| | Research Grade Laboratory Bench Meters
Five point calibration with standard and custom buffers
Auto recognition of probe type (2 or 4 ring, and nominal cell constant)
Extended range from 0.001 µS/cm to 1 S/cm
HANNA’s new family of research grade laboratory benchtop instruments feature a 240 x 320 dot-matrix color display with on-screen help, simultaneous graphing, language selection and custom configuration. Four models are available to measure pH, pH and ISE, conductivity, pH and conductivity. HANNA’s pH meters feature a 5 point calibration with a choice of custom or memorized buffers and provide the user with the exclusive CAL CHECK™ electrode diagnostic system. ISE models allow direct calibration and measurement with a choice of units, as well as incremental methods. Our new conductivity meters have EC, resistivity, TDS and salinity measuring scales. EC has an extended range from 0.001 µS/cm to 1 S/cm with auto recognition of the probe type used. Salinity measurements can be displayed in practical salinity, natural sea water or in percent scale. All conductivity models feature stages 1, 2 and 3 USP modes plus linear and natural water temperature compensation. All models are equipped with USB and RS 232 ports for PC connectivity and offer logging, graphing and GLP.
HI 4221 are supplied with glass body pH electrode, temperature probe, power adapter, pH 4 and pH 7 buffer solutions, electrode refilling solution, electrode holder and instructions.
