pH
• Multiparameter water quality meter is equipped with a 6.5 inches backlit LCD display• 1 to 5 points calibration with automatic recognition for USA, NIST and DIN buffers• Automatic electrode diagnosis shows the pH slope and offset
Conductivity/TDS/Salinity/Resistivity
• 1 to 5 points calibration with automatic recognition for conductivity standards• Selectable cell constant, reference temperature, TDS factor, linear and pure water compensations, seawater and practical salinity measurement modes
• Automatic electrode diagnosis shows the calibration points and factors
Dissolved Oxygen
• 1 or 2 points calibration using the air-saturated water or zero oxygen solution• Salinity and barometric pressure compensations eliminate the measurement error
