Principle
The instrument collects signals through the Electrode interface and the temperature interface, and adopts a high input impedance design (≥ 1 × 10 ^ 12 Ω) to ensure the Measurement accuracy. Automatic identification of standard solutions for calibrating, calibrated Linear dispersion through diagrams, use equipotential function to adapt to different Electrodes, and use automatic or manual temperature compensation mechanism for accurate measurement.
Applications
Laboratory, industrial environment, water quality monitoring, chemical analysis, pharmaceutical, food testing, environment monitoring, scientific research and education
Standards
GLP standard, JJG119, METTLER TOLEDO, Merck, DIN19267
Steps
1. Electrode and temperature sensor
2. Power on and select measurement parameters (such as pH, mV, etc.)
3. Automatic or manual identification of standard solutions for calibrating (up to 5 points)
4. Measurement mode (real-time, timing, automatic, etc.)
5. Start measurement, data is automatically stored or manually recorded
6. Print the report or send the data to the computer through the RS232 interface
Notice
• Make sure the Electrode and Temperature interfaces are connected correctly
• Check the standard solution identification status before calibrating
Avoid use in extreme temperature or humidity environments
• Periodic self-diagnostics to check instrument and Electrode performance
• Make sure the computer connection is stable when exporting data
• Use universal power supply (DC9V 500mA, internal positive and external negative)
