The Electronic Liquid Densimeter ZGMD50, based on the U-tube Oscillation Method, provides precise and high-sensitivity liquid density measurements. Utilizing a microprocessor-controlled system, it detects oscillation frequency variations in a U-type tube filled with different media. This fully automatic instrument features an advanced density sensor, temperature control, and self-cleaning system. It is ideal for applications in industries such as petroleum, chemicals, beverages, alcohol production, and pharmaceuticals. It can also calculate concentrations for alcohol and sulfuric acid solutions.

U-tube Vibration Principle: Ensures fast, sensitive, and accurate density measurements.
High-Performance Processor: Uses imported ZGMD chip for precise data processing.
Automatic Sampling: Features an auto-quantifying injection system for minimal sample loss.
Residue-Free Cleaning: Self-developed technology eliminates liquid residue, maintaining accuracy.
Advanced Temperature Control: Peltier cooling system ensures efficient, eco-friendly temperature regulation.
Wall-Free Inner Tube Design: Prevents inner wall liquid retention, enhancing measurement precision.
Data Management: Internal memory stores up to 80 test results, supports retrieval and deletion.
Calibration Function: Allows internal calibration using 20℃ pure water – surpassing traditional glass density meters.
Built-in Environmental Monitoring: Integrated temperature and humidity sensors for intelligent operation.
The ZGMD50 Electronic Liquid Densimeter is widely used for precise density measurement across various liquid samples in industrial and laboratory settings. Its high accuracy and automatic temperature control make it ideal for applications such as:
Petroleum and Petrochemicals: Measurement of crude oil, diesel, lubrication fluids, and cleaning agents.
Chemical Industry: Testing of chemical reagents, solvents (e.g., benzene, toluene), and specialty liquids.
Food and Beverage: Quality control of alcohol, beverages, and essential oils.
Fragrance and Cosmetics: Density testing of essences, spices, and aromatic oils.
Welding and Manufacturing: Measurement of welding flux and other process liquids.
Insert the injection tube into the liquid sample.
Press the “Sample” button to start automatic liquid intake.
The liquid will be pumped into the measurement cylinder automatically.
Wait for the system to reach a constant temperature of 20 ± 0.1℃.
The LED display will automatically show the real-time density and temperature of the sample.
Drain the tested liquid completely from the cylinder.
Rinse the cylinder with a suitable cleaning solution.
Repeat rinsing until no residue remains in the measuring chamber.
