WTW FDO® 925-3 optical IDS sensor

FDO® 925 – the Optical Dissolved Oxygen Sensor for Field and Lab •Robust and waterproof •Extremely fast (t99 < 60s) •Free of incident flow with beveled membrane •Factory calibrated sensor cap with intelligent chip •Low maintenance The FDO® 925’s small dimensions make it suitable for lab and process. The flow-free, easy-to-clean, beveled membrane allows it to be used in containers with low sample volumes. Low oxygen concentrations under 1 mg/l can also be detected accurately. The fast and flow-free FDO® 925 is perfectly suited for field measurement. Accessories such as protective armor made of plastic or stainless steel, make this sensor ideal for use in harsh environments. The Kevlar®- strengthened cables of varying lengths allow reliable measurements in deep lakes or raging rivers. In the sewage plant, FDO® 925 excels at BOD measurement in the Karlsruhe bottle as well as in the monitoring of stationary measurement systems. In connection with the AutoRead function of the MultiLine® devices, its characteristics can be aligned to that of the online sensor FDO® 700 IQ and thus guarantees comparable measured values.
