Dissolved oxygen sensors are used to measure the amount of oxygen dissolved in a unit volume of water. In water quality applications, such as aquaculture (including fish farming) and wastewater treatment, the amount of dissolved oxygen (DO) must be kept high. Search by Specification | Learn More

Surface tension and wettability instruments measure fluid surface tension, a tangential force that keeps a fluid together at the air/fluid interface. Surface tension is a direct indicator of the quality of any chemical and any formulation. Search by Specification | Learn More
