Mi180 measures 6 different parameters: pH, ORP, EC, TDS (Total Dissolved Solids), percentage of Na CI and temperature in a variety of ranges.
Ph Calibration can be performed in 3 points selectable between 7 memorized 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 or 25°C and the compensation can be also 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 the users to store and recall data on system status. PC compatible through an RS232 port or USB.
