OM-51 Portable Dissolved Oxygen Meter
Overview
This field-type dissolved oxygen meter measures dissolved oxygen concentration (DO), oxygen concentration (O2), saturation (SAT.RATIO) and temperature of water solutions. It uses a laboratory sensor to enable BOD measurement. Waterproof construction enables use at virtually any measurement site. This meter is being used in research institutions, and at a variety water quality related production sites in the mining, agriculture, forestry and fishery industries.
Features
