• Measure from ultra-pure water to highly conductive samples with the Alpha COND 2000 controller/transmitter: this conductivity controller accepts 4-cell and 2-cell electrodes, and features programmable temperature coefficients to give you precise temperature compensation.
• Measures seven ranges, from 0 to 2 µS/cm to 0 to 1000 mS/cm
• Readings of up to three-decimal resolution at ±1 % accuracy
• Adjustable temperature coefficients for more precise temperature compensation: Choose between programmable linear temperature compensation from 0.0 % to 10.0 %, and pure water temperature compensation to correct non-linearity of ultrapure water temperature correction curvess.
• Meter displays electrode status after each calibration
• User-adjustable cell constant values (k = 0.005 to k = 9.999)
• 4-cell electrode prevents polarizing effects and electrode fouling in samples with high conductivity
