Minimize contamination concerns and are ideal for self - contained use in the lab or field
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
Oakton Traceable One - Shot conductivity and TDS standards include detailed KCl, NaCl, and 442 conversions, temperature corrections, and certified values referenced to 25° C
Average accuracy at 25° C is +/ - 0.25 microsiemens for 1, 5, 10 microsiemen (uS) solutions, or +/ - 0.25% for all other solutions. The tested uncertainty is shown on the certificate, whichever is greater
