pH Meter PCE-PH 228LIQ

pH Meter with GLP data management / high accuracy ±0.002 pH + 2 digits / data logger / user with password protection / incl. electrode / rechargeable battery operation

The pH Meter stands for precision, user-friendliness and GLP conformity (Good Laboratory Practice). With a high-resolution LCD screen, the pH Meter 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.

A permanent measurement verification (PMV) shows the user where the measured value is within the calibration range by means of a coloured bar in order to classify whether the measurement is within the correct range.
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 large internal data memory saves extensive records without the need for external storage. Our pH Meter is equipped with a USB-C port for fast data transfer and charging. A powerful rechargeable LiPo battery enables hours of measurements before it needs to be recharged.

Overall, this pH Meter represents a significant step in the development of handheld 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 does not only improve the accuracy and efficiency of experiments but also facilitates everyday work in industry, quality assurance and the laboratory.
