Density/Specific Gravity Meter <DA-130N>
ASTM D7777-13(2018)e1 Standard Test Method for Density, Relative Density, or API Gravity of Liquid Petroleum by Portable Digital Density Meter.
Summary of Test Method
The test sample is brought to a temperature close to that of the density meter. If present, the density meter’s software program for calculating the density at the reference temperature is selected, and the oscillating U-tube of the density meter is filled with the test portion in accordance with the manufacturer’s instructions. After stabilizing, the density meter’s in-built software calculates the density at the reference temperature.
The apparatus’ system is regularly checked using reagent grade water.
- Sampling volume and speed is single hand controlled. (Patent pending)
- Operative either by right or left hand, the cell can be viewed during measurement.
- Light weight allows operators to feel tireless in the normal operations.
- Viscous liquid up to ca 2000 mPa･s can be sampled in.
- The display shows density, temperature compensated density, specific gravity, temperature compensated specific gravity, Brix %, alcohol concentration, sulfuric acid concentration, API degree, Baume degree, Plato and Proof degree and the like.
- Graphic LCD can display temperature, sample number, auto sensing oscillation stability, auto data saving, auto data output, data deletion, buttery capacity indicator, and the like.
- Life of battery is increased two times more than conventional makes, providing much longer operation time.
Applications:
Beverages, foods, petroleum, chemical products,pharmaceutical, alcoholic beverages, etc.
