Multiparameter benchtop pH meter contains 15 options, the meter is suitable for measuring the pH, ORP, ion concentration, conductivity, total dissolved solids (TDS), salinity, resistivity, DO.

pH Mode:

• 1 to 5 points calibration with automatic recognition for USA, NIST and DIN buffers.

• Automatic electrode diagnosis shows the pH slope and offset.

ORP Mode:

• 1 point offset calibration allows adjusting the displayed value to a known standard.

• Relative and absolute millivolt modes ensure the reliable ORP measurements.

Ion Concentration Mode:

• 2 to 5 points calibration, including the 8 concentration points can be selected.

• Direct ion concentration readout simplifies the measurement process.

• Automatic electrode diagnosis shows the calibration points and slopes.

• Selectable concentration units (ppm, mg/L, mol/L, mmol/L) and ionic valency.

Conductivity/TDS/Salinity/Resistivity Modes:

• 1 to 5 points calibration with automatic recognition for conductivity standards.

• Selectable cell constant (K=0.1/1/10), reference temperature (20/25°C), TDS factor, linear

  and pure water compensations, seawater and practical salinity measurement modes.

Dissolved Oxygen Mode:

• 1 or 2 points calibration using the air-saturated water or zero oxygen solution.

• Salinity and barometric pressure compensations eliminate the measurement error.

Other Features:

• Automatic temperature compensation ensures accurate readings over the entire range.

• Auto-Read function senses and locks the measurement endpoint.

• Calibration due alarm prompts user to calibrate the meter regularly.

• Setup menu allows setting the number of calibration points, stability criteria, temperature

  unit, date and time, auto-power off, etc.

• Reset function automatically resumes all settings back to the factory defaults.

• Expanded memory stores or recalls up to 500 data sets.

• USB communication interface for data transfer and timed interval readings.
