Overview
HUAZHI HZP-T503A pH Meter is an analytical instrument for determining the pH value of solutions with High Accuracy and intelligent operation characteristics. It is widely used in universities, environmental protection, food, agriculture, geological prospecting, metallurgy, marine and other fields. It is suitable for acid rain detection and pH measurement of various samples such as surface water, industrial wastewater, drinking water, beverages, daily chemical products, Spinning & weaving products.
Features
1. Fully automatic temperature compensation, support manual temperature compensation.
2. Support 3-point calibrated storage.
3. Electrode slope and usage status are automatically displayed.
4. Built-in 9 groups of buffer, support user-defined 1 group of 9 points.
5. Convenient and simple calibrating, to achieve a key calibrating.
6. The read data is fast and stable.
7. Synchronous display of pH, temperature, and buffer group.
8. The measurement can be read directly in mV or pH.
9. Equipped with a 5-inch color touchscreen, the operation is intuitive.
10. With data statistics function, the measurement results can be counted, consulted, analyzed, compared and saved.
Principle
The pH Meter determines the alkalinity of hydrogen ions by measuring the activity of hydrogen ions in a solution. Since the activity value of hydrogen ions is often small and inconvenient to use, it is expressed by the ph value, which is the negative logarithm of the concentration of hydrogen ions. The instrument senses the activity of hydrogen ions through Electrode and converts it into a readable electrical signal (mV value). After internal calculation and temperature compensation, the corresponding ph value is finally displayed on the screen.
Applications
Universities, environmental protection, food, agriculture, geological prospecting, metallurgy, marine, acid rain testing, surface water, industrial wastewater, drinking water, beverages, daily chemical products, Spinning & weaving products
Steps
1. Press the Mode button to select pH, mV or relative mV measurement methods.
2. Press the calibrate button, the instrument can automatically identify the buffer for calibrating.
3. Using the Settings and Input keys, you can preview Electrode slopes and graphically calibrate Linear dispersion.
4. For measurement, the instrument will quickly and stably read and display pH, temperature and other data.
5. The data statistics function can be used to process and store the measurement results.
