Features
The instrument is equipped with different types of pH or ORP sensors. Widely used in power
plants, petrochemical industry, metallurgical electronics, mining, paper industry,
biological fermentation engineering, medicine, food and beverage, environmental
protection water treatment, aquaculture, modern agricultural planting and other
industries. The pH (acidity and alkalinity) value, ORP (redox potential) value and
temperature value of water solution were continuously monitored and controlled.

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 ˫.
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.

Tip: if the user needs to lengthen or shorten the cable, please
remove the black conductive skin outside the transparent wire
to prevent short circuit between the black conductive skin and
the reference end of the electrode.Multimeter can be used to
check, please use special cable for pH connection.
Electrical connection
Connection between instrument and pH or ORP sensors: 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.
