Description

The Hanna Instruments-2550 is a two-channel logging micro-processor based meter for measuring pH, ORP, conductivity, total dissolved solids, % sodium chloride and temperature.



With the added benefit of a relative mV feature, this high specification bench meter is perfect for use in professional laboratories.


pH readings are automatically temperature compensated using an external temperature probe. To ensure maximum precision, the meter offers up to five point calibration with seven memorised buffers.


Measurement of mV with a resolution of up to 0.1mV can be taken using ORP electrodes through the pH channel input. It also uses ISE electrodes on the mV scale.


Conductivity measurements can be compensated relative to a selected reference temperature. The EC calibration mode allows the user to choose from among six recognised conductivity standards and perform single-point calibration. The most suitable EC and TDS range is automatically selected. The Hanna Instruments-2550-02 also offers the ability to set and lock the range manually.


GLP capabilities facilitate storage and retrieval of all data for pH, relative mV, EC and NaCl calibration and sample measurement. Data on maintenance and status of the electrode is also recorded.


The built-in logging function allows measurements to be stored and transferred to a PC through a USB interface. Users can manually log up to 200 records and interval log up to 500 records.
