density meter 1.000-1.040 Warm seawater density meter attached salt water Densitometers
1.000-1.040 length about 27.5 cm
Glass hydrometers use
1 meter floating dry before use must be completely cleaned ,( 59127748, cleaned with soap or alcohol )
2 After the cleaning process after a clean float gauge, hand engraved lines can not take part in the indexing , the index finger and thumb lightly must take in the dry tube top , and be careful not to cross to get , should be perpendicular to take to prevent breakage
3 must be filled with the liquid in the tube clean, so as not to affect the readings
4 To stir the liquid , and so on and then eliminate the floating bubbles gently floating in the liquid meter , the meter on the detection of the floating point , within the next three points of the float, to be good readings into the meniscus , otherwise inaccurate readings
5 To see the floating meter reading method, as marked " meniscus edge reading " float within a small sign outside , the other will be used " under the edge of the meniscus reading ." Figure .
6 When the liquid temperature and standard temperature hydrometers inconsistent readings should be corrected
7 found indexing position paper , glass cracks , surface grime attached and can not be removed when the meter immediately stop using the floats .
