The Model 4520 is a fully specified Conductivity/Resistivity/TDS/Salinity/Temperature meter that includes full support for good laboratory practices (GLP). The meter supports one, two or three point conductivity calibration. Powerful data logging capabilities are included with the ability to store up to 500 readings either manually, at timed intervals or alarmed events. Remote monitoring and data collection is facilitated by the provision of both analogue and digital outputs and in the event of power removal all user defined parameters are retained. A newly launched DataWay PC software program is useful for data acquisition. Data can be automatically or manually logged and displayed in both tabular and graphical form. Special features for Good Laboratory Practice (GLP)
