The Hanna HI 2300 measures conductivity, TDS (Total Dissolved Solids), percentage of NaCl and temperature. The auto-ranging feature for EC and TDS measurements automatically sets the resolution suitable to the tested sample thus removing the need to select a range.

If required, the meter can be connected to a computer using the RS232 port and the optional Hanna software will allow data export, plotting, printing.

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 by applying an alternate current to the 4-ring probe which creates a variable voltage directly proportional to conductivity.

A further feature of the meter is the GLP feature which allows users to store and recall data about system status with regards to calibration. After calibration, the meter automatically stores the date and time of the calibration, calibration solution used and the resulting cell constant value. All this information can be recalled at a later date, ideal for ISO9000 laboratories.
