Standard Cole-Parmer 1413US

-Oakton Traceable One-Shot� conductivity and TDS standards include detailed 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 (�S) solutions, or �0.25% for all other solutions. The tested uncertainty is shown on the certificate, whichever is greater
-Conductivity options range from 1 to 200,000 �S/cm
-Batch-tested solutions are lot certified; a few bottles from a single lot are analyzed

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/IEC 17025:2005 (1750.01)
-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.�A2LA�accredited certification provides the highest achievable level of quality assurance, documentation, and accuracy.�Conductivity Standards are produced in an�A2LA�accredited�ISO/IEC 17025:2005 (1750.01)�calibration laboratory. Additional certifications include ISO 31 (certificate content) and ISO 35 (statistical analysis), plus ISO 9001 (certified quality manufacturer).
