HI-2300 Conductivity, TDS, NaCl and Temperature Meter information

Hanna's extended description

The HI-2300-02 measures EC, TDS, NaCl and temperature. In conductivity and TDS ranges the instrument automatically chooses the best scale to maintain the highest accuracy.

This instrument utilises a four ring Potentiometric probe with platinum sensors to offer versatility over typical Amperometric designs. By utilising the four ring method, it is possible to measure very low or high conductivity levels without changing probes.

The HI-2300-02 laso provides users with GLP capabilities. Good Laboratory Practice (GLP) is a set of functions that allows storage and retrieval of data regarding the status of the system. After a successful calibration the meter automatically stores the date and time of calibration, the calibration solution used and the resulting cell constant value. All this information can be later recalled by the users.

If required, this meter can be connected to a PC using the optional HI-92000 Hanna Windows Software and HI-920013 USB cable. The software is provided with an exclusive online guide of all the commands available and allows data printing, plotting and exporting.

Key features
