Thermo Scientific Alpha COND 2000

Conductivity Controller/Transmitter:

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

Conductivity:

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
