LXT-220-N Nitrate Analyzer

The LXT-220-N utilizes Teledyne's nitrate and chloride ion electrodes with functionality of the proven LXT-220 electronics to provide an reliable nitrate reading in wastewater treatment and environmental applications.

The direct nitrates are detected with a nitrate pION electrode as well as a pH electrode as an additional measurement. A chloride ion electrode is also included as it is a common interferent to the nitrate reading for compensation. All three rebuildable electrodes are housed in a single probe for ease of installation with signals being fed back to the electronics. The LXT-220-N software performs the calculations to provide a nitrates reading.

The LXT-220 controller is weatherproof NEMA-4X DIN form factor with universal mounting bracket available for panel, wall, handrail or pipe mounting. The membrane keypad and backlit LCD display provides an easy-to-use interface with menu-driven functionality. 4-20mA output is provided as standard and configurable alarm contacts can be provided optionally. Information is digitally communicated between sensor and control units which ensures EMI/RFI robustness and enables separation distances up to 200 meters.
