Principle
The instrument detects the concentration of hydrogen ions in the solution by triple composite pH Electrode, converts the signal into pH value display; adopts intelligent end point determination technology, combined with temperature compensation and calibration functions to ensure measurement accuracy and Stability.
Applications
Water quality monitoring, environment testing, laboratory analysis, industrial process control, education and research
Standards
Instrument level 0.01, pH Measurement range -2.00~ 18.00pH, pH resolution 0.01pH, pH Electronic Unit Indication Error +/- 0.01pH, mV Measurement range -1999~ 1999mV, mV resolution 1mV, mV Electronic Unit Indication Error +/- 0.1% FS
Steps
1. Turn on the self-test to confirm the status of the instrument
2. Select equilibrate measurement or continuous Measurement mode as needed
Electrode calibration of pH (1-3 points) with automatic identification or custom buffer solution
4. Electrode is immersed in the solution to be tested, and the pH value is read after intelligently determining the end point
5. Data is automatically stored to support subsequent access and management
6. Clean Electrode after use, shut down or automatically shut down
Notice
• Electrode integrity before use to avoid violent collisions
• Standard buffer solution is used during calibration to ensure accuracy
• Pay attention to temperature compensation settings during measurement to avoid environment interference
• Charge regularly, pay attention to the battery undervoltage reminder
• Keep the instrument drying to meet IP65 protection requirements
• Follow the instructions when upgrading the firmware to prevent data loss
