Overview
ZDHW-9000A high-precision microcomputer fully automatic calorimeter
Product Details
1. System thermal capacity changes within 3 months＜0.15%.
2. Oxygen bombs have functions such as automatic lifting, automatic oxygenation, automatic deflation, and automatic recognition
3. Advanced compressor refrigeration and heating dual system, completely unaffected by environmental temperature changes during experiments, ensuring that the temperature difference between the inner and outer barrels of the instrument meets national standards.
4. The inner bucket water can be automatically controlled through heating and cooling (constant temperature), and can work continuously for a long time.
5. Stainless steel vacuum inner barrel to ensure stable temperature of the outer barrel.
6. The inner and outer buckets have automatic drainage without the need for manual intervention.
7. Ignition method: cotton thread and ignition wire
8. Ignition circuit short circuit protection function, ignition wire detection.
9. Microcomputer and 7-inch touch dual operating system, more convenient to use, and more timely and accurate monitoring.
10. One machine with multiple controls. You can use one computer to control 5 calorimeters.
11. Fast testing speed, fast method<10min, national standard method＜15 minutes (GB/T213-2008), precision method<20 minutes.
12. The sample code and weight information can be automatically uploaded, and the test data can be backed up, queried, and retrieved last time. The uploaded data includes: start time, ignition time, main period end time, main period temperature rise, cooling constant, comprehensive test, outer cylinder temperature, inner cylinder temperature, and all system data required for manual verification of data.
13. The software runs stably and displays data curves in real-time.
14. The data processing function is rich, and users can easily query historical experimental data, current day data, parallel sample data, etc.
15. It can be connected to a balance and a local area network, enabling data upload and multi control on one machine.
