UviTec
The UniTec UV254 M3000 is a continuous UV 254nm
UV254 Analyzer M3000
organic testing monitor which utilizes ABB's Ortho-
Beam technology, shown in the following
illustration.
The UniTec UV254 M3000's innovative Ortho-Beam
technology is designed to take sensor readings at
90-degree angles to each other through two
different path lengths through a rectangular quartz
flow cell. The two sensor readings give the amount
of light able to pass through two different path
lengths of test water. From these two
measurements alone, the UV transmittance (UVT) or
UV absorbance (UVA) of the test water is calculated
without continuous need for calibration with
DI water.
Measurement made easy
