Mi170 Autoranging Conductivity / TDS / NaCl / Temperature Laboratory Bench Meter

Mi170 measures 4 different parameters - EC, TDS (Total Dissolved Solids), percentage of NaCl and temperature in a variety of ranges.

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 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.
PC compatible through an RS232 or USB port.

Mi170
More accurate readings with the 4-RING MA814DB/1 EC / TDS / NaCl and Temperature probe.
Conductivity readings are performed by applying an alternate current to the 4-ring probe which creates a variable voltage depending on the conductivity.
Rear Connector Panel layout
Communication to the PC is done via opto isolated USB and RS232 ports.
