DESCRPTION

•  pH
  Multi-point (1…5) calibration for more linearity.
  Selectable resolution from 0.001 pH to 0.1 pH.
  Automatic calibration with any of eleven pre-programmed and five user specified pH buffers. Create your own buffer/temperature tables!
  Accepts pH electrodes with any zero point (Eo) between ±999 mV.
• mV
  Features mV calibration for accurate ORP measurements.
  Selectable resolution from 0.1 mV to 1 mV.
• Ion
  Direct concentration measurement.
  Multi-point (2…5) calibration and an additional blank correction for measuring low concentrations.
• Conductivity
  Multi-point (1…3) calibration for more linearity.
  An electrode with a typical cell constant of 1 cm-1 (standard) permits to measure from 0.01 µS/cm to 200 mS/cm in five ranges.
  An electrode with a typical cell constant of 0.1 cm-1 permits to measure from 0.001 µS/cm to 20 mS/cm in five ranges.
  An electrode with a typical cell constant of 10 cm-1 permits to measure from 0.1 µS/cm to 2000 mS/cm in five ranges.
  Automatically selects correct range and frequency.
  Selectable reference temperature: 20° or 25°C.
  Automatic calibration with any of three preprogrammed and three user specified standard solutions. Create your own standard/temperature
  tables!
  Allows to lock the initial conductivity range to avoid non-linear titration curves.
  Accurate low conductivity measurements by eliminating the capacitive component of the electrode and its cable (avoid the use of long cables!).
• Dissolved oxygen
  Operates with a galvanic dissolved oxygen electrode requiring no polarisation time and no zero calibration.
  Selectable resolution from 0.01 mg/l (0.1%) to 0.1 mg/l (1%).
  Automatic air pressure compensation 600-1300 hPa.
•  Temperature
  Reads temperatures with 0.1°C resolution.
  Manual or automatic temperature compensation (O2: 0…50°C).
  Calibrates temperature probe for quality measurements
