Water analysis under control: Optimized for perfect handling.

Electrochemical measurements are among the most important analytical processes for evaluating water quality. Parameters such as pH value, the percentage of dissolved oxygen, Redox potential or conductivity of aqueous solutions are the most frequently studied basic chemical and physical parameters. The mobile pH meters, conductivity measuring portable instruments and portable instruments for determining dissolved oxygen in the analysis of drinking water, surface water and industrial process water are suitable for use in agriculture, the food industry and aquarium applications. The advantages are obvious: rugged design, easy handling and minimal error tolerance enable rapid and precise determination of water samples directly on site.

  • G 1000 series: Precision at an outstanding price/ performance ratio
    As an entry-level class, these dust and spray-water-protected precision portable instruments are distinguished by easy operation and low-maintenance sensors.
  • GMH 3000 series: Professional quality for flexible use
    Their durability, top-quality equipment with interface and optionally available data logger function enable professional measurements in the laboratory and in the field.
  • GMH 5000 series: Extremely precise measuring results, even in the harshest conditions
    The durable field measuring devices with a floatable device design deliver precise measuring results even in extreme conditions.
  • G 7500 series: detect several different parameters simultaneously
    The multi-tasking flagship devices analyse various parameters simultaneously in a multi-channel process.

Sensitive measuring technology with durable design.

Sensitive measuring technology with durable design.

With the hand-held devices from the Greisinger brand, the recording of chemical-physical parameters for water analysis is no longer reserved for experienced specialists. With their easy handling and the possibility to connect different sensors to the devices, you have high quality instruments outside on site that also meet upscale standards of a laboratory operation. The only difference is that they have been designed for an environment in which laboratory conditions do not prevail: as field measuring instruments that are completely unimpressed by disturbing factors such as wind and weather during measurement. Because the documentation is at least as important as the measurement, the data loggers can be read out afterwards via common USB interfaces, depending on the device type.

Concentrating on the essentials: the solution.

With a wide range of measuring sensors, we give pH meters and other handheld devices the necessary sensitivity for the respective application. These include universally applicable pH sensors as well as special sensors for the measurement of emulsions, suspensions or for analysis in low-volume sampling. For conductivity measurement of aqueous solutions, a selection of stainless steel, platinum and graphite electrodes is available, covering measurements across the entire range from deionised water to concentrated acid or base. Our calibration service guarantees maximum reproducibility of analysis results through factory calibration to official calibration by our accredited testing laboratories.
