Hach Company 1990 µS/cm Conductivity Standard; (995 mg/L TDS, 1000 mg/L NaCl), 1L
For calibrations/accuracy checks on conductivity meters.
Cole-Parmer Oakton Traceable Conductivity and TDS Standard, Batch-Tested, 100,000 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. Use when readings are expected to be around 100,000 S/cm.
Cole-Parmer Oakton Traceable One-Shot™ Conductivity and TDS Standard, 1000 µS; 6 x 100 mL Vials
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.
