µDOX: multiparameter handheld instrument for pH, redox potential, dissolved oxygen, total hardness and acid capacity
Description:
µDOX is characterized by its ease of use combined with the measurement quality of high-quality laboratory equipment. It offers accurate, fast and reliable measurements, also in trace level, directly on site – in the field or in production.
The multiparameter handheld measuring device determines relevant water values for the qualitative verification by means of its two sensors. These include pH, redox potential, total hardness, acid capacity and dissolved oxygen. The sensors transmit the measured signals to the handheld measuring unit for an optimal displaying of data. The total unit is particularly easy to handle.
