2.3. Accuracy:
Fat …..……………………………….. …...………………….…... ± 0.06%
SNF ………………………………….. …………...………….…... ± 0.15%
Density ……………………………… ……………………….. ± 0.3 kg/m 3
Proteins ……………………………... ……...……………….…... ± 0.15%
Lactose ……………………………… .…………………………... ± 0.20%
Water content ………………………. .……………………………. ± 3.0%
Temperature of milk ……………….. .……………………………… ± 1 o C
Freezing point……………………….. ..……...………………… ± 0.005 o C
Salts ………………………………... …..…………...…………... ± 0.05%
PH** …………………………………. ………………………………±0.05
Conductivity** ………………………. ……………………..±0.05[mS/cm]
Accuracy values in point 2.3 are in dependence on the correctness of the
corresponding chemical method, used for component content determination.
In point 2.3. are used the following reference methods: Gerber – for fat,
gravimetric – for SNF, Kjeldahl – for protein. The boundary for maximum
variation of repeatability when the power supply voltage is from +10 to – 15%
from the nominal voltage values (220V) have to be no more than 0.8
accuracy according point 2.3. The analyser is used in conditions free of outer
electrical and magnetic fields (except the magnetic field of the Earth) and
vibrations.
2.4 Correct ambient conditions:
Accuracy is guaranteed in case of normal ambient conditions:
Air temperature………………………… ….…from 10 o C to 40 o C (43 o C)
Relative humidity ……………………… ……………...from 30% to 80%
Power supply …………………………
…………………...220V (110V)
extent of contamination at normal environmental conditions…………..2
2.5. Dimensions:………………………….250/290/300 mm, mass 4,0 kg
2.6. Continuous working time:
………….………………………….…...……....non-stop
2.7 Milk sample volume per one measurement:
………………………………..………..15 cm 3 (= 15 ml)
