The High-precision Solid And Liquid Densimeter is a benchtop analytical instrument that measures density of both solid and liquid materials using the Archimedes principle displacement method. With a capacity range of 0.001-120g and measurement time of approximately 5 seconds, this densimeter provides rapid density determinations and displays results as both density values and Baumé degrees. The instrument features automatic correction and detection capabilities with distilled water testing for result validation.
The densimeter allows free setting of density values for main and subordinate materials and displays both density values and percentage composition of the main material. Auto correction and detection functions ensure measurement accuracy, while optional accessories including the DE-40 printer and DE-20B anti-corrosive liquid measuring assembly extend the instrument's analytical capabilities. The compact 195×230×197mm footprint and universal AC power supply make it suitable for diverse laboratory environments.
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.
