HANNA’ s HI 3222 professional bench meter is designed to provide laboratory results under harsh industrial conditions.

HANNA’ s HI 3222 meter 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 3222 is equipped with 2 input channels for simultaneous measurements. Having these 2 channels eliminates the need for swapping probes and recalibrating.

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 3222 can use ISE electrodes, and provides a choice of measurement units ( ppb, ppm, molarity, weight/ volume % ) . The electrode type and unit 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.
