Preface
Please read this manual carefully before use.
When receiving the instrument, please open the package carefully, check whether the instrument and accessories are damaged by trans-
portation 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,
1. Apparent damage to the analyzer
2. The analyzer does not work properly or provides specied 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 licensed professionals in accordance with relevant local specications, and instructions are included in
the operation manual. Comply with the technical specications and input requirements of the controller.
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.
Large color LCD display
Intelligent menu operation
Multiple automatic calibration
Double high resistance measurement mode, stable and reliable
Manual and automatic temperature compensation
Three relay control switches
High & low alarm and hysteresis control
4-20mA (2-wire), 4-20mA (4-wire direct to controller), or 4-20mA + RS485
Multi parameter display simultaneously shows – pH, Temp, mV, etc.
