The Sulphite Test Strip is used to detect Sulphite ions in water-based solutions, measuring in increments of 10, 50, 100, 250, and 500ppm.
The Sulphite test strip will detect free sulphite. Detection of combined or total (free + combined) sulphite requires additional sample prep.
Various types of sulphites can be tested with this strip: sulphite, bisulfite, and metabisulfite. Our original colour chart was developed to measure sulphite ions in ppm (from sodium sulphite standards), however, we have checked standards and found that bisulfite and metabisulfite also match the same colour chart.
