Description

Feature:

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
ORP
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
2 to 5 points calibration, including the 8 concentration points can be selected
Direction 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
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

pH meter pH meter

General Features
Automatic temperature compensation ensures accurate readings over the entire range
