Conductivity and TDS Standards
Cole-Parmer Oakton Traceable Conductivity and TDS Standard, Individually-Tested, 5 µS; 500 mL
All Oakton Traceable conductivity standards are NIST-traceable reference materials Supplied with a calibration report from an ISO 17034 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. Standards have detailed labels: KCl, NaCl, and 442 conversions, temperature corrections, and certified values referenced to 25C. Average accuracy at 25C 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.
Cole-Parmer Oakton Conductivity and TDS Standard, 111,900 µS; 5 x 60 mL Bottles/Pk
• KCl, NaCl and 442 conversions printed on the bottle for ease of use (excluded on 60-mL bottle, but included in insert) • Temperature corrections are printed on the bottle, with certified values listed in tables and referenced to 25°C (excluded on 60-mL bottle, but included in insert) • Manufactured under ISO 9000 quality guidelines and traceable to NIST standards • If unopened, shelf life is 1 year. If opened recommended shelf life is 4 months • Conductivity options range from 1 µS/cm to 200,000 µS/cm
