CONDUCTIVITY CONTROLLER-TRANSMITTER ALPHA COND 2000
THERMO SCIENTIFIC – USA
General introduction:
Measure from ultra-pure water to highly conductive samples with the Conductivity controller-transmitter Alpha COND 2000 of Eutech – Thermo Scientific: this conductivity controller accepts 4-cell and 2-cell electrodes, and features programmable temperature coefficients to give you precise temperature compensation.
Conductivity controller/transmitter Alpha COND 2000
Features of Conductivity controller-transmitter Alpha COND 2000:
- 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 curves.
- 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.
- Accepts 2- or 3-wire, Pt100 or Pt1000 RTD sensors for automatic temperature compensation.
- Allows user to input cell constant corresponding to connecting electrode independently during calibration.
