Product Description

Item: Electronic liquid density meter    
Model: PT-4052

U-tube oscillating density meter, electronic liquid density meter is based on the principle of different oscillating frequency when the double U-tube is filled with different media. After pumping the sample into the resonance tube sensor, the measurement data is processed by the single chip microcomputer, it features fast direct, and has high sensitivity. It consists of a dual tuning fork density sensor, vibrating tube circuit, temperature measuring circuit, CPU, display, constant temperature bath, liquid inlet pump and control panel.
applications: petroleum, diesel, cleaning fluids, lubricating fluids, chemical liquids, fluxes, crude oils, chemical reagents, stupid, toluene, flavors, essential oils, alcohol, beverages, etc. Density testing for alcohol and sulfuric acid solutions, can convert the concentration.
Applicable standard: 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

Features:
1. Constant temperature control: The thermostat is used to control the sensor, its components and sample liquid in the constant temperature tank. The temperature sensor detects the temperature of the oscillation tube (sample liquid). The temperature in the constant temperature bath is stable within the range of 20 ° C ± 0.1 ° C.
2. Directly display the density value of the liquid at 20 ºC, and have a temperature display window.
3. Automatic sampling: adopting single-chip microcomputer to control stepper motor to drive the peristaltic pump to suck samples, which improves the degree of automation
4. Data storage and transmission: Built-in storage chip, can store 80 sets of test data, and can be recalled and deleted. Can be connected to the computer through the 232 interfaces according to user requirements (customized).
5. Calibration function: Calibrate the instrument by 20 ºC pure water as a standard which is not available for glass densitometer.

Advantage:
1. Measuring range width: One instrument can directly measure the liquid density of the density range of 0 ~ 1999.99kg / m3.
2. Small comprehensive error: Because many error factors are reduced, the overall error of the instrument is reduced.
3. Small workload: Because there is no work such as conversion, the workload is reduced.
4. Save resources: each sample volume is only 2ml, which reduces the waste of sample liquid resources.
5. High degree of automation: automatic injection of peristaltic pump, self-calibration.

Test steps:
Insert the liquid inlet tube into the liquid sample and press the "Sampling" key. The sample liquid is sucked into the vibration cylinder by the liquid inlet pump. After the temperature is constant, the density of the liquid is displayed directly after the alarm.

1. Density measurement range: 0 ~ 1.9999g / cm3
2. Density accuracy: ± 0.0005g / cm3
3. Sampling capacity: about 2ml for each injection (automatic injection and manual injection);
4. Ambient temperature: 5 ºC ~ 35 ºC;
5. Temperature control function: Constant temperature of the measured sample to 20 ± 0.1 ºC
6. Data storage capacity: up to 80 sets of data, density value or concentration value;
7. Power supply: 220V ± 22V, 50Hz ± 1Hz, 50VA.
8. Automatic calibration: Use pure water at 20 ºC as calibration
9. Cleaning function: automatic cleaning
