Product Introduction:
1、 Performance Introduction
ZX-7900 Online Gas Analyzer System
The ZX-7900 online gas analyzer system produced by our company is designed to meet the needs of gas detection automation. It adopts the characteristics of imported instruments in instrument manufacturing, with the original intention of being fully automatic, minimizing personnel operation, and ensuring stable, continuous, and long-term use of the instrument as much as possible. Can handle mine gas and atmospheric pressure 24-hour continuous online monitoring and analysis of gases such as natural gas and environmental waste gas emissions from negative pressure pipelines.
2、 Instrument features
1. Adopting advanced international automatic control technology to maintain long-term stable operation,
2. Automatic sampling adopts advanced solenoid valves and stepper motor control, which is accurate, reliable, and has a long service life,
3. Adopting dual time control injection, it can be adjusted in real-time as needed,
4. The analysis report has automatic display, automatic storage, and can be freely accessed and printed,
5. The workstation reverse control operation has increased the intelligence analysis of the instrument and improved the repeatability of instrument analysis,
6. An independent pneumatic control system ensures that various analyses do not interfere with each other,
7. Specially superior online analysis function, capable of real-time testing of product quality.
