Model LXT-330 Universal Transmitter and SP-3X Smart Sensors - pH, Conductivity (Contacting and Toroidal), Resistivity, ORP, Dissolved Oxygen, Specific Ion (pION), Turbidity and Chlorine Dioxide

The Teledyne Analytical Instruments Model LXT-330 Transmitter is a single or dual channel, universal, multi-parameter transmitter designed for the continuous online measurement of pH, conductivity, resistivity, dissolved oxygen, specific ion or turbidity in a general purpose environment.

For hazardous area installations, the Model LXT-380 offers a Class I Div 1 (Zone 1) and Class I Div 2 (Zone 2) approved transmitter with NEMA-4 or NEMA-4X ingress protection. The explosion-proof enclosure is listed with FM and CSA as well as ATEX and IECEx as Ex d. Magnetic switches allow for menu navigation and access to transmitter functions.

The LXT-330 Series transmitters uses the TAI SP-3X series of sensors which cover a wide range of analytical applications. The same transmitter can be used for any measurement, as the SP-3X sensor stores the type and calibration that is automatically retrieved. So a single transmitter can be used for a variety of applications. The communication protocol enables separation distance from transmitter to probe of up to 1000 feet. 4-20mA loop output and MODBUS are standard output options, with optional HART protocol.

The LXT-330 Series transmitters' large, luminescent display features switchable screens including the main numeric screen, graphical screens showing trending charts, and diagnostics. A membrane keypad with soft keys provides an easy-to-navigate interface.
