Overview
WMD-350 automatic density meter is a precision detection instrument using the vibration principle of U-shaped tube of INESA brand. The instrument can quickly measure liquid density, relative density and other parameters with only 2~ 3ml sample. Compared with traditional methods, it has the advantages of less sample consumption, convenient operation, high measurement Precision and good Repeatability.
Features
1. Operation interface: color Android touch screen display, high definition camera video detection is more intuitive and convenient
Small injection volume: each measurement only needs to consume 2~ 3ml of samples to be tested, saving resources and reducing costs
3. Measurement mode: Built-in density, relative density, general purpose, chemical, petroleum and other Measurement modes
4. Temperature control: built-in Peltier temperature control device, precise temperature control can achieve accurate measurement of sample density
5. Fast detection: You can choose density fast pre-test mode or accurate Measurement mode, which is convenient for customers to use
6. Instrument calibrating: error calibration is simple, just use drying air and distillation water to calibrate the instrument
7. Communication interface: built-in network module, equipped with a variety of communication interfaces, data can be saved, exported and printed
8. User management: four levels of user management authority, data reporting, electronic signature, optional audit tracking function
Principle
The automatic density meter adopts the vibration principle of U-shaped tube for detection. A small amount of samples are injected into the U-shaped vibrating tube, and the density of the liquid sample is quickly measured according to the change of the vibration frequency of the U-shaped tube and combined with the calibration data. Compared with the traditional capacity method, the specific gravity meter method and the Balance Density Meter method, it has the characteristics of less sample consumption, fast and convenient use, high measurement Precision and good indication Repeatability.
Applications
Beverage industry, food industry, brewing industry, petrochemical industry, chemical industry, flavors and fragrances, machinery manufacturing, inspection agencies

Steps
1. Instrument calibrating: use drying air and distillation water to calibrate
2. Sample injection: Inject 2~ 3ml of the sample to be tested into a U-shaped vibrating tube
3. Mode selection: Select density quick pre-check mode or accurate Measurement mode as needed
4. Temperature setting: Set the required temperature through the Peltier temperature control device
5. Start measurement: Start the measurement program, the instrument automatically detects and displays the results
6. Data management: Data can be saved, exported, and printed through touch screen operation
Notice
• The sample injection amount should be controlled within the range of 2~ 3ml
• Make sure to use drying air and distillation water when calibrating
• Confirm that the temperature control setting is correct before measurement
• The U-shaped vibrating tube should be cleaned in time after use
• Please confirm that the storage space is sufficient before exporting the data
• The operation should follow the four-level user management authority regulations
