The electronic liquid density meter can be widely used in the measurement of the density of various liquids, and has been widely used in various fields such as biochemistry, chemical industry, oil refining, environmental protection, food, winemaking, petroleum and food and beverage processing, and can also be used for quantitative packaging testing of quality and technical supervision system and laboratories of colleges and universities. It can be widely used for the measurement of the density of various liquids, and with different concentration conversion software, it can also directly read the concentration value of the corresponding liquid, such as alcohol, through the processing of the single-chip microcomputer software, the volume concentration data can be directly read, and the test is more convenient.
The thermostatic electronic liquid density meter is based on the principle of different oscillation frequencies when the double U-shaped tube is filled with different media. After the liquid to be measured is pumped into the resonator tube sensor, the measurement data is processed by a single-chip microcomputer, which is fast and direct, and has high sensitivity. It is composed of a double tuning fork density sensor, a vibrating cylinder circuit, a temperature measurement circuit, a CPU, a display, a thermostatic bath, a liquid inlet pump and a control panel. It changes the traditional method of measuring liquid density with glass density meters, making liquid density measurement more accurate, fast and economical.
The electronic liquid density meter complies with 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 specifications
Constant temperature control: the constant temperature bath control, the sensor and its parts and sample liquid are sealed in the constant temperature bath, the temperature of the oscillating tube (sample liquid) is detected through the temperature sensor, and the electronic components are controlled by the single-chip microcomputer to cool or heat to ensure that the temperature in the thermostatic bath is stable in the range of 20 °C ± 0.1 °C.
The density value of the liquid at 20°C is directly displayed, and there is a temperature display window. 3. Automatic sampling: The single-chip microcomputer controls the stepper motor to drive the peristaltic pump to suction samples, which improves the automation degree of the product 4. Data storage and transmission: The built-in storage chip can store 80 sets of detection data, and can be called back and deleted. It can be connected to the computer through the 232 interface according to the user's requirements (customized). 5. Calibration function: Use 20°C pure water as the standard to calibrate the instrument, which is a function that cannot be achieved by glass density meter.
1. Wide measuring range: one instrument can directly measure the density of liquid in the density range of 0~1999.99kg/m3.
2. Small comprehensive error: due to the reduction of many error factors, the comprehensive error of the instrument is reduced.
3. Small workload: The workload is reduced due to the absence of conversion and other work.
4. Resource saving: The amount of each sampling is only 2ml, which reduces the waste of sample resources.
5. High degree of automation: the peristaltic pump automatically fills the sample and calibrates itself.
6. Cost-effective: The quality is comparable to similar foreign products, and the price is only one-eighth of similar foreign products.
Insert the inlet tube into the liquid sample, press the "sampling" button, the sample liquid is sucked into the vibrating cylinder by the inlet pump, and the temperature is constant, and the density of the liquid is directly displayed after the alarm.
