Pioneers in Dissolved Oxygen
We Know DO
Dissolved oxygen (DO) is a critical parameter for many applications, such as aquaculture, environmental monitoring, and wastewater treatment. YSI commercialized the first practical dissolved oxygen sensor in 1963 based on the work of Dr. Leland Clark in conjunction with YSI scientists. The technology became, and still is, the trusted global standard for dissolved oxygen measurement.
Dissolved Oxygen Meter Selection
DO meters measure the amount of oxygen dissolved in an aqueous solution. YSI offers two primary types of DO sensing technologies: optical-based sensors and the Clark electrochemical or membrane-covered electrode. Optical dissolved oxygen (ODO) sensors don't require a warmup time or stirring for accurate readings. ODO sensors are available for the ProSolo, ProSwap, and ProDSS. Electrochemical sensors (galvanic and polarographic) require more maintenance but offer faster response times and lower acquisition costs. Both galvanic and polarographic sensors are available for the Pro20, Pro20i, Pro1020, and Pro2030.
