The siphon cylinder gravimeter is suitable for soils having a particle diameter greater than or equal to 5 mm, and the content of the soil having a particle diameter of 20 mm is greater than or equal to 10% of the total soil quality.
Siphon tube gravimeter technical parameters:
★Siphon tube device, consisting of a siphon tube and a siphon tube.
★ Taiwan scale: weighing 10Kg, A small division value of 1g.
★ Measuring cylinder: the volume should be greater than 2000mL.
★ Weight: 10kg
Siphon tube gravimeter test steps
★ Take a representative sample of 700-1000G, the sample should be cleaned until the surface of the particles is free of dust and other contaminants.
★ Immerse the sample in water for a whole day and then take it out to dry. For large particle samples, dry the surface with a dry cloth and weigh the sample.
★Inject the clean water into the siphon tube until the siphon tube has water overflow.
The siphon cylinder 4 slowly puts the sample into the siphon cylinder, and while stirring, until no air bubbles escape from the sample, the water should not splash out of the cylinder when stirring.
★ When the water surface in the siphon cylinder is stable, open the pipe clamp, let the water discharged from the sample flow into the measuring cylinder through the siphon, weigh the cylinder and the total mass of the water to the nearest 0.5G, and measure the water temperature inside the measuring cylinder to the accuracy of 0.5 °C.
★ Take out the sample and bake it to a constant amount, say the quality of the dried sample, accurate to 0.1G, weighing the cylinder, accurate to 0.5G
Siphon tube gravimeter other instruments: oven, thermometer, sieve with aperture 5mm and 20mm.
