HI 4522 is our high-end multiparameter research-grade bench meter, measuring pH/ORP/ISE/EC/Temperature and more. It comes equipped with a backlit 240 x 320 dot-matrix color screen with on-screen help, simultaneous graphing, language selection and custom configurations. pH can be calibrated automatically up to 5 points with 8 memorized values (pH 1.68, 3.00, 4.01, 6.86, 7.01, 9.18, 10.01, 12.45) + 5 custom buffers.
For conductivity this meter features EC, resistivity, TDS and salinity measuring scales and stages 1, 2 and 3 USP modes plus linear and natural water temperature compensation. 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.
ISE features include:
Direct calibration with measurements in multiple units.
Incremental methods include:
• Known addition
• Known subtraction
• Analyte addition
• Analyte subtraction
