BD-D1177-041AZ Fully automatic engine coolant freezing point tester is specially used to determine the freezing point of engine coolant and its concentrate.
1. BD-D1177-041AZ Fully automatic engine coolant freezing point tester obtained a utility model patent (patent number: ZL.201621462077.1)
2. BD-D1177-041AZ Fully automatic engine coolant freezing point tester is a fully automatic measuring instrument. You only need to set the corresponding parameters (such as cold bath temperature) before the experiment, and you can complete all experimental steps (such as temperature control, etc.) by yourself. It is also equipped with a printer to facilitate printing of experimental results. .
3. The control system of the instrument uses advanced PLC (programmable logic controller) as the control core. Compared with similar instruments using microcontrollers as the core, it has great advantages in stability and accuracy. In addition: PLC is also often used in machinery that requires very low failure rates, such as launch vehicles, etc.
4. The instrument is equipped with an advanced 10-inch full-color, high-performance, high-definition TFT LCD touch screen, which is sensitive to touch and reliable in quality. Parameter settings before the experiment, monitoring during the automatic experiment, and display of relevant experimental data (such as real-time cooling curves) can all be realized on the touch screen. The layout of the touch screen adopts a humanized design, and all functions are clear at a glance.
5. The instrument refrigeration system adopts a cascade refrigeration system, which has fast cooling speed, low noise and no need for cooling water. Its main components are all imported from abroad, including: German compressor, Italian refrigerant, Canadian fan condenser, etc. The lowest temperature can reach -70°C.
6. The instrument will automatically prompt at the end of the experiment or when a malfunction occurs.
7. The instrument can automatically save 10,000 sets of experimental data for easy query and export in the future.
8. The cold bath of the instrument uses an evacuated glass Dewar (with a glass protective cover on the outer layer) and a double-hole design.
9. The instrument can conduct experiments on two samples at the same time and control them independently without interfering with each other.
10. The cooling speed of the instrument: the time from 35℃ to -70℃ shall be less than or less than 100 minutes.
11. The bottom of the instrument is equipped with universal wheels for easy movement.
