HI-4221 Research Grade Bench pH & ORP Meter information

Hanna's extended description

The customised user interface can display two channels at once - showing the measurements in various modes: basic measurement with or without GLP information, graph or log history.

pH can be calibrated automatically up to 5 points with 8 memorised values (pH 1.68, 3.00, 4.01, 6.86, 7.01, 9.18, 10.01, 12.45) + 5 custom buffers.


Order Information


The HI-4221-02 is supplied with glass body pH electrode, temperature probe, power adaptor, pH 4 and pH 7 buffer solutions, electrode refilling solution, electrode holder and instructions.
