HANNA’ s HI 3221 professional bench meter is designed to provide laboratory results under harsh industrial conditions.

HANNA’ s HI 3221 features up to 5 point calibration with a choice of 5 custom and 7 standard buffers. Users are guided through calibration with graphic prompts on the LCD display. These advanced meters also feature a user selectable “ Outside Calibration� warning as well as a user selectable “ Calibration Time-out� warning.

This meter is provided with a new diagnostic feature to allow users to dramatically improve measurement reliability. Calibration Checkâ„¢ diagnostics system ensures accurate readings every time by alerting users of potential problems during the calibration process. These problems include whether to clean the electrode or check your buffer. After calibration, a probe condition indicater is displayed on the LCD informing the user of overall electrode status.

HI 3221 offers one input channel.

It also offers an extended temperature range from -20 to 120° C ( -4 to 248° F) , using HI 7662-T interchangeable probes and measure ORP with a resolution of 0.1 mV.

HI 3221 can also use ISE electrodes, and displays ISE as ppm. The ion change selection capability and the ISE calibration in up to five calibration standard solutions make this instrument very useful for a large range of concentration solutions measurements.
