Measures 4 parameters with 1 single probe. Mi806 offers you a combination of pH, Conductivity, 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.


Mi806 is supplied complete with MA851D/1 pH/EC/TDS/Temp amplified probe with 1 meter cable, 2×20 mL pH 4.01 and pH 7.01 sachets of calibration solution, 2×20 mL 12880 µS/cm sachets of calibration solutions, 2×20 mL sachet of electrode cleaning solutions, rugged carrying case, 9V battery and instructions.
