4. Definition of Lacto Meter Monday, July 17, 2017 Prepared By MD. MILON HOSSAIN, 5th semester in Shipbuilding Lactometer: AA Lactometer is a little glass instrument that tests the purity of milk based on density/buoyancy.  It is used to find out the amount of water in the milk.  works on the principle of the specific gravity of milk.(Archimedes' principle )

5. Different Figures of Lactometer Monday, July 17, 2017 Prepared By MD. MILON HOSSAIN, 5th semester in Shipbuilding Digital Lactometer

6. How to work Lactometer(Con…) Monday, July 17, 2017 Prepared By MD. MILON HOSSAIN, 5th semester in Shipbuilding # A Lactometer is used to find out the amount of water in the milk that you are drinking. # It works on the principle of specific gravity of milk. # It consists of a TEST-TUBE and a METER BULB. # Using this instrument is very simple.

7. How to work Lactometer (Con..) Monday, July 17, 2017 Prepared By MD. MILON HOSSAIN, 5th semester in Shipbuilding # Put some milk in the test-tube. # Dip the meter bulb in it, the bulb going in first. # You will notice that the meter bulb floats. # The reading on the meter indicates how pure / impure your milk is.

8. How to work Lactometer Monday, July 17, 2017 Prepared By MD. MILON HOSSAIN, 5th semester in Shipbuilding # The deeper the bulb sinks, the more dilute / impure the milk. # If the reading is at the red mark, it shows that the milk is very rich and pure. # With this Lactometer, now you can never be in doubt ! If your expensive Doodhwala says that the milk is pure and you feel otherwise, simply take out your Lactometer and prove him wrong...it will all be crystal clear !

9. calibration The lower the density of the fluid, the deeper the weighted float B will sink; the depth can be read off the scale A The scale is calibrated from top to bottom Monday, July 17, 2017 Prepared By MD. MILON HOSSAIN, 5th semester in Shipbuilding

10. Application of Lactometer Industrial purpose. To avoid the mixing of water in the milk. To check the purity of milk. Monday, July 17, 2017 Prepared By MD. MILON HOSSAIN, 5th semester in Shipbuilding
