Model BK-AA180B
Introduction:
BK-AA180B features an 8-lamp turret design, a flame atomizer, 6-level spectral bandwidth adjustment, and deuterium lamp background correction. It is suitable for the detection of over 30 flame-analysis elements, with a quantitative concentration reaching the mg/L (10⁻⁶) level and a detection concentration as low as μg/L (10⁻⁹). It is widely used in industries such as geology and mining, metallurgy, materials science, agriculture, forestry, soil and fertilizer, petroleum and chemical engineering, as well as third-party testing.

Features:
1. The instrument features a 20mm thick cast aluminum integrated optical platform with a suspended design, delivering exceptional stability of better than 0.002Abs/30min.
2. The flame atomizer system utilizes aerospace-grade polyphenylene sulfide (PPS) material with a molded one-piece construction, offering exceptional flame resistance, corrosion resistance, and high-temperature durability for extended service life.
3. The industrial-grade TA2 pure titanium burner, precision-finished with slow wire-cutting technology, provides excellent corrosion resistance and supports interchangeable wide-slit designs for high-salt sample analysis.
4. The next-generation flame control system integrates continuously adjustable gas flow, real-time status indicators, dual safety interlocks, and automatic ignition for reliable operation in demanding environments.
5. The optional oxygen-enriched flame upgrade achieves temperatures exceeding 2700°C without nitrous oxide, enabling precise determination of high-temperature elements like Ca, Al, Ba, Mo, Ti, and V.
6. Network port communication mode, offering significantly improved stability and data transfer rates compared to legacy interfaces like RS-232 and RS-485.
