Model 9200 Analyzer

The Model 9200 Continuous DO analyzer provides the ultimate level of monitoring accuracy and aeration control available anywhere in the world. The analyzer is provided standard with everything available on the Model 9210/9220. It also offers menu directing setup and trend graphing on the display, simultaneous DO and temperature readout on the display, standard automatic sensor membrane self-cleaning, digital AND analog outputs, a sensor output voltage mode, and four programmable setpoint relays. Used with the Model 96A DO sensor, the Model 9200 has become the benchmark analyzer for the DO monitoring & blower control market in the 21st century.
