Portable pH / Ion Meter

FEATURES:

pH:

  • 1 – 5 points calibration with automatic recognition for USA, NIST and DIN buffers
  • Automatic electrode diagnosis indicates pH slope and offset

ORP:

  • 1 point offset calibration allows adjustment of displayed value to a known standard
  • Relative and absolute millivolt modes ensure reliable ORP measurements

Ion Concentration:

  • 2 – 5 point calibration, including the 8 concentration points, can be selected
  • Direct ion concentration readout simplifies the measurement process
  • Automatic electrode diagnosis shows calibration points and slopes
  • Selectable concentration units (ppm, mg/L, mol/L, mmol/L) and ionic valency

GENERAL FEATURES

  • Automatic temperature compensation ensures accurate readings
  • Auto-read function senses and locks the measurement endpoint
  • Calibration reminder
  • Auto-power off conserves battery life
  • Setup menu allows setting the number of calibration points, resolution, stability criteria, temperature unit, date and time etc
  • Reset function available to default instrument to factory settings
  • Expanded memory up to 500 readings
  • USB communication interface to transfer data
