helps ensure that your water is being treated with the proper dose of UV and gives you confidence that you are maintaining regulatory compliance.
The OptiView is designed specifically for drinking water applications where UVT is between 70 and 100%. The way it measures UVT is unique in the industry and ensures a highly accurate and reliable reading that compensates for lamp and/or sensor sleeve fouling.
By having real-time UVT data, you can avoid overdosing by matching water quality with its required UV dose. When UVT is high, banks of lamps can be turned off or lamp output can be adjusted to extend lamp life and conserve power by up to 25%.
Data from the OptiView can be input directly into a control loop for most UV systems, a SCADA system, or both.
Maintenance can be completed in minutes and without tools. It consists of an annual lamp replacement and sensor calibration as well as a quick clean of the sensor and lamp sleeve every 3 months.
Everyday grab sampling is no longer required, significantly reducing daily workload. OptiView samples water both on a set frequency and automatically if it suspects a change in UVT, ensuring accurate and reliable monitoring.

The OptiView’s small size and wall-mountable design makes it easy to integrate into existing treatment facilities.
UVT is the ratio of light entering the water to that exiting the water. Simply put, water with high UVT allows more UV light to reach the organisms you are trying to treat. As water quality decreases, the UVT is reduced, which in turn reduces the amount of UV light that is able to penetrate and provide treatment.
When a water sample enters the inlet, the motor moves the sensor window so two measurements at different water layers can be taken and compared to determine UVT. This method of measurement ensures an accurate and reliable UVT reading that compensates for lamp and/or sensor sleeve fouling.
