Analyzers and Transmitters 
Analyzers, transmitters and wireless devices for continuous process monitoring of pH, ORP, contacting conductivity, toroidal conductivity, dissolved oxygen, gaseous oxygen, chlorine, ozone, and turbidity.
Model 1056 Intelligent Four-Wire Analyzer
The Model 1056 dual-input analyzer offers single or dual sensor input with an unrestricted choice of dual measurements thus reducing the cost per loop and saving panel space.
Model 1057 Multi-Parameter Analyzer
The Model 1057 three-input analyzer offers single or dual sensor input with an unrestricted choice of dual measurements thus reducing the cost per loop and saving panel space.
Model 1066 Two-Wire Liquid Analytical Transmitter
The Model 1066 loop-powered transmitter measures pH, ORP, conductivity, resistivity, oxygen, free chlorine, total chlorine, monochloramine and ozone serving a wide range of liquid analytical applications
Model 5081 Two-Wire Transmitter: pH/ORP, Conductivity, Oxygen, Ozone or Chlorine
The Model 5081 family of transmitters can be used to measure pH, ORP, conductivity (using either contacting or toroidal sensors), resistivity, oxygen (ppm and ppb level), free chlorine, total chlorine, and ozone in a variety of process liquids.
Model 56 Advanced Dual Input Analyzer
The Model 56 Analyzer offers single or dual sensor input with an unrestricted choice of dual measurement combinations. The high resolution full-color display gives unsurpassed visibility and functionality for liquid analytical instrumentation.
Model 6081 Wireless Transmitter for pH and ORP and Conductivity
The Models 6081-C and 6081-P wireless transmitters are ideal for monitoring applications, especially in hard-to-reach or cost prohibitive locations. Model 6081-P measures pH and ORP. Model 6081-C measures conductivity.
Model Xmt Two-Wire Transmitter
The Model Xmt family of transmitters is used to measure pH, ORP, conductivity, resistivity, oxygen, free chlorine, total chlorine, monochloramine and ozone in a variety of process liquids.
