The Kemio Check Standards kit provides a reliable method to verify the performance of Kemio Disinfection, Heavy Metals, and Kemio Multi meters. Each kit contains four precision electrical standards that simulate sensor signals, enabling an instrument integrity test in just 10 seconds. These standards are used to confirm correct meter function before or after testing routines, ensuring data quality and instrument reliability. Once verified, results are automatically logged for traceability. Recommended for regular quality assurance and audit readiness across water treatment, food safety, environmental monitoring, and industrial hygiene sectors.
