Principle
The instrument detects the hydrogen ion concentration in the sample by triple composite pH Electrode, converts it into a pH value or mV signal, and combines with a temperature sensor for automatic or manual temperature compensation to ensure measurement accuracy. The intelligence system automatically recognizes the standard buffer solution and supports multi-point calibration for accurate calibrating.
Applications
Water quality monitoring, environment testing, laboratory analysis, industrial process control, food and beverage, pharmaceuticals, agriculture, education and research
Steps
1. Boot self-test and select the language
2. Electrode and temperature sensor
3. Measurement mode (pH, mV or temperature)
4. Electrode calibration using standard buffer solution
5. Set the reading mode (automatic, timed, manual)
6. Start measurement and record data
7. Transfer data via USB or Bluetooth
8. Clean Electrode and shut down after use
Notice
• Electrode integrity before use to avoid violent collisions
• Use fresh buffer solution during calibration to prevent contamination
• Electrode cleaning after measurement to prolong service life
• Avoid Operating in Extreme Temperatures or Humidity environments
• Regularly check the battery power to prevent undervoltage from affecting the measurement
Store in a drying place with standard protective cover
• Ensure power stability and prevent interruptions when upgrading firmware
