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
