In the field of inorganic analysis, the corresponding measurement technology is also used in schools and universities, which is particularly suitable for training students. An outstanding example of this is the digital multi-parameter hand-held measuring instruments of the HORIBA WQ 300 series, which have been specially developed for checking water quality.
These devices make it possible to regularly check the water quality and to react quickly to potential problems, such as gastrointestinal diseases caused by contaminated water. Thanks to their ease of use, teachers, caretakers or hygiene officers can carry out the measurements independently. With precise results in real time, the hand-held measuring devices not only support safety and health in educational institutions, but also offer practical learning experiences for students.
By integrating the devices into science lessons, students learn to measure environmental parameters such as pH, conductivity or oxygen content and to understand their significance for the environment and health. At the same time, scientific skills, critical thinking and an awareness of environmental protection and sustainability are promoted.
The HORIBA WQ 300 series impresses with its user-friendliness, precision and versatility in the classroom. With these devices, students can learn how to apply the digital technology of the future in a practical way and recognize interdisciplinary connections in subjects such as biology, chemistry and geography.

This high-precision pH meter delivers measurements with a resolution of 0.01 pH. Equipped with a replaceable electrode, temperature sensor and open measuring chambers, it is particularly versatile. The large, three-colour LCD display shows not only the measured values, but also the calibration buffers used and the stability of the measurement. Calibration is conveniently performed at the touch of a button. In addition, you can read the mV value for diagnosing the pH electrode. Other practical functions include temperature measurement, automatic temperature compensation (0–60 °C), automatic switch-off and self-diagnostic messages in the event of low battery power or calibration errors. The device is ideal for laboratory, industrial or mobile use. IP protection class: IP67 With replaceable probeManufacturer item number: 50014053
