PP-15 | pH meter for pH and ORP measurements: High resolution ensures even greater accuracy in electrochemical analysis. The PP-15 Professional Meter can be used for pH and voltage measurements with glass-membrane pH electrodes (combination electrodes) or electrodes with separate reference sensor, and redox electrodes (ORP). Measurement modes: pH, mV, relative mV.
PP-20 | pH and conductivity meter: In addition to pH measurement, the high-end PP-20 Professional Meter offers research-grade conductivity measurements. The results measured are displayed as: conductivity, practical salinity, TDS, NaCl salinity, resistivity. Calibration using up to 5 conductivity standards.
PP-25 | pH and ion-selective meter: In addition to convenient pH measurement, the PP-25 features the added capability of research grade ion-selective analysis for a wide range of concentrations. Calibration with up to 7 calibration points. Concentration readouts in %, ppm, ppt, ppb, mg/l, µg/l and mol/l. Measurements are only possible after calibration. Manual input of the electrode slope possible. The PP-25 supports the following measuring methods for: Direct potentiometry / Standard addition/subtraction / Analate addition/subtraction.
PP-50 | pH meter, ion-selective meter and conductivity meter all in one unit: The fully professional PP-50 combines all features of the above models. This convenient Professional Meter is designed for use in a broad range of applications in the field of potentiometric analysis.
