Hydrometer large scale div 0.01g / cm3

Hydrometer large scale div 0.01g / cm3

Hydrometer larger scale, for a first assessment of the density value so you can choose the right tool at an accurate determination
Of universal type for lighter liquid and heavier than water
Scale 0, 700 to 2.000 g / cm³, division 0.01 g / cm³, reference temperature 20 ° C with ballast lead, length about 360 mm, without thermometer.

Measuring procedure:
- Place the liquid to be controlled in a transparent cylinder current of appropriate size;
- Lower the temperature to the value indicated by reference hydrometer;
- Before the measure agitate the liquid with a glass rod to eliminate areas with different density and temperature;
- The d clean ensimetro should only be touched above the scale;
- Make sure that the liquid does not adhere to the above 5 mm from the point of reading, as this could alter the outcome;
- Also the meniscus should be stable and not c hange its shape or height when the stem moves up and down;
- When the hydrometer has reached equilibrium, gal Leggia freely without touching the walls of the cylinder;
- The density of the word is read "from below" in the case of transparent liquids, for non-transparent liquids the word is read "from above." Check the temperature of the liquid immediately after the reading. The maximum permissible temperature for measurements with hydrometers without thermometer is 70 ° C.
