Operation

i
The ambient temperature must be around
20°C/68°F during the measurement.
i
For a precise measurement to be obtained,
careful calibration is required.
Measuring the urea content:
1. Lift up the light incidence plate.
2. Clean the prism with a clean cloth.
3. Place 2-3 drops of AdBlue on the prism using
the pipette provided.
4. Close the light incidence plate.
 AdBlue spreads across the entire surface
of the prism without air bubbles and dry
patches.
5. Wait 30 seconds.
 The temperature of the AdBlue adapts to
the ambient temperature of the handheld
refractometer.
6. Hold the light incidence plate up to a light
source and look into the eyepiece.
 The urea content is indicated by the light
area on the scale in the eyepiece (item 4,
Fig. 1).
i
The reference value of the urea con-
tent of AdBlue is around 32.5%. The
4
characteristic line (item 1, Fig. 2) on the scale
in the handheld refractometer indicates the
reference value.

i
The permissible deviation of 32.5% urea cont-
ent in AdBlue depends on the manufacturer.
7. Observe the manufacturer's specifications
for the change frequency of AdBlue and urea
content in AdBlue.
!
If the measured urea content deviates from
the manufacturer's specifications, the tested
AdBlue must no longer be used.
