Simple Design__ Rugged and Less Maintenance
UV4100TDO is a new design instrument to monitor organic pollution in water and the principle is based on UV absorption performance of organics dissolved in water.
The UV4120TDO Organic Analyzer is simple to
operate. Its corrosion-resistant, stainless steel probe features two
windows separated by a 2 mm path length. The UV light projected across the
gap is detected by a photometer. The controller then calculates the light
absorbed by organics in the sample stream. Results are read directly off
the alphanumeric or graphical display.
Method of analysis:
The UV4120TDO Organic Analyzer is based on the
absorption of ultraviolet (UV) light by organic matter. The immersion
probe consists of a dual-beam absorption photometer that provides efficient
compensation for turbidity in the measured medium.
The photometer lays down a measurement beam at the
UV wavelength of 254 nm and a second, reference beam at 550 nm. The
attenuation of the measurement beam is due primarily to the presence of organic
matter, while the attenuation of the reference beam is due primarily to the
presence of suspended solids (turbidity).
The instrument measures spectral absorbance
coefficient (SAC), a physical parameter, and correlates the SAC value to one of
three organic parameters- COD, BOD or TOC. The analyzer can then be configured
to read out directly in one of these parameters in units of mg/L or g/L.
n Direct detector eliminates problems associated with sample pretreatment.
n Self-diagnostic functions continuously monitor analyzer operation.
n Compact and lightweight construction. This simplifies maintenance and allows the use of corrosion resistant reinforced plastic.
n Accurate calibration using stability check function and automatic temperature compensation.
n Simplified span check using built-in optical filter.
n Wide measurement range need not auto-range switching.
n Output can be converted to COD/TOC/BOD/OCA from UV-VIS value.
n Sample extraction style analysis can be performed by attaching a water tank receiver.
The UV spectroscopy measuring principle requires no chemical reagent or calibration solutions resulting in very low operating and maintenance costs.
Simple Design__ Rugged and Less Maintenance
Thanks to simple, large bore tubing,
turbid water with particles in suspension can be monitored without
clogging risks.
An optical turbidity compensation maintains correct measurements.

Automatic cleaning system
A fully automated cleaning system prevents the
measurement flow cell from becoming dirty, giving the analyser autonomy for
several weeks without maintenance.
The cleaning solution (5% sulphuric acid) should be renewed once a month.
This system is more reliable than falling-stream flow cells or in-medium
probes.
Long life Xenon lamp
The xenon lamp has a lifetime of 109 flashes,
equivalent to 10 years of use with one measurement every minute. Or
continue measurement of 1 year.
