Antylia Control Company Oakton Traceable® Conductivity And TDS Standard, Batch-Tested, 150,000 Μs

Key Features

Oakton® Traceable® conductivity and TDS standards have detailed labels: KCl, NaCl, and 442 conversions, temperature corrections, and certified values referenced to 25°C—convenient. Average accuracy at 25°C is ±0.25 microsiemens for 1, 5, 10 microsiemen (µS) solutions, or ±0.25% for all other solutions or the tested uncertainty shown on the certificate, whichever is greater.

Batch-tested solutions are sampled and lot certified.

METHODS SUPPORTED
Certified reference material meets test requirements for Federal, State, and local agencies, CAP, ASTM, NCCLS, CLSI, ACS, CLIA, AOAC, EPA, APHA, AWWA, WEF, USGS, USP, and ISO. Traceable® Conductivity Standards complies with and is essential for use in these official methods: AOAC 973.40, EPA 120.1, Standard Method 2510 (APHA, AWWA, WEF), ISO 7888, DIN 38404, ASTM D1125, USGS I-1780, USP 645, and for A2LA/NVLAP accreditations/ISO 9000 certifications. Material may be used to calibrate all conductivity meters and to determine all conductivity cell constants.

A2LA ACCREDITATION ISO 17034 (1750.02)
To assure accuracy a Traceable® Certificate is supplied to indicate traceability to standards provided by NIST (National Institute of Standards and Technology) and/or a National Standards Laboratory. A2LA accredited certification provides the highest achievable level of quality assurance, documentation, and accuracy. Conductivity Standards are produced in an A2LA accredited ISO/IEC 17025: 2017 (1750.01) calibration laboratory and from an A2LA accredited ISO 17034 (1750.02) reference material producer. Additional certifications include ISO 31 (certificate content) and ISO 33405 (statistical analysis), plus ISO 9001 (certified quality manufacturer).
