LISTED UNDER:

Control Co.’s Traceable pH Standards and Certified Reference Materials are 100% compatible with all instruments and probes. Accuracy at 25 C is +0.010 pH, which is extremely precise. Control Co.’s Traceable pH Standards and Certified Reference Materials are 100% compatible with all instruments and probes. Accuracy at 25 C is +0.010 pH, which is extremely precise. The CRMs produce results that meet federal, state and local agencies’ strictest mandates and deliver exact calibration results for all pH meters. Certification is extremely accurate—A2LA  ISO 17025 and ISO Guide 34 provide highest achievable levels of quality assurance, product production, documentation and accuracy. ISO 9001 ensures world-class product standards are always met. Additional accreditations include ISO 31 for content and ISO 35 for statistical analysis. All CRMs are manufactured to IUPAC criteria. IUPAC features include resistance to temperature changes and long-term buffer stability during pH meter calibration. Each 16 oz bottle or 6-pack single-use 100 mL-container is supplied with an individual temperature compensation chart, traceability information, and Traceable Certificate. To assure accuracy, an individually serial-numbered Traceable Certificate is supplied to indicate traceability to standards provided by NIST and/or a National Standards Laboratory.
