The AdvantEDGE Optical Dissolved Oxygen RDO® Electrode uses the latest technology to measure dissolved oxygen (DO) in demanding environments. The AdvantEDGE Series™ Optical Dissolved Oxygen RDO® sensor o­ffers several advantages for monitoring DO in process applications.

The AquaSelect Multi-Input Process Analyzer is far more than a 4-wire multi-input meter - it is a sophisticated and highly-flexible analysis platform for a wide range of process applications. Because it displays the status of up to four parameters simultaneously, the AquaSelect provides a complete picture of process status on a single instrument. This multi-channel capability reduces both the number of meters required and the time required for installation, maintenance and upgrades.

CLX-Ex2 Residual Oxidant TRO and Chlorine Monitor is a rugged, safe, and low maintenance instrument for shipboard ballast water requiring continuous monitoring and control of residual Total Oxidant levels in hazardous atmospheres. User selectable cycle times, 4-20mA and RS-485 with Modbus output that can be used to control feed pumps and a user selectable alarm allow complete manual or automatic control of chlorine dosing.

The CLX-XT2 Extended Reagent Life Online TRO and Chlorine Monitor is an economical and low-maintenance instrument for shipboard ballast water, potable water, or wastewater applications that require continuous monitoring and control of total chlorine or total residual oxidant (TRO) levels. This marine-grade monitor allows for up to 90 days of unattended operation. The CLX-XT2 offers complete control of dosing & monitoring ballast water discharge through user-selectable sample cycle times, 4-20mA and RS-485 with Modbus output for controlling feed pumps, and user-selectable alarms. The CLX-XT2 is housed in a strong, steel-coated IP56 (except fan IP54) case offering easy access to all service functions and reagents.
