Yes it is constant For degree centigrade -0.2 For Fahrenheit - 0.1 And standardised is 20°C and 60.F respectively If it is lower than 20°C then subtract the given temperature and multiply it with 0.2 and if it is higher than 20°C So add the given value and then multiply it with 0.2 For example: if the temperature is 14°C ( less than 20°C) 20-14= 6 6×0.2 = 1.2 If it is 30°C ( more than standardised value which is 20°C ) Then see how much it over then 20°C it's 10 right so multiple 10 with 0.2 10×0.2 = 2

If you don't conduct the test at a specific temperature specified by a reference method, then you must use a temperature factor to make the result more accurate

If you test your sample other temperature than 20 degree Celsius then you will need to use temperature factor. But if you test at 20 degree then no need to use the temperature factor
Thanks for this video. I look forward to a tutorial session on the use of the alcoholometer in subsequent videos. But just a quick question; Does the formula apply to the calculation of alcohol level in spirits using the alcoholometer?
Formula does not vary with the different amount of milk quantity. Formula will be the sample, no matter you used 50ml or 1L milk. Take the amount of milk sample in such a way that the Lactometer float properly into the sample, it could be 50ml, 100ml, 500ml, 1 liter and so on. Always the calculation and formula will be the same, in case of any amount of milk sample.
Rehab Ellehleh, thanks for your comment. Covert the Fahrenheit degree into Celsius. Conversion factor is readily available, just search on Google. After that calculate your test result according to our video.
Received milk temp 30° Milk density - 1.0268 (as per your video calculate) Can you please tell me can I pass milk or not Means in a milk added water or not
Your result is slightly confusing. 1. Pasteurized Milk density should be from 1.028 to 1.032. From your test result, we can say that water is added. 2. But some literature data shown to be found in the range of 1.026 g/cm3 - 1.034 for raw milk. So, you can follow your country's specifications to judge your sample. Thank you.
I think added water cannot be determined by the milk density. To know how much water is added, find the moistute content. Then compare with the reference moisture value of milk to know the amount of added water content.
Explanation about Temperature Factor: According to the FAO guidelines, standard sample temperature of lactometer reading is 20 degree Celsius. But if you take the lactometer reading at any other degree of temperature (e.g. more/less than 20 degree Celsius) instead of 20 degree Celsius, then you have to calculate the density applying the Corrected temperature. In this video, I took the lactometer reading at 27 degree Celsius, thats why I used the corrected temperature.

How do u get 0.2 temperature factor? Is it a constant or? Pls explain
Yes it is constant
For degree centigrade -0.2
For Fahrenheit - 0.1
And standardised is 20°C and 60.F respectively
If it is lower than 20°C then subtract the given temperature and multiply it with 0.2 and if it is higher than 20°C So add the given value and then multiply it with 0.2
For example: if the temperature is 14°C ( less than 20°C)
20-14= 6
6×0.2 = 1.2
If it is 30°C ( more than standardised value which is 20°C )
Then see how much it over then 20°C it's 10 right so multiple 10 with 0.2
10×0.2 = 2
Very clear❤️❤️❤️❤️
I am using a isi 27°c lactometer...will i test the milk in 27°c or 20°c?
Good day please how do u get the temp factor to be 2

The factor 0.2 is fixed or variable

How much Standard Gravity is Necessary for Milk ? Please Tell..
The specific gravity of milk is needed as normally 1.028 - 1,033 kg/litre.
Specific gravity don't have any unit

how to calculate the temp factor please if im doing for instance at 20 degree celcius. thankyou
No factor is needed in case of 20 degree. Factor will be Zero for 20 degree
Thanks nice presentation

Hello, this video was helpful but i have a doubt.. What is the 0.2 temperature factor
If you test your sample other temperature than 20 degree Celsius then you will need to use temperature factor. But if you test at 20 degree then no need to use the temperature factor
@@MicroChemsExperiments so 20 degree means the room temperature , if my room temperature is 32 degree , should i replace 20 with 32

What the reason for adding more than 50 ml milk to measuring cylinder
Milk was added to that amount so that the lactometer scale part float above the measuring cylinder.

Your result is slightly confusing.
1. Pasteurized Milk density should be from 1.028 to 1.032. From your test result, we can say that water is added.
2. But some literature data shown to be found in the range of 1.026 g/cm3 - 1.034 for raw milk.

Below the normal range 1.028,
how to know, how much water added in the milk?
I think added water cannot be determined by the milk density.
