Automatic temperature compensation
As conductivity depends strongly on temperature, each
conductivity value is only valid at the corresponding
temperature. Therefore the device supports temperature
compensation, i.e. referring the conductivity to a reference
temperature (selectable: 20 °C or 25 °C).
Automatic Temperature Compensation
Automatic Temperature Compensation (ATC) in pH mode
(in the range of 0 - 105 °C) when the temperature probe is
connected.
Temperature can be input manually, when the temperature
probe is not attached.
pH Calibration
Automatic Buffer Recognition.
Permissible electrodes’ data: Asymmetry:
± 55 mV / Slope: 45 ... 62 mV/pH
The condition of pH Electrode is checked at each calibration.
1, 2 or 3 point calibration with Lovibond® Standard Buffer, DIN
19266 Buffer or any manually entered Buffer values.
Salinity measurement
Salinity means the sum of amount of all dissolved salts in water.
The unit is g / kg.
TDS measurement (total dissolved solids)
TDS means the mass concentration of dissolved media in a liquid.
The unit is mg/l.
Redox Measurement (ORP)
2 options:
“mV” Standard Redox or mV measurement
"mVH” Conversion to hydrogen systems according to DIN38404 Part 6
rH Measurement
The rH value is calculated from a measured Redox value and
a manually input pH value
