Features SD 300 pH

Min / Max Value Memory highest and lowest measured value is saved.
Auto Hold freeze and display measurement.
Auto Power Off if unused, the meter automatically switches off after a selected period (0 to 120 min, or deactivated)
Additional Display for pH Electrode and Battery Bar graph display
Low Battery Display “BAT” 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: ±55mV/Slope:45…62mV/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.
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

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).

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.
