pH - mV - Ion - Conductivity - Resistivity - Salinity - TDS - Dissolved oxygen - Air pressure - Temperature

pH

• Mulit-point (1...5) calibration for more linearity.

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 0.001µS/cm to 20 mS/cm in five ranges.
• An electrode with a typical cell constant of 10 cm-1 permits to measure from 0.1µS/cm to 2000 mS/cm in five ranges.
• Automaticly selects correct range and frequency.
• Selectable reference temperature: 20°C or 25°C     
• Automatic calibration with any of three preprogrammed and three user specified standard solutions.
  Create your own buffer/temperature tables!
• Allows to lock the initial conductivity range to avoid non-linear titration curves.
• Accurate low conductivity measurements by eliminating the capacitve component of the electrode and its cable (avoid the use of long cables!).

Dissolved oxygen
