Characteristics:

Multiparameter meter contains 15 optional parameters pH, ORP, Ion, conductivity, TDS, salinity, resistivity and DO of the samples.

pH Mode:

• 1 to 5 points push-button calibration with auto-buffer recognition.

• Automatic electrode slope display helps user decide whether to replace the pH electrode.

ORP Mode:

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

• Relative and absolute millivolt measurements provide accurate ORP readings.

Ion Mode:

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

• Selectable multiple concentration units including the ppm, mg/L and mol/L.

Conductivity/TDS/Salinity/Resistivity Mode:

• 1 to 5 points push-button calibration, automatically recognizes the standard solutions.

• Selectable cell constant, normalization temperature, TDS conversion factor, seawater and

practical salinity measurement modes.

Dissolved Oxygen Mode:

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

• Manual salinity and barometric pressure compensations ensure accurate measureme
