5.2 Calibration procedure
1. Go to the
calibrate menu.
Select the probe, if
applicable. The
display shows the
ORP/Redox
standard solution to
use for calibration.
2. Pour the fresh
standard solution
into a beaker.
3. Rinse the probe
with deionized water.
Dry the probe with a
lint-free cloth.
Rugged probes:
install the shroud.
4. Put the probe in
the standard solution
with the sensor and
reference junction
fully in the solution.
Do not put the probe
on the bottom or
sides of the beaker.
5. Shake the probe
from side to side to
remove air bubbles.
6. Stir gently, then
read the ORP/Redox
value of the standard
solution. The display
shows the mV value
when the reading is
stable.
7. Save the
calibration.
Section 6 Sample measurement
The procedure that follows is applicable to meters that can connect to Intellical ORP (MTC) probes.
Refer to the applicable meter documentation for meter operation and probe-specific settings.
6.1 Sample measurement notes
Read the notes that follow before sample measurements.
• For measurements in reducing-type samples, soak the probe in Reducing Solution for ORP
Electrodes for 3-10 minutes before the initial sample measurement. The soak time significantly
decreases the stabilization time.
• Rinse the probe with deionized water and dry with a lint-free cloth between measurements to
prevent contamination.
• If complete traceability is necessary, enter a sample ID and operator ID before measurement.
Refer to the meter manual for instructions.
• The meter automatically saves the measurement data when the user manually reads each data
point and when the meter is set to read at regular intervals. The user must manually save each
data point when the meter is set to read continuously.
