The high-precision portable pH ion meter contains 3 measurement functions. The meter is suitable for measuring the pH, oxidation-reduction potential and ion concentration of the sample. The measurement accuracy is 0.002pH.
Features of pH mode:
• High-precision portable pH ion meter with backlit LCD display.
• 1 to 5 point calibration, automatic identification of USA/NIST/DIN standard buffers.
• Automatic electrode diagnosis, display pH slope and zero offset.
ORP mode features:
• 1-point offset calibration, allowing adjustment of the displayed value to a known standard.
• Relative and absolute mV modes to ensure reliable redox potential measurement.
Features of ion concentration mode:
• 2 to 5 point calibration, including 8 concentration calibration points for selection.
• Directly read the ion concentration value to avoid tedious conversion and calculation.
• Automatic electrode diagnosis, with calibration point and slope display.
• Optional concentration units (ppm, mg/L, mol/L) and ion media.
• Automatic temperature compensation to ensure accurate measurement of the full range.
• Automatic end point lock, keep stable readings for easy browsing and recording.
• Calibration due reminder, reminding the user to calibrate the meter regularly.
• Automatic power off, effectively saving battery power consumption.
• The setting menu can customize the number of calibration points, display resolution, stability conditions, temperature units, date and time, etc.
• Reset function, automatically restore the meter to the factory default settings.
• Expand memory, store or recall up to 500 sets of data.
• USB communication interface, easy to transfer data to a personal computer.
• Multi-mode power supply scheme (battery, power adapter, computer USB port) to ensure the smooth application of the meter.
