INESA WMD-430 automatic density meter U-tube vibration principle 2~ 3ml injection

Product principle

• Shanghai Instrument Electro-Optical Automatic Density Meter adopts the U-tube vibration principle for detection. Simply inject a small amount of sample (2∽3ml) into the U-shaped vibrating tube, depending on the vibration frequency of the U-shaped tube combined with calibration data to quickly measure the density of liquid samples. 

• WMD series automatic video densitometer, compared with the traditional volumetric method, hydrometer method and balance densitometer method to measure the density and relative density of liquids, has less sample consumption and is quick to use It has the characteristics of high measurement accuracy and good repeatability of indication value.

Features

• Operation interface: color Android touch screen display, high-definition camera video detection is more intuitive and convenient

• Small injection volume: only 2~3ml of the sample to be tested needs to be consumed for each measurement, saving resources and reducing costs

• Measurement modes: Built-in density, relative density, general, chemical, petroleum and other measurement modes

• Temperature control: Built-in Peltier temperature control device, accurate measurement of sample density can be achieved under precise temperature control

• Rapid detection: You can choose the density rapid pre-test mode or accurate measurement mode, which is convenient for customers to use

• Instrument calibration: Error verification is simple, and the instrument can be calibrated with only dry air and distilled water

• Communication interface: Built-in network module, equipped with a variety of communication interfaces, data can be saved, exported and printed

• User management: four levels of user management authority, data reporting, electronic signature, and optional audit trail function
