GI-700 series

Stack Gas Analyzer

Increase your CEMS Capabilities with a HORIBA Multi-gas Analyzer

Experience HORIBA, the Global Single Source Solutions Provider with over 50 years of technological advancements and unparalleled reliability, dependability and operability.The GI-700 stack gas analyzer is designed to continuously measure the concentrations of nitrogen oxides (NO_x), sulfur dioxide (SO₂), carbon monoxide (CO), carbon dioxide (CO₂), oxygen (O₂), and ammonia (NH₃) in stack flue gas streams.

Segment: Process And Environmental

Division: Combustion

Manufacturing Company: HORIBA, Ltd.

Ultimate Dependability
Proven cross-flow modulation technique
Continuous base line validation
Ultimate Low cost ownership
Up to 6 gases can be measured using a single analyzer with multiple detectors. Works with a simple sampling unit having less tubing, fewer power cables. Simplified wiring translates into less time required for installation. Minimum function for the operation. Any additional functions can be added from controlling PLC.
Ultimate Sensitivity
5 ppm High-Precision measurement (NO_x, SO₂ and CO) is available.
Others
- An external converter provides for separate measurements of NO and NO₂.
- All component modules can be easily installed with in a single 19 inch case. The compact design saves space, facilitates maintenance and requires less wiring and tubing during installation.
- Power consumption is reduced by approximately 50% as compared to systems using individual analyzers (NH₃ analyzer).
User Friendly
Various Applications include:
Stack emission monitoring, SCR control, Desulfurization control, Greenhouse gas monitoring, Boiler emissions measurements, Gas separation, Coal and gas fired emission sources, incinerator emissions monitoring...
