>> The Real UVT Online monitor utilizes patent pending Ortho-Beam technology to overcome the inherent problems associated with conventional online UV 254nm instrumentation. This makes it the world’s most technologically advanced, reliable and affordable real time UV 254nm online monitor.

The Real UVT Online monitor’s exclusive Ortho-Beam technology utilizes a multiple path length technique to provide many significant advantages. Ortho-Beam technology is able to provide continuous calibration, allowing for detection and compensation of lamp drift and fluctuations as well as quartz fouling, greatly improving accuracy and reducing maintenance.

The Real UVT Online monitor is the winner of the People's Choice Award as voted by the attendees at the AWWA ACE 07' show in June 2007. This is a testament to the innovation of the Real UVT Online monitor's Ortho-Beam technology

The following illustration provides an inside look at the Real UVT Online monitor’s innovative Ortho-Beam technology.

The Real UVT Online’s exclusive Ortho-Beam technology works by rotating the UV light source and UV sensor around a rectangular quartz flow cell. Two UV 254nm measurements are then taken at 90-degree angles to each other every few seconds, providing two UV 254nm tests through two different path lengths of the test water. The UV 254nm water quality parameter can then be calculated by these two measurements alone, without the need for calibration with a 100% pure DI water reference sample.

The Ortho-Beam technology therefore allows for continuous calibration automatically with every UV 254nm measurement that is made, providing many significant advantages over conventional UV 254nm online testing instrumentation.

Since conventional UV 254nm online monitors have to be calibrated to 100% pure DI water reference water, they become inherently prone to error between the time the system is calibrated, to the time the UV 254nm test is performed. This is due to the fact that the system is susceptible to UV lamp fluctuations and drift over time and fouling of the quartz flow cell. Any of these that occur in the typically long time periods between calibrations in these conventional UV 254nm online systems will cause corresponding changes to the UV 254nm test readings, resulting in inaccuracies and ultimately unreliability of the system.

Since these error-causing components (UV lamp drift and fluctuations and quartz fouling), are the same in each direction through the flow cell, they are intrinsically compensated for with Ortho-Beam technology by the measurement process itself.

The true advantage of greater accuracy and reliability of Real UVT Online monitor’s Ortho-Beam technology in comparison to conventional UV 254nm online monitors can be seen in the following illustration.
