Moreover, they offer an extended temperature range from –20 to 120 ºC

(–4 to 248 ºF), using HI 7662-T interchangeable temperature probes.

These instruments can also measure with ORP electrodes, thanks to their

capability to measure mV with a resolution up to 0.1 mV.

HI 3221 and HI 3222 can also measure with ISE electrodes on ppm scale. The

electrode type and unit selection capability (for HI 3222), the ion change

selection capability (for HI 3221) and the ISE calibration in up to five

calibration standard solutions make this instrument very useful for a large

range of concentration solutions measurements.

Other features include:

• Relative mV measurements

• Log on demand up to 400 samples

• Log interval with log on stability feature up to 600 records

• Auto Hold feature, to freeze first stable reading on the LCD

• GLP feature, to view last calibration data for pH, Rel mV or ISE

• PC interface
