LH1026 Ferrous Iron Test Strips, 2-10-25-50-100-250-500 mg/L (CAT#: STEM-AL-4062-ZJF)

LH1026 Ferrous Iron Test Strips is designed for rapid semi-quantitative screening of ferrous iron. A reactive pad develops a color after contact with the sample. The developed color is compared visually with the supplied reference scale. The graduated scale reports concentration as a defined range rather than a single instrumental reading. The compact strip format supports field checks and preliminary laboratory screening. The procedure requires only brief sample contact and a controlled color-development period. Dry sealed packaging protects the reactive area before use. The stated range and storage conditions should be followed for consistent results. The product supports routine screening within the documented concentration levels.
