Accurate Indigo® 10,000 ppm quaternary ammonium (quat) test strips for verifying ultra-high sanitizer levels. Essential for invasive species control, industrial sanitation, & regulatory compliance.
Standard quat test strips only measure from 0 to 400 or 500 ppm, but certain applications require testing at far higher concentrations. Our 10,000 ppm quat test strips provide fast, reliable, and accurate measurement of quaternary ammonium compounds (QACs) at ultra-high sanitizer strengths. These test strips are essential for regulatory compliance in biosecurity, invasive species management, industrial-scale sanitation, and quarantine cleaning where maximum concentrations must be verified for safety and effectiveness.
All Indigo® Quat (QAC) test strips come in 100 (not 50) strips per pack & 3 year minimum guaranteed shelf life backed by a Certificate of Analysis, Stability & SDS documents as listed below; Certificate of Conformance on request. Be prepared for any health & safety audit or inspection.
Many agencies require proof that quaternary ammonium solutions are used at their prescribed strength. These test strips provide fast, defensible documentation that the correct concentration was achieved, supporting audits, inspections, and environmental protocols.
