WDet-7000 Integration Water Quality Online Analyzer

Overview Of WDet-7000 Integration Online Multi Parameter Water Quality Analyzer
WDet-7000 multi parameter water quality analyzer is a high-level integration of
a multi-parameter water quality analyzer. Our multi parameter water analyzer
uses a modular design, each parameter using independent sample and analysis
module, to realize the use of any combination such as COD, ammonia nitrogen,
total phosphorus, total nitrogen and a variety of heavy metals. The applied
reagent can be configured according to relevant national standards. ZETIAN
multi parameter water quality analyzer can be widely used in water pollution
monitoring, industrial process water, industrial and municipal wastewater
treatment, and surface water monitoring, etc. Besides series of water quality
testing instruments in ZETIAN, there are also types of air quality monitors for

Features Of WDet-7000 Integration Water Quality Online Analyzer

High accuracy and reliability, strong capability of anti-interference
● Global initiative magnetic conductivity measurement technology thoroughly
solves the problem of chromaticity, suspended solids, and bubbles
● The multi parameter water quality analyzer's special design of flow and
reagent ratio, high precision, low detection limit (COD:10mg/L, ammonia
nitrogen: 0.01 mg/L)
● ZETIAN multi parameter water quality analyzer has constant optical fiber and
light intensity compensation algorithm, small drift for long-term operation
● Imported single channel high integration valve terminal technology which is
easy to maintain, dismantle and clean

Modular design, more convenient combination
● A single HMI module can connect with multiple analysis modules, to
facilitate the measurement combination of multiple parameters
● Each module has independent sample, resolution and measurement function, no
cross interference
● The multi parameter water quality analyzer's structure design has high
compatibility, the monitoring module can be replaced according to the field

A variety of practical function, providing user-friendly operation
● When a reagent leaks, instruments will automatically alarm and prompt the
user for maintenance
● Automatic processing of abnormal state: when power exception occurs during
the operation, the instrument will diagnose abnormal state and clean flow path
back to wait for sample status after power is back.
● Exceed standard sample retained function: samples of abnormal data will be
retained for manual analysis
● Simple operation: touchscreen control panel and friendly software interface,
providing abundant information; the software is simple to understand
● A digital lock screen, prevent others from the wrong operation
● The water quality analyzer supports to install the mini thermal printer,
which can be used to print the test data. with a built-in Bluetooth module,
GPRS wireless transmission module, it can realize the remote software upgrade
