Oxygen saturation or dissolved oxygen (D.O.) is a relative measure of the amount of oxygen that is dissolved or carried in a given medium.
The easiest and most accurate way of measuring oxygen is to use an oxygen meter, and most oxygen meters, especially dissolved oxygen meters, have membrane covered polarographic sensors that generate an electrical current when they measure oxygen.
Dissolved oxygen meters are used in a wide variety of industries, from aquaculture to wastewater, to determine the concentration of oxygen in aqueous solutions in the field or in the laboratory. The oxygen level is often critical, and therefore needs to be monitored with reliable equipment.
AirPro is committed to selecting the best products for our customer’s needs, it is this commitment that led us to OxyGuard. For almost two decades AirPro have worked with OxyGuard to supply water quality measuring and monitoring equipment for our customers. Due to reliability, low maintenance demands and ease of maintenance, OxyGuard instruments have an excellent total cost of ownership.
Recent developments in design allow not only measurements, but also control over oxygen usage. Such systems as the OxyGuard Commander allow users to set D.O. limits to optimise the use of the oxygen automatically. Other critical parameters can also be logged to a local PC, the operator can access this information remotely, via phone lines, the internet or radio link.
