Combined Conductivity / pH Meters
Milwaukee Mi180 pH/ORP/EC/TDS/NaCl/Temperature Laboratory Bench Meter
The Milwaukee Mi180 measures 6 different parameters: pH, ORP, EC, TDS (Total Dissolved Solids), % of NaCl and Temperature in a variety of ranges. pH calibration can be performed in 3 points selectable between 7 memorised buffers, to provide a very accurate calibration curve even when testing different samples, where very wide differences in pH can be found.
The auto-ranging feature for EC and TDS measurements automatically sets the resolution suitable to the tested sample. All measurements can be temperature compensated at 20°C or 25°C and the compensation coefficient is selectable by the user.
The automatic temperature compensation can also be disabled for measuring the actual conductivity value. The stability indicator on the LCD ensures accuracy. Conductivity readings are performed with the 4-ring probe supplied with the meter. The GLP feature allows users to store and recall data on system status. The Mi180 is PC compatible through an RS232 port or USB.

A wide-ranging laboratory analysis instrument performing measurements of pH, ORP, Conductivity, TDS, NaCl and Temperature. All measurements are automatically compensated for changes of temperature, but can be disabled for 'actual' conductivity readings. Conductivity, TDS and NaCl readings are all performed with a single probe with no need to interchange for different ranges. The pH and conductivity circuits have been electrically separated so that there is no interference between them.
Supplied complete with pH electrode, temperature probe, EC/TDS/NaCl probe, electrode stand x1, buffer solutions, electrolyte refill solution, mains power supply and instruction manual.
