Product Description

Introduction:

This instrument is designed according to the principle of different oscillation frequency when two U-tube is filled with different media(U-tube oscillation method). After pumping the liquid to be measured into the resonator sensor, the measurement data are processed by the single chip computer, which is fast, direct and sensitive. It is composed of a double tuning fork density sensor, a vibrator circuit, a temperature measuring circuit, a CPU, a display, a thermostat, an intake pump and a control panel.

 

Scope of application:

petroleum, diesel oil, washing liquid, lubricating fluid, chemical liquid, flux, crude oil, chemical reagent, stupid, toluene, essence and spice, essential oil. Density testing in alcoholic and beverage industries, for alcohol and sulphuric acid solutions,it can be converted to concentration.

 

Applied Standards:

GB/T29617,ISO12185,ASTMD4052/D5002,GB/T29617-2013,GB/T2013-2010,GB23971-2009,GB4747-2009,SH/T0604-2000,SN/T2383-2009,SH/T0729-2004,ASTMD4052,ASTMD5002,ASTMD1250,ASTMD3505,ISO12185:1996

Dimension (length x width x height) 206 mm *205 mm *200 mm

Weight: 3.6kg

Power supply: 220V ± 22V, 50Hz ± 1Hz, 50VA

Display screen LED display

Data storage capacity: 80 measurements in memory

Other special functions: built-in temperature and humidity sensors for intelligent environmental monitoring

 

 

Features:

1. Using the principle of U-tube vibration method, it is suitable for automatic density measurement of liquids.

2. Imported high-speed XFMD chip processing, high sensitivity, accurate data

3. Automatic Sampling: Using the special automatic sampling system for male hair, automatic quantitative technology, high accuracy.

4. Removal of residues by self-developed technology to ensure no residues in samples

5. Constant temperature control: using self-developed Peltier refrigeration technology, high refrigeration efficiency, environmental protection

6. wall-free treatment: liquid will leave residual liquid on the inner wall of oscillating tube in the process of flow, which will affect the measurement accuracy. Therefore, wall-free treatment on the inner wall of oscillating tube can avoid residual liquid on the inner wall of oscillating tube and ensure the accuracy of the instrument.

7. Data storage and transmission: Built-in memory chip can store 80 sets of test data, and can be callback and deleted.

8. Calibration function: The instrument is calibrated by using pure water at 20°C as standard, which is a function that glass densitometer can not achieve.

 

Testing steps:

Insert the sample tube into the liquid, press the "Sampling" button, and the liquid will be automatically pumped into the vibrating cylinder. The temperature and density of the liquid will be displayed directly on the screen when the machine is kept at 20±0.1 °C

 

Automatic cleaning:

The liquid in the vibrating cylinder should be drained first, and then clean the vibrating cylinder with suitable cleaning liquid until no residue is seen in the vibrating cylinder.
