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.
Features
The instrument with different types of pH electrode or ORP electrode is widely used in power plant,
petrochemical industry, metallurgical electronics, mining industry, paper industry
Biological fermentation engineering, medicine, food and beverage, environmental water treatment,
aquaculture, modern agricultural planting and other industries.
In aqueous solution's pH value, ORP value and temperature value were continuously monitored and
controlled.
●Large LCD color LIQUID crystal display
●Intelligent menu operation

Instrument connection
The connection between the instrument and the sensor: the power supply, output signal, relay alarm contact and the
connection between the sensor and the instrument are all inside the instrument, and the wiring is as shown above. The
length of the cable lead fixed by the electrode is usually 5-10 Meters, insert the corresponding label or color wire on the
sensor into the corresponding terminal inside the instrument and tighten it.

Tips: If the user dials the wire by himself, lengthens the cable or shortens
the cable,
Take care to remove the black conductive skin outside the transparent
wire.
To prevent short circuit from the reference end of the electrode, please
use a multimeter to check
Use the pH dedicated cable connection.
