① Use thermometer to measure the
temperature for electrolyte.
② Put the straw of densimeter into
electrolyte uprightly, extrude rubber
tube with hand and the electrolyte will
be sucked into the glasses tube and
then the floater of the densimeter will
float.
③ Numerate the reading of the
densimeter.
CAUTION
The dobber of densimeter must rise
uprightly without depending on the
glass pipe.
2） Measuring the proportion
Use gravimeter to calculate the electrolyte
proportion.
3） Conversion of the specific gravity
The specific gravity at the standard
temperature of 30
0
C should be converted as
follow:
D30= Dt + 0.0007( t - 30 )
Therein to：D30 ——the specific gravity at the
standard temperature of 30
0
C
Dt ——the specific gravity at the
temperature of t0C.
t ——the temperature of the distilled
water during convert.
·The specific gravity referred in this book is
measured all at the temperature of 30℃.
