Conductivity meter

The Lutron PCD-431 is an economical yet rugged pocket tester for conductivity and TDS. TDS meter indicates the Total Dissolved Solids (TDS) of a solution, i.e. the concentration of dissolved solids in it.  It is auto-ranging with selectable TDS  or conductivity, and so replaces up to 4 different models from our main competitor. Accuracy is +/-3% of full scale. Because of the adjustable ATC factor, good accuracy is possible over a wide temperature range. Auto power off and rugged IP67 and sensor cover makes this a very handy mobile tool

  • Ranges 0-2,000 µS and 0-20.00 mS auto ranging-Conductivity
  • Ranges 0-2,000 ppm and 0-20,000 ppm-TDS
  • ATC factor adjustable from 0-5%
  • Temperature and ATC to 60ºC resolution 0.1ºC
  • Waterproof to IP67
  • Carbon Rod electrodes for long life
  • Max and Min Hold
  • Dual display – process value / temperature
 TDS meter typically displays the concentration of dissolved solids in parts per million (ppm). For example, a TDS reading of 1 ppm would indicate there is 1 milligram of dissolved solids in each kilogram of water. Conductivity is linked directly to the total dissolved solids

Goes well with the Lutron PH222 pH tester
