Professional Multimeter for pH, EC, TDS & Temperature

The Martini Mi806 is a multi-function portable meter measuring pH, EC, TDS and temperature using a single probe.


  • Measures 4 parameters with 1 single probe.
  • Offers a combination of pH, Conductivity, TDS total dissolved solids and temperature measurements.
  • You can select from a range of calibration buffers and also the temperature scale (°C or °F) can be selected.
  • The multi-parameter probe MA851D/1, includes pH/EC/TDS and temperature, all in one rugged handle.
  • Other features include different TDS factors from 0.45 to 1.00, and a range of temperature coefficients (ß) from 0.0 to 2.4% for greater consistency and reproducibility.
  • The Stability Indicator prompts the user when the reading stabilizes. The Auto-Hold Function automatically freezes reading for later viewing. Large and Easy-to-Read display provides simultaneous readings of pH and Temperature or EC/TDS and temperature
