PRODUCT CHARACTERISTICS
The UV-visible differential absorption method has the
advantages of fast response, no sample preparation, no
secondary pollution and easy maintenance compared with the
traditional national standard method.
With spectral correction function, to ensure high measuring
stability of the instrument;
Support SD card storage, storage capacity is large;
With periodic measurement function, real-time storage of
measurement information;
Equipped with RS485 communication interface, interworking
with external terminals;
Set up self-check function, real-time monitoring instrument fault
information state;
The instrument is equipped with concentration alarm function,
which can set the concentration alarm threshold according to
user needs;
The instrument is equipped with turbidity compensation
function to eliminate the interference of turbidity on COD
concentration and improve the accuracy of COD measurement.
The instrument is free from chloride ion interference and is
especially suitable for high salinity scenarios.
PRODUCT INTRODUCTION
LSPEC 7000 Portable water Quality COD analyzer is a differential UV-vis spectrum absorption technology for
the detection of COD and NTU content in municipal sewage, domestic sewage and pollution source outfall. It
adopts UV-visible differential absorption method. Compared with COD measuring instrument commonly used
chemical titration method, it has the advantages of fast measurement speed, high detection accuracy, no
secondary pollution, no interference from chloride ions and no maintenance. It can be widely used in surface water,
river water, waterworks, municipal water supply and drainage, industrial sewage and other fields.
