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
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,
1. Apparent damage to the analyzer
2. The analyzer does not work properly or provides specied 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 specications, and instructions are included in
the operation manual. Comply with the technical specications 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.

Measurement Setup
Electrode Setup
When the pH electrode connected to this instrument, you need to select the electrode type as “PH” in this item. It’s the same when the
electrode becomes OPR.
Temperature Setup
There are four kinds of temperature types: NTC2.252K , NTC10K , PT100 and PT1000, user needs to choose the right temp comp for the
electrode to display the right temperature. “Err” means no temp comp.
The user can compare the temperature measured by other standard instruments with the temperature measured by the D300. If there is
an error, you can use the “temperature offset” to modify it, assuming that the temperature measured by D300 is 25°C, and the temperature
measured by other standard instruments is 24.8°C. Then enter “-0.2°C” here, then press “Esc”, and then select “Save”.
You can choose Auto, Manual and None in `Temperature input`. Choosing `Auto` the temperature is from electrode. Choosing “Manual”,
user is able to input the temperature. Choosing “None” there will be no display of temperature, the default temperature of the system is
25°C as comp.
User can choose (°C) and (°F)
