2 Overview
Thank you for purchasing from Chemtrac, Inc.
The UVM5000 is a continuous UV 254nm organic testing monitor
which utilizes an innovative dual path measurement technique,
shown in the following illustration.
The UVM5000 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.
By continuously taking readings in the two directions through
the flow cell, calibration is effectively performed every time a
sample is taken. Therefore, quartz fouling and lamp fluctuations
are inherently compensated for by the measurement process
itself, improving accuracy.
