At Top Instruments you will find a dissolved oxygen meter for water. There is available a dissolved oxygen meter for both pure oxygen content and for oxygen concentration. The dissolved oxygenmeter has a water resistant design, interface and internal data memory as well as the classical version for laboratories. The dissolved oxygen meter is usually a hand device due to the fact that it is the most demanding chemical instrument for water analysis with a high accuracy and ease of use. Calibration of the dissolved oxygen meter for water is very easy to perform (manual two-points calibration or automatic calibration), therefore even inexperienced customers can calibrate the instrument.
