Thermostatic Electronic Liquid Densitometer

Thermostatic Electronic Liquid Densitometer 

Product Introduction

Electronic liquid density meter can be widely used in all kinds of liquid density measurement, has been in the biochemical, pharmaceutical, chemical, oil refining, environmental protection, food, wine, pharmaceutical, oil and food and beverage processing and other fields is widely used, but also can be used for the quantitative packaging of quality and technical supervision system test as well as the colleges and universities laboratory use. Can be widely used in all kinds of liquid density measurement, and cooperate with different concentration conversion software, can directly read out the corresponding liquid density, such as alcohol, by single-chip microcomputer software processing, can be directly read data volume concentration, the test is more convenient.

The constant temperature electronic liquid density meter is used to measure the liquid density according to the principle that the oscillation frequency is different when the double U tube is filled with different media.After the liquid to be tested is pumped into the resonant cylinder sensor, the measurement data is processed by SCM, which is fast and direct, and has high sensitivity.It is composed of double tuning fork density sensor, vibrator circuit, temperature measuring circuit, CPU, display, constant temperature slot, liquid inlet pump and control panel.It changes the traditional method of measuring liquid density by glass densitometer, which makes liquid density measurement more accurate, rapid and economical.

Principle:Electronic liquid density meter conforms to GB/T29617,ISO12185, ASTM D4052 / D5002, GB/T29617-2013, GB/T2013-2010, GB23971-2009, GB4747-2009, SH/T0604-2000, SN/T2383-2009, SH/T0729-2004, ASTMD4052, ASTMD5002, ASTM D1250, ASTM D3505, ISO 12185:1996 specification.

Thermostatic Electronic Liquid Densitometer

Product Features:

1. Constant temperature control: The sensor, its components and sample liquid are sealed in the constant temperature tank under the control of the constant temperature tank. The temperature of the oscillating tube (sample liquid) is detected by the temperature sensor.

2. Directly display the density value of liquid at 20℃ with temperature display window.

3. Automatic sampling: The stepper motor is controlled by single chip microcomputer to drive the peristaltic pump to suck samples, which improves the degree of automation of the product

4..Data storage and transmission: the built-in memory chip can store 80 sets of detection data, and can be recalled and deleted.It can be connected to the computer through 232 interface according to user's requirement.

5. Calibration function: Pure water at 20℃ is used as the standard to calibrate the instrument, which cannot be achieved by glass densitometer.

Product Advantages:

1. Measuring range: One instrument can directly measure the liquid density in the density section of 0~1999.99kg/m3.

2. Small comprehensive error: Because many error factors are reduced, the comprehensive error of the instrument is reduced.

3. Small workload: Reduced workload due to the absence of conversion and other work.

4. Resource saving: The sample volume is only 2ml each time, which reduces the waste of sample liquid resources.

5. High degree of automation: peristaltic pump automatic injection, self-calibration.

6. High cost performance: the quality can be comparable with foreign similar products, the price is only one eighth of the foreign similar products.

Test steps:

Insert the inlet tube into the sample, press the "sample" button, and the sample will be sucked into the vibrator by the inlet pump. After constant temperature, the density of the liquid will be displayed directly after alarm.
