The 2402B conductivity meter is suitable for water, waste water or pure water conditioning in continuous or batch-type operating modes, for liquid chromato-graphy or for general chemical process monitoring. 

The accuracy is better than 0.5% at 2.25%/°C between 15°C and 120°C.

Temperature coefficient of the cell is compensated either manually or automatically by an external Pt-100 platinum resistor probe within the range of 0°C to 120°C. The slope can be adjusted between 1.5%/°C and 3.0%/°C. Commercially available conductivity cells - K-factor 0.01, 0.1 and 1.0 cover a dynamic range from 0.01µS to 20mS full scale. An internal synchronous rectifier eliminates the capacitive error currents induced by the cell cable.

The measuring signal is transferred to the output as a signal current of either 0...20mA or 4....20mA. Two floating limit or alarm contacts can be set over the entire range. Each can be defined as a normally open or as a normally closed contact. 

Supply lines and all other lines, either from or to the conductivity meter, are protected by internal noise limiters against HF- noise
