A benchtop pH meter is an electronic instrument used to measure the acidity and alkalinity of liquid or semi-solid samples across many industries with applications in waste water, drinking water, food and beverage, chemical and pharmaceutical testing.
Typical benchtop pH meters consist of a measuring electrode, reference electrode, and a meter. The measuring electrode is hydrogen ion [H+] sensitive and measures pH as the sample surrounds the glass bulb at the end. A small voltage output varies with the concentration of the H+ ions in the sample and that is measured and displayed as pH units by the meter. A variety of benchtop pH meters are available with different combinations of measurement modes including pH, mV, ion, and conductivity.
Temperature compensation is an important factor as the pH electrode is temperature dependent. The millivolt (mV) output from the pH electrode will change in correlation to the change in temperature of the sample. This is as a result of a direct change in the H+ ion activity of the sample and ionization of compounds. Depending on the type of pH meter, temperature compensation can be available in a manual or automatic mode.

| Description | pH Meter / pH Tester with GLP data management / high accuracy ± 0.002 pH + 2 digits / data logger / user account with password protection / incl. electrode / rechargeble battery operation
The pH Meter / pH Tester stands for precision, user-friendliness and GLP (Good Laboratory Practice) pH Meter / pH Tester with GLP data management / high accuracy ± 0.002 pH + 2 digits / data logger / user account with password protection / incl. electrode / rechargeble battery operation
The pH Meter / pH Tester stands for precision, user-friendliness and GLP (Good Laboratory Practice) conformity. With a high-resolution LC display, the pH Meter / pH Tester provides a clear and concise display of the measured values. GLP compliance is guaranteed by automatic data recording and traceable documentation. It is possible to measure pH or redox values and temperature with external sensors.
Permanent Measurement Verification (PMV) shows the user where the measured value is within the calibration range using a coloured bar in order to determine whether the measurement is made within the correct range.The electrode is refillable and the diaphragm can be cleaned, which is ideal for very low conductivity or heavy soiling (e. g. paint), which can clog a conventional diaphragm.
The graphically guided calibration makes the process simple and user-friendly. User and sample management allow easy navigation and setting of measurement parameters on the pH meter. Sample information can be saved to facilitate the management and identification of measurements. A generous internal data memory saves extensive records without the need for external storage. The USB-C port on the pH meter ensures fast data transfer and charging. A powerful rechargeable LiPo battery enables hours of measurements before it needs to be recharged.
Overall, this pH Meter / pH Tester represents a significant step in the development of hand-held and laboratory instruments. The high accuracy of ± 0.002 pH + 2 digits, graphically guided calibration, GLP compliance, user and sample management and data storage make it an indispensable tool for scientists, researchers and laboratory technicians who rely on precise pH measurements. It not only improves the accuracy and efficiency of experiments but also facilitates everyday work in industry, quality assurance and the laboratory....
