Features
Industrial online conductivity meter is a microprocessor-based water quality online
monitoring control instrument.The meter is equipped with conductivity electrodes with
different constants This instrument is widely used in power plants, petrochemical industry,
mining industry, paper industry,semiconductor industry , medicine, food and beverage
and other industries.It is suitable for softening water, raw water, steam condensate water,
seawater distillation and deionized water, etc. It can continuously monitor and control
the conductivity, resistivity, TDS, salinity and temperature of aqueous solutions.

Preface
Thank you for your support. Please read this manual carefully before use.The correct use
will maximize the performance and advantages of the product, and bring you a good
experience.
When receiving the instrument, please open the package carefully, check whether the
instrument and accessories are damaged by transportation and whether the accessories
are complete. If any abnormalities are found, please contact our after-sales service
department or regional customer service center, and keep the package for return
processing.
This instrument is an analytical measurement and control instrument with highly
precision.Only skilled,trained or authorized person should carry out installation, setup and
operation of the instrument.Ensure that the power cable is physically separated from the
power supply when connection or repair.Once the safety problem occurs, make sure that
the power to the instrument is off and disconnected.
For example, it may insecurity when the following situations occur:
1) Apparent damage to the analyzer
2) The analyzer does not work properly or provides specified measurements.
3)The analyzer has been stored for a long time in an environment where the temperature
exceeds 70 °C.
The analyzer must be installed by professionals in accordance with relevant local
specifications, and instructions are included in the operation manual.
Comply with the technical specifications and input requirements of the analyzer.

Electrical connection
Connection between instrument and sensor: Connection of power supply, output signal, relay
contacts and instrument baseplate. The cable length of sensors is usually 5-10 meters. There are
labeled inserts at the end of the cable, which can be inserted into the terminal with the same
digital symbols on the instrument roof and tightened.
