Conductivity Analysers have all of the microprocessor benefits of the pHORP analysers listed above. Along with the two 4–20 mA programmable outputs, full alarm and diagnostic capabilities is an auto–ranging scale from 1 to 200,000 microseimenscm and simple Auto calibration that recognizes your standards. Direct reading % NAOH, % H2SO4, %HCl, % NaCl, TDS, Resistivity, and PID control options are available. The 2–wire versions are reliable, accessible loop powered transmitters.
