Hanna pH/ORP/ISE Graphic LCD pH Benchtop Meter - HI3221-02

HI3221-02 pH/ORP/ISE Graphic LCD pH Benchtop Meter by Hanna Instruments

HANNA’s HI 3221 benchtop instrument features up to five point pH calibration with a choice of five custom buffers and seven standard buffers.

HI 3221 features an interactive user support interface that assists you before, during and after measurement. On-screen tutorials guide users through set-up, calibration and measurement while context sensitive help of any screen is available at a push of a button. The help screen includes language specific assistance for menu parameters, calibration, logging, contact and accessory information for your instrument.

This instrument features HANNA’s exclusive Calibration Check™, a diagnostics system that ensures accurate pH readings every time. By alerting users of potential problems during the calibration process, the Calibration Check™ system eliminates erroneous readings due to dirty or faulty pH electrodes or contaminated pH buffer solutions during calibration. Throughout the calibration process, users are guided step-by-step by the on-screen tutorial. After calibration, the probe condition is evaluated and an indicator is displayed informing the user of the overall pH electrode status.

The HI 3221 is equipped with one input channel.

This instrument can measure using ORP electrodes (pH channel input), thanks to it's capability to measure mV with a resolution up to 0.1 mV. The HI 3221 can use ISE electrodes in the ppm scale (pH channel input) and provides a choice of measurement units (ppb, ppm, molarity, weight/volume %).
