The industrial and laboratory pH meter is designed for determining the activity level of hydrogen ions. This compact laboratory pH meter determines the pH level and temperature characteristics of the sample, measures electromotive force parameters in various electrode systems, and redox potential values. The pH Meter 3000 meets all requirements for on-site soil pH measurement. The device has a durable dust and moisture-proof casing that is resistant to temperature changes. A new, improved design with a gel-filled immersion electrode and a special membrane sensor allows it to withstand direct measurement loads. The RN 3000 pH meter can be used not only for direct measurements of soil and substrate acidity but also for pH measurements in water solutions and fertilizers. Other advantages of the device include simple calibration using the built-in stability indicator. The device independently recognizes when the calibration process is complete. Additionally, the pH 3000 allows for alternative millivolt measurements to check the performance of pH electrodes (pH/mV), and it is equipped with a low battery charge level indicator (Low-Bat).
