The Oakton Traceable Conductivity and TDS Standard, Individually-Tested, 200,000 µS, 500 mL is a high-range calibration solution designed for accurate, NIST-traceable conductivity measurements. Each bottle is individually tested to ensure unmatched precision, making it essential for critical lab and industrial calibration tasks.
Product Features
- Individually-tested to ensure 200,000 µS accuracy
- NIST traceable for regulatory compliance and reliability
- 500 mL (16 oz) bottle for laboratory and field use
- Supports high-range calibration of conductivity meters
- Ideal for industrial quality control and lab calibration
- Traceable conductivity standards are Certified Reference Materials, making them some of the most accurate available
- All Oakton Traceable conductivity standards are NIST-traceable reference materials
- Supplied with a calibration report from an ISO Guide 34 and ISO 17025 accredited laboratory
- These standard solutions let you calibrate conductivity instruments to ensure accuracy
- If unopened, shelf life is one year; once opened, shelf life will vary by solution value
- Use when readings are expected to be around 200,000 µS/cm
- 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 µS 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 µS/cm
- Individually-tested solutions are certified by the bottle—each bottle is analyzed for the best accuracy
- 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 comply with and are essential for use in 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 determine all conductivity cell constants
- Individually serial-numbered Traceable Certificate supplied to indicate traceability to standards provided by NIST 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
