• Displays conductivity, resistivity, ppm and temperature units • Measured process & temperature can be displayed together • Compliant with current USP requirements • Full ultra pure water temperature compensation • Ultra pure water to solution concentration measurement • Auto range, remote range or single range operation The contacting conductivity input allows connection with LTH contacting conductivity cells with a cell constant of K= 0.01,0.1, 1.0 and 10. It is also possible to use other manufacturer’s conductivity cells with a cell constant between K= 0.01 and 10. This offers a wide operating...

Range & Sensor Compatibility Tables CONDUCTIVITY RANGE Note 1: The maximum measurement range will be limited by the solution temperature. With the temperature compensation slope set to 2%/°C, this will derate linearly from full scale at 25°C to 50% of scale at 100°C.

• Displays conductivity, % solution concentration, salinity and temperature units • Able to simultaneously display conductivity, % solution concentration, salinity and °C • Ideal for cooling tower bleed, rinse water and solution concentration applications • Preset curves stored for common chemicals and salinity • 2 independent custom curves offering up to 9 points can be entered • Adjustable temperature compensation slope Covering a wide range of conductivity measurement, from water (200 pS/cm) to solution concentration measurements (1,000 mS/cm), it is possible to display the readings in conductivity...
