The BK-DME solid and liquid densimeter measures the density of both solid materials and liquids, supporting quality management, cost control, formula research, and material studies. Measurement is based on Archimedes principle. Water temperature compensation and solution compensation functions ensure accuracy across varying conditions. For volatile, corrosive, or strong acid/base liquids, the optional DE-20B anti-corrosive assembly is required.

How It Works
The densimeter operates on Archimedes principle, which states that the buoyant force on a submerged object equals the weight of the displaced fluid. For solid samples, the instrument measures the sample's weight in air and then its apparent weight when submerged in a reference liquid (typically distilled water). The density is calculated from the difference between these two measurements, accounting for the known density of the reference liquid and environmental conditions.
For liquid measurements, the displacement method involves measuring the volume displaced by a known mass of sample or using a calibrated sinker of known volume. The instrument's measurement system automatically corrects for temperature variations and provides rapid density determinations within approximately 5 seconds. Distilled water testing validates measurement accuracy, while the auto-detection function ensures proper measurement conditions are maintained throughout the analysis.

Practical Tips
Perform distilled water testing at the beginning of each analytical session to verify measurement accuracy.
Why: Environmental conditions can drift throughout the day, affecting measurement precision.
Clean measurement surfaces with appropriate solvents and dry thoroughly between different sample types.
Why: Residual contamination can bias density measurements and affect subsequent analyses.
Allow samples to equilibrate to room temperature before measurement to minimize thermal effects.
Why: Temperature variations affect both sample density and the reference liquid properties.
Remove all air bubbles from liquid samples using gentle agitation or vacuum degassing.
Why: Trapped air reduces apparent density and creates measurement errors in displacement calculations.
Perform multiple measurements on critical samples and calculate average values for improved precision.
Why: Replicate measurements help identify outliers and improve statistical confidence in results.
If measurements show excessive drift, check for vibration sources and air currents around the instrument.
Why: External disturbances can affect the sensitive measurement balance and cause inconsistent results.
Use appropriate personal protective equipment when handling corrosive samples with the anti-corrosive assembly.
Why: Chemical compatibility accessories protect the instrument but do not eliminate operator exposure risks.

Compliance
What is the difference between the BB-BK-DME300D and BB-BK-DME600D?
The only difference is weighing capacity. The DME300D handles samples from 0.005 g to 300 g, while the DME600D extends to 600 g. All other specs — density range, resolution, measurement time, dimensions, and accessories — are identical.
What types of samples can this densimeter measure?
The instrument measures both solid samples (granules, pellets, powder compacts, gems, minerals, polymers) and liquids. For solids it uses the Archimedes immersion method; for liquids it uses a dedicated floating body or liquid measuring assembly.
Does the instrument compensate for liquid temperature?
Yes. The densimeter includes automatic water temperature compensation and solution compensation to correct for variations in liquid density caused by temperature changes, improving accuracy without manual correction tables.
Can results be exported to a computer or printer?
Yes. The instrument includes an RS-232C interface for data transfer to a PC. An optional DE-40 thermal printer can also be connected for direct printouts.
What is included in the standard accessory package?
Standard accessories include: tweezers, thermometer, 100 g calibration weight, windshield, power transformer, measuring tank, testing board, particle measuring assembly, floating body assembly, measuring plate, and DE-20A standard liquid measuring assembly. Optional extras include the DE-40 printer and DE-20B anti-corrosive assembly.
