Product Details
Single - ended Ultrasonic Flow Velocity Meter KGD - LL - 502
Product Introduction
Based on the principle of laser Raman scattering, the KGD - MQ -
502 enhances, collects, processes and identifies the characteristic
Raman scattering spectra of the measured gases, enabling
qualitative and quantitative analysis of multiple types of gases
simultaneously. The system is designed for in - situ installation
and measurement, and can conduct continuous on - line non -
destructive gas analysis of nearly 20 components at the same time.
Equipped with a Raman sampling probe, it adopts a positive -
pressure explosion - proof design, which is safe and durable. It
has a second - level response, eliminating the need for long
waiting.
Product Features
- Non - destructive gas analysis, including homonuclear diatomic
analysis (H₂, N₂, O₂).
- Capable of continuous on - line monitoring of multiple gases
simultaneously. One instrument can solve the full - process
monitoring of industrial process gases.
- Equipped with a Raman probe. There is no need to extract gas for
measurement in the instrument, and no consumables (chromatographic
columns, valves, air pumps, etc.) are required.
- The instrument has a positive - pressure explosion - proof design,
a long maintenance cycle, and high safety. Toxic and flammable
gases will not enter the analysis process.
- Intelligent software design with a full - touch screen interface.
Data is displayed intuitively, and an external PC keyboard can be
connected.
