Mineral rockBulk density tester
Applicable to:Mineral mining industry, geological research laboratory
According to the criteria; According to ASTM C39, ASTM C128, ASTM C127, AASHTOT 84, JIS, GB/T23561 specifications. Adopting Archimedes' principle and buoyancy method, applying vacuum saturation method, boiling saturation method, particle immersion method to quickly read measurement values.
Three density measurement modes:
Mode 1: For non absorbent materials, density and volume can be directly read;
Mode 2: Directly read bulk density, wet density, apparent density, apparent porosity, water absorption, open pore volume, sealed pore volume, and total porosity
Mode 3: The wax sealing method can directly read the bulk density and volume.
Mode 4: The water absorption rate of the absorbent material can be directly read.
Specification: (The following three methods can be used to measure product density using silicone oil method. If mercury method is required, please contact the supplier)

The measurement steps of saturation method density:
① Place the sample on the measuring table, measure the weight in the air, and press the M key to memorize.
② After saturating the sample, place it on the measuring table, measure the weight in the air, and press the M key to memorize.
③ After saturating the sample, place it in water, measure the weight in the water, press the M key to memorize, and directly display the density value.
Press 0 to switch between displaying wet density, apparent porosity, water absorption, open pore volume, closed pore volume, and total porosity.
Measurement steps for density of non absorbent materials:
① Place the sample on the measuring table, measure the weight in the air, and press the M key to memorize.
② Immerse the sample completely in water, measure the weight in water, press the M key to memorize, and directly display the density value.
Measurement steps for density of porous materials using wax sealing method:
① Place the sample on the measuring table, measure the weight in the air, and press the M key to memorize.
② Place the sample in the wax oven and seal it with wax before placing it on the measuring table. Measure the weight in the air and press the M key to memorize.
③ Put the sealed wax sample into water, measure the weight in the water, press the M key to remember, and directly display the density value. Press 0 to switch the display volume.
