Flue gas analyzer

Ultrasonic – Flowneter

TDLS – CO

• Utilizes tunable diode ;aser (TDL)technology to scan a narrow wavelength range, unaffected by gases other than CO
• Semi-permanent use without light source replacement using a laser light source
• Enables standard gas calibration with calibration filters
• Incorporates SUS material in calibration filters to prevent damage from duct-related particles like dust and sand

TDLS – NH₃

• Utilizes tunable diode laser (TDL) technology to scan a narrow wavelength range, unaffected by gases other than NH₃
• Semi-permanent use without light source replacement using a laser light source
• Enables standard gas calibration with calibration filter
• Incorporates SUS material in calibration filters to prevent damage from duct-related particles like dust and sand
• Simultaneous H2O measurement enables moisture correction

UV Absorption / Zirconia – NOx, SO₂, O₂

• Integrates DGA-X and GGA-70-1 to simultaneously measure NOx, SO₂ and O₂
• NOx and SO₂ measurements employ ultraviolet differential optical absorption spectroscopy (UV DOAS), while O₂ uses zirconia sensing method
• Optional addition of a standard gas calibration device

UV Absorption – NOx, SO₂, NH₃

• Explosion-proof model of the DGA-X
• In-situ explosion-proof design reduces the need for a explosion-proof shelter, saving costs and minimizing space constraints
• Measures in the low wavelength UV range (200 ~ 400 nm) for high precision and minimal moisture interference
• Utilizes the differential optical absorption spectroscopy (DOAS) method, eliminating the need for calibration
• Selectively measures two gases out of NOx, SO₂, and NH₃ simultaneously
• Enables individual NO and NO₂ measurements without the need for a
