3PCs Alcoholmeter Wine Alcohol Meter Concentration Meter Vodka Whiskey Alcohol Instrument Wine Hydrometer Tester Wooden Box

The alcohol concentration measured by a breathalyzer is only at standard temperatures

(20%) is the actual concentration of alcohol. However, in the actual work, the temperature of alcohol can not be the standard temperature 20C, so it is necessary to convert the alcohol concentration measured at the non-standard temperature to the alcohol concentration at the standard temperature, which is the actual concentration of alcohol.

2, the temperature application range of this table: 0~+40°C

 

Third, use method

1, the need to measure the alcohol first poured into the measuring cylinder (three groups of 100 ml can be used) alcohol can not have dirt or turbidity phenomenon.

2, wipe the thermometer upright in the measuring cylinder (about 1 minute) to read the temperature value, and then wipe the 40-70 alcohol meter slowly sink into the measuring cylinder, then there will be three situations:

① The liquid level is within the scale range, so that the reading can be prepared.

② The liquid level is below the scale range, and the low alcohol meter needs to be replaced.

③ The liquid level is higher than the scale or the bottom of the alcohol meter, and the height alcohol meter needs to be replaced.

3, reading when the liquid level in the scale range can be read after the static stability, the reading position is the liquid level and the scale level (according to the lower edge reading), write down the alcohol meter reading.

4, look up the table conversion table at the top of each page of the alcohol meter to measure the number of degrees, find the corresponding degree, the leftmost column of the conversion table is the temperature, find the corresponding temperature, the two values cross, that is, the actual degree of alcohol.

Allowable error of glass float meter

1, all kinds of glass float meter allowed error except second class standard oil density

The SY-05 type petroleum densitometer is 0.6 minimum index value of soil, and the rest are 1 minimum index value of soil.

2, all kinds of floating meters with thermometers, the temperature error is

S 1 minimum division.

Instructions for use

1, the float meter must be cleaned before use, not

Rub it directly with your fingers.

2. Do not hold it with your hand below the highest degree line, so as not to

It affects the reading.

3. When the liquid temperature does not conform to the standard temperature of the float meter, note

The readings taken should be corrected,

4, the reading must pay attention to read the float meter and the liquid level is good

Contact the liquid bend, otherwise the reading is inaccurate, must be re-

Re-reading after cleaning the diameter of the pipe: When making a precise measurement, it should be determined in the same way several times and take its average value.

5, when reading, except for special provisions, read the liquid level

Where the horizontal line meets the diameter of the float gauge.

6. The float meter should be kept properly and not placed in a position susceptible to vibration

And where there are sudden changes in temperature.

7, if the position of the indexing paper is found to move, the glass tube is cracked

Marks, contusions, and surface contamination that cannot be removed
