Benchtop conductivity and temperature meter. Suitable for different types of samples from purified water to brine.
  • It has a backlit LCD display that simultaneously shows the readings of: Conductivity / TDS / Salinity / Resistivity and Temperature, plus date, time, cell status and calibration points.
  • Simple operation through guided on-screen menus with key indicators for the user.
  • Software in Spanish.
  • AUTO-READ function.
  • Stable reading indicator.
  • Selectable cell constant.
  • Selectable reference temperature 15, 20 or 25ºC, with linear or non-linear correction.
  • It includes the standard conductivity/salinity conversion curve.
  • Conductivity/TDS conversion curves, linear or IS/EN27888.
  • Stores up to 1000 readings, associated with date and time, in its non-volatile memory.
  • Easy download of data to PC via USB port or RS232 port with the analysis software.
  • Possibility of incorporating a rod stirrer (code 096019, sold separately).
  • It works with a 220V mains adapter, but can also be powered with batteries (4 alkaline AA type).
  • IP54 splash-proof protection.
