pH Mode:
• High accuracy benchtop multiparameter water quality meter is equipped with a large backlit
  LCD display.
• 1 to 5 points push-button calibration with auto-buffer recognition.
• Selectable pH buffer standards (USA/NIST/DIN) or using the custom calibration solutions.
• Automatic electrode slope display helps user decide whether to replace sensor.

ORP Mode:
• Single point offset calibration allows adjusting the displayed value to a known standard.
• Relative and absolute millivolt measurement modes provide accurate ORP readings.



Ion Mode:
• 2 to 5 points calibration including the eight concentration calibration points can be selected.
• Automatically recognize ion selective electrodes, does not need to specify type of ion.
• Direct ion concentration readout simplifies the elaborate measurement process.
• Selectable multiple concentration units including the ppm, mg/L and mol/L.

Conductivity/TDS/Salinity/Resistivity Mode:
• 1 to 5 points push-button calibration with automatic calibration solution recognition.
• Selectable cell constants (0.1/1/10), normalization temperatures (20/25°C), TDS conversion
  factors, seawater and practical salinity measurement modes.

Dissolved Oxygen Mode:
• 1 or 2 points calibration using air-saturated water and zero oxygen solution.
• Manual salinity and barometric pressure compensation improve the measurement accuracy. 



Other Features:
• Automatic Temperature Compensation provides accurate reading over the entire range.
• Calibration Due Reminder prompts user to calibrate the meter regularly.
