HI 2212

pH Benchtop Meter with Three Point Calibration

The HI 2212 is a pH and temperature benchtop meter.

Calibration can be performed at up to three-points using five standard and two custom buffers.

This instrument features manual or automatic temperature compensation with the HI 7662 temperature probe.

GLP (Good Laboratory Practice) feature provides data consistency. A calibration reminder can be set to alert the user, that too much time has elapsed since the last pH calibration and a new one should be performed.
