PRELIMINARY EXAMINATION

EC 214 and EC 215 are digital bench-top multirange conductivity

meters designed for simplicity of use in measuring electrical conduc-

tivity in liquids.

Four ranges of conductivity measurements are provided to cover every

application from deionized water to brine.

The calibration is made simple through the easy-to-operate front

panel knob for slope adjustment.

The conductivity probe does not require re-calibration when switching

from one range to another.

The probe is made of glass with 4 platinum rings that are corrosion

resistant. It is also suitable for measuring conductivity of liquids in

small sample sizes, and comes with a 1 m (3.3') cable.

The temperature effect can be compensated through a knob on the

front panel of EC 214.

With EC 215, the 4-ring probe has a built-in temperature sensor that

automatically compensates for temperature changes in the liquid

tested. The temperature coefficient can be adjusted from 0 to 2.5%

through a knob on the front panel.

It is also available a model with recorder output feature: EC 215R.
