Overview
The A120-CN is a professional laboratory pH Meter from the BANTE brand. It is equipped with a 7-inch TFT display, supports 1000 sets of data storage, and the system menu contains 17 optional parameters. Measurement accuracy is 0.002pH. The instrument has pH and ORP dual mode measurement capabilities and is suitable for High Accuracy laboratory environments.
Features
1.7-Inch TFT display, clear and intuitive display
2. Support pH buffer standard (USA/NIST/DIN) or 5 point custom calibrated
3. Electrode diagnostics, display Electrode slope and offset
4. Automatic temperature compensation to ensure accurate measurement of full scale
5. Solution temperature coefficient (STC), compensates for pure water measurement and converts reading to 25 ° C
6. Alarm limit function, automatic warning over range Measured value
7. ORP mode supports 1 point offset calibrated and relative/absolute mV mode
8. calibrate expiration reminder function
9. Automatic end point lock, retain stable Measured value
10. Interval reading mode, supports regular data transmission
11. Password protection to prevent unauthorized operation
12. Extended memory to store 1000 sets of data
13. USB Communication interface
14. One-click reset function
Principle
The instrument detects the concentration of hydrogen ions in the solution by pH Electrode and converts it to pH value display; ORP mode is expressed in mV value by Electrode measurement of Oxidation-reduction potential. Automatic temperature compensation function corrects the effect of temperature on measurement in real time to ensure data accuracy.
Applications
Laboratories, scientific research institutions, water quality monitoring, chemical production, Food processing, pharmaceutical industry, environment monitoring
Standards
USA standard, NIST standard, DIN standard
Steps
1. Connect the power supply and turn it on.
2. Select Measurement mode (pH or ORP)
3. Electrode calibrating (optional 1-5 point calibrating)
4. Set the temperature compensation mode (automatic/manual)
5. Electrode immersion in the solution to be tested
6. Wait for the reading to stabilize and record the data
7. Data storage function to save measurement results
Notice
• Electrode is nondestructive before use
• Regularly calibrate the instrument
• Avoid Electrode Exposure to Air for a Long Time
• Electrode cleaning after measurement
Pay attention to calibrated expiration reminders
• Use the appropriate buffer to calibrate
• Avoid drastic temperature changes affecting Measurement accuracy
• Keep measurement data properly
