PCE High-precision pH meter PCE-PH 228

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

Permanent Measurement Verification (PMV) shows the operator where the measured value is in the calibration range using a coloured bar to indicate whether the measurement is in 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 stored to facilitate the management and identification of measurements. A generous internal data memory stores extensive records without the need for external storage. The USB-C port on the pH meter ensures fast data transfer and charging. A powerful LiPo battery enables hours of measurements before it needs to be recharged.

All in all, this high-precision 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 not only improves the accuracy and efficiency of experiments, but also makes everyday work in industry, quality assurance and the laboratory easier.
