Application Scope
The TH-890D ultraviolet flue gas analyzer is a portable instrument based on ultraviolet differential absorption spectroscopy (DOAS) technology, mainly used to measure concentrations of gases such as SO₂, NO, NO₂, O₂ in flue gas from fixed pollution sources. It can be used by environmental monitoring departments to measure gas concentrations and emissions from boiler exhaust, and can also be used by industrial and mining enterprises to measure various harmful gases.
Instrument Features
•Portable design, suitable for environmental monitoring departments to test gas concentrations and emissions from various boilers, and can also be applied by industrial and mining enterprises to measure concentrations of various harmful gases;
•The instrument uses ultraviolet differential method measurement principle, low detection concentration, strong anti-interference ability, high measurement accuracy;
•Users can customize measurement parameters and ranges for gas components such as SO₂, NOₓ, O₂, CO, CO₂ according to actual needs;
•The instrument can automatically calculate emissions of harmful gases, fuel combustion efficiency, and excess coefficient;
•Compact overall structure, resistant to transportation, drop, and impact;
•Large-screen Chinese display, intuitive and simple operation;
•Built-in micro printer for direct data printing;
•Can store 3000 sets of measurement data, users can query through LCD screen, copy data to U disk via USB interface for saving, automatically generate EXCEL format, and can also print directly;
•The instrument has internal temperature compensation function, suitable for use in different temperature environments;
•Uses high-precision temperature sensor and imported pressure sensor to measure flue gas working conditions, accurate and reliable;
•Optional pitot tube can automatically measure static pressure, velocity, and temperature of flue gas in flue, or manually input flue gas velocity and temperature;
•Equipped with flue gas preprocessor to cool, dehumidify, and remove water from flue gas before entering analyzer for detection;
•The instrument can use AC/DC dual power supply. Power supply uses AC220V, or external DC24V as backup power.
