Measurement With Ion-Selective Electrodes (Ise/Ion) - XS Instruments Revio Manual De Instrucciones

Measurement with ion-selective electrodes (ISE/ION)

This series of devices can measure the concentration of ions such as ammonium, fluorides, chlorides,
nitrates etc., using an ion selective electrode specific for the ion of interest. Connect the electrode to the
BNC connector in green measuring channel. Connect any reference electrode to the Ref connector next to
the grey channel for Conductivity.
• Setup for ISE Parameter
• In measure mode, press the button
Using the directional keys, move to the "ISE" menu

• Move with directional keys
The table below shows the setup menu structure for ISE parameter; for each program there are the options
that the user can choose and the default value:

Measuring unit
Access this menu to select the measure unit with which to calibrate the instrument and read the sample:
• mg/l -default-
g/l
•
• mol/l
Note: use the same unit of measure for the calibration and measurement.
IMPORTANT: If the unit of measure is modified, the calibration is automatically cancelled
Select low standard
Access this menu to select the concentration of the first point of the calibration curve (more diluted
standard). The other point will automatically be identified by the software, by multiplying the concentration
by a factor of 10.
Example: Low standard 0.050 mg/l, the other calibration points expected by the instrument will be
0.5 / 5 / 50 / 500 mg/l.
The device can accept from a minimum of 2 to a maximum of 5 calibration points, once the second
calibration is finished, the user can stop the calibration by pressing
up to that moment.
Set Stability criteria
Access this menu to choose which stability criterion to use for calibration and measurement.
• Stability: Equivalent to the "Medium" stability criterion for pH.
