DZY-018ZI automatic saturated vapor pressure tester Features
1. The instrument is a fully automatic instrument, just press the "Start Experiment" button after preparing the sample, the entire experiment process can be completed by yourself (including: obtaining results, recording results, printing results). Vapor pressure, and record and print the results.
2. The historical experimental data stored in the instrument can be queried, printed, and exported through the USB socket.
3. The control system of the instrument uses advanced PLC (that is, programmable logic controller) as the control core. Compared with similar instruments that use single-chip microcomputer as the core, it has great advantages in stability and accuracy. Another: PLC is also often used in machinery with very low failure rate requirements, such as carrier rockets.
4. The instrument is equipped with a 7-inch full-color, high-performance, high-definition TFT LCD touch screen, which is very sensitive to touch. All the operation and data display of the instrument can be realized on the touch screen, and the layout of the touch screen adopts humanized design, and the functions are clear at a glance.
5. The instrument has the function of displaying the time pressure curve corresponding to the vapor pressure change in the experimental bomb in real time, and the laboratory technician can intuitively understand the pressure change trend through the curve.
6. The instrument is a desktop all-in-one machine with a compact structure and a small space required; the layout is reasonable, the water bath is in front, the control box is behind, and the water drain valve is provided at the right rear of the water bath, which is convenient for changing the bath liquid.
7. The bath of the instrument is made of stainless steel with good anti-rust performance; its heating device is placed at the bottom of the bath, and the advanced powerful silent magnetic circulation pump provides a more uniform bath temperature for the experiment.
8. The instrument is designed in accordance with the improvement requirements mentioned in the national standard GB / T8017-2012, especially the water bath fully meets the requirements of horizontal placement.
9. The right side of the water bath of the instrument is equipped with a motor that can automatically change direction. During the experiment, the vapor pressure test bomb can rely on this motor to alternately rotate clockwise and counterclockwise at a rotation angle of 350 °.
10. The size of the vapor pressure test bomb equipped with the instrument and the volume ratio of the gas chamber to the liquid chamber (the volume ratio of the gas chamber to the liquid chamber are 3.8 to 4.2) fully meet the standard requirements.
11. The instrument is equipped with a high-precision and high-sensitivity pressure transmitter, which can monitor the pressure value in the vapor pressure test bomb in real time.
12. The quick pressure connector "imported from Japan" is used for the link connection between the vapor pressure test bomb of the instrument and the pressure transmitter, which has the advantages of easy insertion and removal and no hidden danger of pressure relief.
13. The instrument is equipped with a U-shaped mercury pressure differential pressure calibrator to ensure the accuracy of pressure detection.
14. The instrument is equipped with two sets of vapor pressure test bombs (can also be increased to three sets), which can measure two (or three) test samples at the same time, which improves the efficiency of the experiment.
15. According to customer needs, the instrument can be equipped with a "special cold bath for saturated vapor pressure" (this cold bath is not a standard configuration). Technical parameters
1. Instrument power supply: AC220V ± 10% 50Hz standard 10A plug
2. Heating power: 2KW
3. Temperature control range: room temperature ~ 37.8 ℃
4. Temperature control accuracy: ± 0.1 ℃
5. Pressure measurement range: 0kpa ～ 160kpa
6. Pressure measurement accuracy: ± 2 ‰
7. Volume ratio of gas chamber to liquid chamber: 4: 1
