The YSI 6450AF anti-fouling DO sensor is a luminescent-based DO sensor that provides accurate long-term measurements in severe fouling and low oxygen environments.
This sensor must be installed into a 6-Series sonde to function. Does not function on its own.
Copper-based parts on the YSI 6450AF ROX Dissolved Oxygen Sensor repel aquatic growth on sensors, extending deployment periods.
The 6-Series YSI 6450AF is a luminescent-based dissolved oxygen sensor that offers YSI customers a powerful tool for making long-term oxygen measurements in severe fouling and low oxygen environments. Its rugged design and large measurement range make it ideal for sampling, flow cell, and groundwater measurements.
The optical sensor uses an integrated wiping system to provide anti-fouling in the most hostile environments.
The sensing system is based on the luminescence lifetime method. This method was chosen because it offers the most stable, repeatable and sensitive method for oxygen detection, thus reducing sensor drift and prolonging deployment times.
YSI's optical DO membrane differs from the traditional electrochemical sensor membrane, requiring fewer steps for installation and less maintenance. The membranes will last for one year and are made of a durable material that is unlikely to be damaged in the field. The sensor eliminates stirring dependency that was required of most traditional polarographic sensors.
