GENERAL DESCRIPTIONGENERAL DESCRIPTION
GENERAL DESCRIPTION
GENERAL DESCRIPTIONGENERAL DESCRIPTION
EC 214 and EC 215 are digital bench-top multirange conductivity
meters designed for simplicity of use in measuring electrical conductivity 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.
