Aluminium Alloy Gravity Cup 50ml
(Specific Density Gravity Cup Determiner Pycnometer, Mengukur berat jenis)
Capacity : 50ml
Made of Aluminum Alloy
Designed according to GB6750-86 determination of density of paint and varnish and related products at specified temperatures
Other Equipment Needs :
Thermometer : graduation is 0.1 degree C, accuracy is 0.2 degrees C;
Water bath or constant temperature requirements: if the test accuracy is high, should be kept at the test temperature of the range of 0.5 C, for the production control should be maintained at the test temperature of + 0.2 C;
Analytical balance (or electronic name) : accuracy of 0.2 mg (mg).
How to use :
After cleaning the proportion cup, immediately clean, cool dry or dry (preferably coated with protective oil), placed in the box, room temperature storage.
Volume calculation of specific gravity cup：
Due to the changes of environment temperature, humidity and pressure, the physical and chemical properties of the specific gravity cup of the metal may cause very small changes in the volume of the specific gravity cup. If the measurement accuracy is very high, the volume of the specific gravity cup should be calculated periodically.
The method is as follows: V= (m1-m0) /p
V = volume ml
m1 = specific gravity cup and the quality of water G
G of m0 = empty specific gravity cup
p = water in the density of 23 ° C or other temperature (see table below) g/ml
