pH：
*1 to 5 points calibration with automatic recognition for USA, NIST and DIN buffers.
*Automatic electrode diagnosis shows the pH slope and offset.
*Automatic temperature compensation ensures accurate readings over the entire range.
*Calibration due alarm prompts user to calibrate the meter regularly.
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(For PH-930).
*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.
General Features
