Full spectrum measurement and DOAS (Differential Optical Absorption Spectroscopy) algorithm, excelling in accuracy, repeatability and anti-interference with moisture, dust.
Modular design and no moving parts, higher reliability and easier maintenance.
Pulse Xenon Lamp used as light source with over 10-year lifetime.
The adoption of diode array sensor enables instant spectrum acquisition and rapid response.
>>> Features and Benefits
1) The light source emits ultraviolet beam which transfers to gas cell through optical fiber.
2) After absorption by measuring gas, the light beam transfers through optical fiber to spectrometer.
3) Being dispersed through the grating, and converted into electric signal by the array sensor, a continuous absorption spectrum of measuring gas is thereafter obtained.
| Item | UV Hot-Wet Method | NDIR |
| Spectral Range | Complete and continuous absorption spectra obtained through holographic grating and diode array detection | Non Dispersive, characteristic absorption spectra obtained through band-pass filter |
| Linear Response | High wavelength resolution secures linear response | band-pass filtration compromises linear response |
| SO2 Loss | Hot-wet prohibits SO2 dissolution | Condensation inevitably causes SO2 loss |
| Sampling System | Heat tracing. Requests only dust filtration, simple and no corrosive | Cold-dry. Requests dust filtration, condensation, water removal and corrosion proof |
| Zero Calibration Period | Long (DOAS algorithm) | Short |
| Anti-Interference | The combination of complete & continuous absorption spectra, high wavelength resolution, DAOS algorithm erases interference from dust, moisture and background gases | Vulnerable to moisture interference |
| Gas Cell | Connected by optical fiber, easy to replace and low maintenance cost | Complex to replace and maintenance |
