Automatic Densitometer U-shaped Vibrating Tube Method Relative
Density Hydrometer Gravity Tester High Accuracy Density Meter
Product Introduction
The automatic densitometer adopts the principle of U-tube
oscillation method, effectively combines Palter's precise
temperature control technology and high-definition video camera
technology, which not only provides users with accurate, stable and
reliable test results, but also brings users an efficient and
convenient test experience. Hd video can easily see whether there
is a bubble in the sample, the use of pulse excitation,
high-precision detection technology, convenient for users to
accurately and quickly measure the sample density and
density-related parameters.
Test principle: Inject a small amount of sample into a sample tube
that can control the temperature, record the vibration frequency or
period, and calculate the density of the sample with the sample
tube constant obtained in advance. The sample tube constant is
determined by the vibration frequency of the sample tube when it is
filled with a known density calibration fluid. The instrument
displays the density value directly after the sample is injected
into the sample tube.
Main features
1. The density meter has high measuring accuracy, fast measuring
speed and small sample quantity
2. Built-in sampling pump, automatic sampling, cleaning and drying
measuring tank
3. Hd video camera technology, easy to directly observe the
measurement pool
4. Smooth joint, will not produce bubbles and pollution, easy to
clean
5. Input the comparison table of density and concentration to
convert the concentration of the sample
6. Comply with GLP specifications, store results, checks and
correction records
7. Built-in thermal printer, can customize the sample name, company
and other information
8. Built-in drying and blowing pump, which can automatically dry
the sample tube after each cleaning
