ATI’s Model Q46D Dissolved Oxygen Monitor is designed to provide reliable oxygen measurement and help reduce operating costs. 

Two types of sensing technologies are available for use with the Q46D system: Membraned Electrochemical and Optical (fluorescence). 

Both sensors will provide reliable long-term performance with minimal maintenance. 

No hardware modifications are required to change from one sensor type to the other. 

The monitor can be configured for AC or DC power supplies, and a portable battery-powered unit is available to meet a variety of monitoring needs.
