• Immerse the probe tip 4 cm (1
1/2
”) into the sample.
• Press
pH

• Stir briefly and wait a few minutes for the measurement to stabilize.
Measured pH value is displayed on the screen.

• If measurements are taken in different samples successively, rinse
the probe thoroughly to minimize cross-contamination. After rinsing
with water, rinse the probe with some of the sample to be measured
next.
7.2. EC / TDS
• Immerse the probe tip 4 cm (1 ½”) into the sample.
If possible, use plastic beakers to minimize any EMC interferences.
• Tap the probe lightly on the bottom of the beaker to remove any air
bubbles trapped inside.
• Press the
μS/cm
or
ppm
key to select EC or TDS measurement mode.
or
• Wait a few minutes. Displayed measured value (in μS/cm or ppm)
is temperature compensated automatically.
