Verify strong acid strength during industrial cleaning and descaling with Indigo® pH 0–2.5 test strips. Fast screening without meters or calibration.
Industrial acid cleaning and descaling processes rely on highly acidic solutions to remove mineral scale, oxides, and process residues from equipment and surfaces. Indigo® Acid pH 0–2.5 test strips provide a fast, reliable way to verify that cleaning acids remain within the effective low-pH range during use. By delivering immediate visual confirmation of strong acidity, these strips help operators confirm chemical activity without exposing delicate pH probes to corrosive conditions, especially where accurate quantitative measurement are not required.
We've been selling pH test strips since 2005. All Indigo® pH test strips have Certificate of Analysis, Stability & SDS documents as listed below. They come 50 strips/pack with a guaranteed 3 year shelf life (dated back from expiration date "yyyy.mm.dd").
These strips function as a first-line verification tool, complementing meters and laboratory analysis where higher precision is required.
Warning: These acids are highly corrosive when concentrated. Wear safety goggles & shield, lab coat & apron, proper gloves & test in a fume hood if possible. Add acid to water not the other way around.
