Multi-parameter portable pH meter with 8 measurement functions, the instrument is suitable for outdoor measurement of pH, redox potential, ion concentration, conductivity, total dissolved solids (TDS), salinity, resistivity, dissolved oxygen concentration and saturation of liquids.
• Multi-parameter Water Quality Analyzer with large backlit LCD screen.
• 1 to 5 point push-button calibration for automatic recognition of pH standard buffers.
• Optional pH buffer standard (USA/NIST/DIN) or 2-point custom calibration.
• Automatic electrode slope display to prompt the user whether to change the pH electrode.
• 1-point offset calibration that allows adjustment of the display value to a known standard.
• Relative and absolute mV modes provide accurate ORP readings.

Portable pH meter
• 2 to 5 pushbutton calibration, including 8 concentration calibration points.
• Automatic identification of ion-selective electrodes without the need to specify the ion type.
• Direct reading of ion concentration values to avoid tedious conversions and calculations.
• Concentration units (ppm, mg/L, mol/L) are available to meet a variety of ion measurement needs.
• 1 to 5 point key calibration for automatic identification of conductivity standards.
• Selectable cell constant (K=0.1/1/10), TDS conversion factor, normalized temperature (20 or 25°C), linear and pure water temperature compensation,
Seawater and practical salinity measurement mode.

Portable pH meter
• 1 or 2 button calibration, using air saturated water or zero oxygen solution.
• Salinity and atmospheric pressure compensation to improve the measurement accuracy of the instrument.
• Automatic temperature compensation for accurate measurements over the full scale.
• Automatic calibration reminder to remind the user to calibrate the meter regularly.
• Automatic endpoint locking, stable measured values are retained for easy browsing and recording.
• Automatic electrode diagnostics with zero offset, electrode slope, range and conductivity K values.
• The system menu can customize 15 functional parameters such as the number of calibration points, stability standard, data lock mode, automatic shutdown, etc.
• One-key Reset automatically restores the meter to factory default settings.
• Extended memory for up to 500 sets of measurement data.
• Built-in clock automatically marks the date and time of stored data to comply with GLP specifications.
• USB communication interface to send stored data to a personal computer.
• Multi-mode power supply scheme (battery, power adapter, USB port of the computer) to ensure smooth operation of the instrument.
