Description
Atomfair Dust Free Silica Tester
Product Overview
Atomfair Dust Free Silica Tester is a professional testing equipment developed in accordance with international general standards, specifically designed for the production environment of electric power, coal, metallurgy and other industries, focusing on the accurate quantitative detection of free silica content in respirable dust. Adopting the principle of computer direct ratio recording and high-energy double blazed grating technology, the equipment avoids the drawbacks of traditional “pyrophosphoric acid gravimetric method” such as complex operation, long cycle and low precision, supports batch testing and multi-mode analysis, with easy operation and reliable data, providing professional support for dust hazard prevention and occupational health protection.
Core Functions
- Multi-Dimensional Data Processing: Support spectral baseline correction, data accumulation/smoothing/differentiation/four arithmetic operations and other functions, can complete %T & ABS conversion to ensure accurate analysis;
- Flexible Detection Modes: Cover three test modes (transmittance, absorbance, single beam) and three working methods (continuous scanning, repeated scanning, fixed-wavelength scanning) to adapt to different detection needs;
- Efficient Report Management: Support spectral peak detection, file management and scale/absorption expansion, can quickly generate standardized test reports, with convenient data storage and sharing;
- Stable Data Transmission: Equipped with USB interface, compatible with Windows system, the Chinese operation software reduces the difficulty of getting started, and data export is efficient.
