Product catalog summary
Overview: The SG750 Stack Gas Analyzer is designed for continuous monitoring of flue gas concentrations from industrial sources such as boilers and incinerators. It measures up to five gas components: NOX, SO2, CO, CO2, and O2 using infrared and zirconia methods.
Measurement Principles: The analyzer employs a dual beam non-dispersive infrared (NDIR) method for NOX, SO2, CO, and CO2, and a zirconia or paramagnetic method for O2. The infrared method detects gas concentrations by measuring the infrared light absorbed by the sample gas.
Features: The SG750 offers high sensitivity and stability, with interference compensation to minimize cross-sensitivity between different gas components. It supports automatic calibration and has a wide dynamic range with switchable measurement ranges.
Applications: Suitable for use in garbage and industrial refuse incinerators, gas boilers, sludge burning, oil/coal boilers, and iron and steel heating furnaces.
Specifications: The analyzer can measure NOX from 0-50 ppm to 0-5000 ppm, SO2 from 0-100 ppm to 0-1000 ppm, CO2 from 0-10 vol% to 0-20 vol%, CO from 0-50 ppm to 0-5000 ppm, and O2 from 0-10/0-25 vol%. It provides outputs in 4-20 mA DC or 0-1 V DC formats.
Installation and Operation: The system is designed for outdoor or indoor use, with a rainproof construction. It requires a power supply of 100/110/115/200/230 V AC and consumes approximately 600 VA. The ambient operating temperature ranges from -5 to 40°C, with specific versions available for colder climates.
Performance Characteristics: The analyzer offers repeatability of ±0.5% of full scale, linearity of ±1.0% of full scale, and a 90% response time of approximately 4 minutes for SO2 and 2 minutes for other gases. Warm-up time is approximately 4 hours.
Maintenance and Calibration: The SG750 features automatic zero and span calibration, with calibration intervals adjustable from 1 to 99 hours or 1 to 40 days. Calibration gas flow time is adjustable from 60 to 599 seconds.
