Benchtop pH/ORP/lon Meter

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 *Auto-Read function senses and locks the measurement endpoint. *Setup menu allows setting the pH buffer set, number of calibration points, resolution, stability criteria, temperature unit, date and time, etc. *Reset function automatically resumes all settings back to the factory defaults. *Expanded memory stores or recalls up to 500 data sets. *USB communication interface for data transfer and timed interval readings.
