The fully automatic liquid densimeter adopts the principle of U-tube oscillation method, effectively combines Peltier accurate 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 efficient and convenient test experience.
High-definition video can be convenient to see whether there are bubbles in the sample. Pulse excitation and high-precision detection technology are convenient for users to accurately and quickly measure the sample density and density related parameters.
Test Principle: inject a small amount of samples into the sample tube with controlled temperature, record the vibration frequency or period, and calculate the density of the sample with the sample tube constant obtained in advance. The tube constant is determined by the vibration frequency when the tube is filled with known density calibration fluid. The instrument displays the density values directly after the sample is injected into the sample tube.
Main Characteristics:
1.High density meter measurement accuracy, fast measurement speed, small sample volume.
2. Built-in injection pump, automatic sampling, cleaning and drying measuring pool.
3. High-definition video camera technology for conveniently and directly observing measuring pool.
4. Stainless steel joint will not cause bubbles and contamination, easy cleaning.
5. Input comparison table of density and concentration to convert concentration of samples.
6. Comply with GLP requirement, storing test results, inspecting and correcting records.
7. Built-in thermal printer, can customize the printing sample name, company and other information.
8. Built-in drying air pump, each cleaning can automatically dry the sample tubes.
