Product Description The Hanna HI 2550 is a high performance precision instrument that measures a multitude of parameters, each over a wide range. With this single laboratory bench meter you can measure pH, ORP, conductivity, TDS, NaCl percentage and temperature. It comes with the pH electrode, temperature probe and conductivity probe. ISE electrodes, ORP probes and other probes are available at extra cost.

Utilizing an external temperature probe, pH readings are automatically temperature compensated. pH calibrations are customizable - up to 3 reference points, chosen from the 5 available memorized buffers - to ensure a higher level of precision. EC measurements can be compensated relative to a selected reference temperature of 20 or 25°C. The EC calibration mode allows you to chose from among 6 memorized buffers and performed at single-point calibration. The most suitable EC and TDS range for your application is automatically selected.

With a built-in logging function, measurements are stored in non volatile memory, and can be downloaded to a PC through the RS232 serial port. In addition to these features, HI 2550 is contains GLP features that store the calibration and measurement data of any sample, to be displayed upon request.
