pH and Multi-Parameter Meters
These rugged pH and multi-parameter meters accurately provide the quick water quality measurements essential for electrochemistry research. Choose from compact benchtop or portable pen-styles to fit laboratory or field environments. Efficient dual or multi-parameter technology simultaneously determines different substance levels. The simple user interface shows prompted instructions on high resolution displays. Store the calibrations of potential hydrogen or oxidation reduction with memory storage capability. Incorporating waterproof construction, pH and multi-parameter meters endure harsh environs.
