Control Company’s new Traceable® pH Standards Certified Reference Materials are 100 percent compatible with all instruments and probes. Features include:

Accuracy at 25° C is ±0.010 pH.
Materials have met Federal/State/local agencies’ strictest mandates.
They deliver exact calibration results for any pH meter.
A2LA ISO 17025 (Calibration Laboratory) and ISO Guide 34 (Certified Reference Material Producer) provide highest achievable levels of product production, documentation, and accuracy.
Additional accreditations include ISO 31 (content), ISO 35 (statistical analysis) and ISO 9001.
Select values are manufactured to IUPAC (International Union of Pure and Applied Chemistry) formulation.
All Certified Reference Materials feature resistance to temperature changes and long-term buffer stability.
Each 100 ml container is supplied with an individual temperature compensation chart and traceability information.
To assure accuracy, an individually serial-numbered Traceable® Certificate is supplied to indicate traceability to standards provided by NIST (National Institute of Standards and Technology) and/or a National Standards Laboratory.
