UV Optical Fiber Spectrum Analyzer -- OMA-3000 -Image

The OMA-3000 Online UV Optical Fiber Spectrum Analyzer is a product that can be applied to high precision online measurement of gas concentration, such as SO2, NO, NO2, H2S, and Cl2 and etc.

The OMA-3000 can be extensively applied to system industry process, environment protection and etc.

Measurement Principle

UV light from lamp-house pool into fiber and then are transmitted to the flow cell. After absorbed by measured gas in the flow cell, they are transmitted to spectrometer via fiber and decomposed via grating. And then optical signal is converted to electronic signal by array sensor and get the spectroscopy information.

System Feature

  • The OMA-3000 System is a new generation analyzer basing on holographic grating spectrum
  • technology and differential optical absorption spectroscopy analysis technology, the whole analyzer is stable and reliable, with high performance index, long service life, convenient operation, and low workload on maintenance and calibration. This analyzer has the following features:

High measurement precision

  • The OMA-3000 uses UV difference technology, solves effectively the interference of water, dust etc on measurement precision.

High reliability

  • The gas analyzer uses light source with long service life.
  • The OMA-3000 uses holographic grating spectrum and sensor array technology, with no moving parts.

Easy maintenance, low maintenance cost

  • The analyzer is with automatic and manual calibration and zero adjustment functions.
  • The light source, flow cell and spectrometer of OMA-3000 are connected with each other by optical fibers; the components are modularized, easy maintenance and renewal.
  • Possess the ability of PLC to control the exterior magnetic valve.
  • Ample user interboard. 1.6 Operation Notice
  • The gas that enters the analyzer must be no oil, no water.
  • The gas flux that enters the analyzer should be controlled as (1-3) L/min.
  • Confirm the gas path air proof.
