HANNA HI3512 pH/ ORP/ ISE/ EC/ TD/ NaCl/ Res. Benchtop Meter

The HI 3512 is a 2 channel professional benchtop meter with a graphic LCD, designed to provide accurate laboratory results. Channel 1
features pH/ ORP/ ISE and temperature measurement capability while channel 2 measures EC/ TDS/ NaCl/ Resistivity
and temperature.

The pH channel offers up to five point pH calibration with seven standard buffers ( pH 1.68, 4.01, 6.86, 7.01, 9.18, 10.01 and 12.45) and up to
two custom buffers.
