Remove the instrument from the packing material and examine it
carefully to make sure that no damage has occurred during shipping.
If there is any damage, notify your dealer.
Each meter is supplied complete with:
• 4-ring conductivity probe with 1 m (3.3’) cable
• HI 76300 for EC 214
• HI 76303 for EC 215 and EC 215R
• 12 Vdc adapter
• Instruction manual
Note: Save all packing material until you are sure that the instrument
functions correctly. All defective items must be returned in the
original packing with the supplied accessories.
GENERAL DESCRIPTION
EC 214 and EC 215 are bench top multi-range conductivity meters for
the laboratory.
Four measurement ranges ensure the highest resolution and precision for
your measuring requirements.
Single point calibration is performed manually simply by adjusting a
knob on the front of the meter.
Temperature compensation of the readings is automatic for the EC 215
models, thanks to the temperature sensor incorporated in probe, with
userselectable temperature coefficient.
With EC 214 the temperature compensation is manual and the temperature value can be also set with a knob.
The rugged probe with platinum 4-ring sensor responds faster than
conventional stainless steel models and can be also used for measuring
highly acidic or alkaline samples, or at high temperature.
In addition, the EC 215R model offers analog output of 0 to 5V that
represents the full conductivity scale across all 4 ranges.
