Home Paramters Salinity SX650 conductivity / resistance / TDS / salinity meter

SX650 conductivity / resistance / TDS / salinity meter



The Apera Instruments SX650 is an ideal instrument for measuring conductance in all areas, such as Hydroponic culture, drinking water, etc. The conductivity electrode is interchangeable and very narrow for measurements in small vessels, e.g. Test tubes.

  • At the same time EC / Resistance / TDS /Salinity are tested quickly, accurately and reliably
  • ± 1.0% F.S accuracy; Automatic 1-pointcalibration; Automatic temperature compensation 0-50 ° C
  • A slim, replaceable electrode suitable for test tubes
  • Intelligent functions: switching from ˚F to ˚C,automatic switch off
  • Complete set: 1413μS / cm standard solution andCR2032 battery in case
  • CE-Certified with a 2 year warranty for the meter and 6-months for the probe.
