Product Description
Product name: | Soil hydrometer |
Measurement range： | 0-60 -5-50 0.955-1.30 |
Uses: | A soil hydrometer B soil hydrometer |
Densitometer test steps include:
1. The soil sample with moisture content should be used for the particle analysis test by the density meter method. It can also be carried out by air-drying (drying) soil samples;
2. For air-dried (dried) soil samples, take 100-300 g of representative soil samples, put them in a mortar, and grind them with a pestle with a rubber tip. Pass the ground soil through a 2mm sieve, grind and sieve the soil on the sieve until only particles larger than 2mm remain on the sieve;
3. The soil samples with a particle size of less than 2 mm were mixed uniformly, and the soil samples with the mass of soil particles were taken as the samples. When the moisture content soil sample is used as the sample, the required wet soil mass is calculated as follows:
4. Pour the prepared sample into the Erlenmeyer flask, inject about 200cm3 of water, soak it for more than 18 hours, and use the soil sample with natural moisture content to directly conduct the particle analysis test, without soaking or shorten the soaking time. After a little shaking, bring to a boil on a sand bath. Time from the time of boiling, clay and soil that is not easy to disperse, boil for about 1 hour, and other soils should not be less than 0.5 hours;
5. After the soil densitometer sample is cooled, pour it into the measuring cylinder used for the particle test, wash the soil in the beaker and pour it into the measuring cylinder, add 10cm3 of dispersant and then add 1000cm3 of clean water;
6. Use a stirrer to stir up and down the entire suspension depth in the measuring cylinder for about 1 min, reciprocating 30 times each, so that the soil particles in the suspension are evenly distributed;
7. Take out the stirrer, start the stopwatch at the same time, and measure the density meter readings at 1, 2, 5, 15, 30, 60, 120, and 1440min. Type B densitometer is recorded as, type A densitometer is recorded as. Put the density meter into the graduated cylinder about 15 seconds before each measurement, and take out the density meter after reading. When reading, pay attention that the density meter float should not be close to the wall of the measuring cylinder, and the reading is the reading of the rising point of the meniscus. A hydrometer is estimated to 0.1, and B is estimated to 0.0001. After reading, measure the temperature of the suspension to 0.5°C;

Details Images
Densitometer test equipment includes:
1. There are two types of density meters commonly used:
(1) Type A density meter, the scale unit is the number of grams of the mass of soil particles contained in each 1000cm3 suspension at 20°C, from 0 to 60 (or -5 to 50), and the division unit is 1.0 (or 0.5);
(2) B density meter, the scale unit is the specific gravity of the suspension at 20°C; from 0.995~1.050 (or 0.995~1.030), take the small division as 0.001 (or 0.0002), and the accuracy is 0.0002 (or 0.00005), but It is difficult to read a density meter with a division of 0.0002;
2. Measuring cylinder Effective volume 1000cm3, inner diameter 60mm, height 450mm;
3. Analytical balance In addition to the same as the sieve analysis method, an analytical balance is required; weighing 200g, the sense is 0.01g;
4. Auxiliary equipment In addition to all the auxiliary equipment of the sieve analysis method, the auxiliary equipment also needs a thermometer, a stirrer, a boiling equipment (sand bath), a dispersant, pure water, a stopwatch, etc.
