Pioneers in Dissolved Oxygen
YSI commercialized the first practical dissolved oxygen sensor using the Clark Polarographic electrode in 1962 based on the work of Dr. Leland Clark in conjunction with YSI scientists. This technology became, and still is, the trusted global standard for dissolved oxygen measurement.
Dissolved Oxygen Meter Selection
A DO meter measures the amount of oxygen dissolved in an aqueous solution. There are two primary types of dissolved oxygen sensing technologies available: the optical based sensing method which is commonly referred to as luminescent and the Clark electrochemical or membrane-covered electrode. The two types of electrochemical sensors available are polarographic and galvanic.
