pH meter 5000

The modern way of pH-measurement

pH 5000 meets all requirements for the application of soil- and/or water pH measurements in an outstanding way. It is particularly designed for direct pH measurements in soils and other growing media. The rugged field-ready housing is well-protected against dust, moisture and air humidity.

The gel-filled insertion probe is developed especially for soil analyses. Therefore it can measure pH both directly in soil and in liquids.

pH 5000 is provided with automatic calibration. According to 2-point-calibration, clean and dry electrode should be inserted into the pH 7 solution first. The pH meter recognizes each buffer solution automatically. After the value on the display is stabilized, the electrode should be dried up and inserted into the pH 4 solution. The integrated stability indicator signalizes termination of the calibration procedure. Even a 3-point calibration with additional buffer pH 10 could be carried out if necessary.

“Low-Bat” indication during the measurement signalizes a low state of the battery.

pH measurement directly in soils, substrates and solutions, e.g. irrigation water.

  • Easy-to-use: The automatic buffer recognition during calibration also ensures a high level of operating convenience and additional safety.
  • Always ready to go: The unit is delivered in a sturdy aluminium case, with all accessories stored safely and within reach.
  • Multilingual: Easy to understand menu is available in three languages: German, English and Russian.
  • Smart: Evaluation via the COMBI 5000 app provides quick and easy storage and interpretation of all measured values for different plants.
