Cole Parmer® Traceable® Conductivity Standards (CRM), 10 Micromhos, 0.1 Megohm Resistivity, 6.6 TDS/PPM, 16 oz. (500 mL) Bottle, 4065

Features:

• Certified Reference Material that is 100% compatible with all makes of instruments and probes
• Most accurate available —accuracy at 25 °C is (±0.25 microsiemens for 1, 5, 10 microsiemen solution or ±0.25% for other solutions) or the uncertainty shown on the certificate, whichever is greater
• Each bottle is labeled for calibrating conductivity (microsiemens/micromhos), resistivity (ohms), and dissolved solids (parts per million)
• Meets test requirements for Federal, State, and local agencies, CAP, ASTM, NCCLS, CLSI, ACS, CLIA, AOAC, EPA, APHA, AWWA, WEF, USGS, USP, and ISO and complies with and 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
• May be used to calibrate all conductivity meters and to determine all conductivity cell constants
• To assure accuracy, 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
• Double A2LA accredited certification provides highest achievable level of quality assurance, documentation, and accuracy
• Certified Reference Materials are produced in A2LA accredited ISO 17025 calibration laboratory by A2LA accredited ISO Guide 34 reference material producer
• Additional accreditations include ISO 31 (certificate content) and ISO 35 (statistical analysis), plus ISO 9001 (certified quality manufacturer)
• Each bottle is supplied with step-by-step calibration instructions, individual temperature compensation chart, traceability information, and Traceable® Certificate
