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.

Utilising an external temperature probe, pH readings are automatically temperature compensated. pH calibrations are customisable – 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 USB port. In addition to these features, the HI 2550 contains GLP features that store the calibration and measurement data of any sample, to be displayed upon request.

HI 2550 is supplied with HI 1131B pH electrode, HI 76310 conductivity probe, HI 7662 temperature probe, HI 76404 electrode holder, pH 4 and pH 7 buffer solutions, HI 7071S electrolyte solution, 12 Vdc power adapter and instructions.
