The HI7631233 is a four-ring conductivity/resistivity/TDS/salinity probe to use with the HI6321 benchtop meter.

Recommended for a wide range of industrial process water applications, HI7631233 provides stable measurements over a wide measurement range and does not require frequent calibrations. An integral temperature sensor measures the process temperature and adjusts the measured conductivity to a reference temperature by applying specialized compensation algorithms

The HI7631233 integrated temperature sensor adjusts the measured conductivity to a reference temperature by applying compensation algorithms. The electrolytic conductivity (EC) reading from the HI7631233 sensor can be used to calculate Total Dissolved Solids (TDS), Resistivity, and Salinity (PSU, ppt, or %).

  • TDS is a calculated value based on the conductivity of the solution (TDS = factor × EC25). A TDS factor is a conversion factor used to change an EC measurement to a ppm (or ppt) measurement.
  • Salinity (PSU) relates the ratio of electrical conductivity of a normal seawater sample at 15 °C and 1 atmosphere to a potassium chloride solution (KCl) with a mass of 32.4356 g/Kg water at the same temperature and pressure. Under these conditions, the ratio is equal to 1 and S=35. The practical salinity scale may be applied to values 0 through 42.00 psu at temperatures between 0 to 35 °C.
  • Salinity (ppt) measurements are based on the 0.00 to 80.00 g/L Natural Seawater Scale from 10 to 31 °C. It determines the salinity based upon a conductivity ratio of sample to standard seawater at 15 °C and an approximate salinity value of 35 in seawater.
  • Salinity (%) in this scale 100% salinity is equivalent to roughly 10% solids.
