Oakton 4562 Traceable® Conductivity Standard with Calibration, Individually-Tested; 200,000 µS, 16 oz, 473 mL

NIST-Traceable Calibration Standards are the most accurate available. Accuracy at 25°C is ±0.25 micromhos for 1, 5, and 10 microsiemen solutions and ±0.25% for other solutions or the uncertainty shown on the certificate, whichever is greater. Also includes step-by step calibration instructions and temperature-compensation chart. One 16-oz glass bottle.
Traceable® products are calibrated to NIST-traceable standards and ready to use as soon as you receive it. Each product goes through an intense vetting process before it can carry the Traceable name, and it includes NIST-traceable certification. This means that a 17025-accredited calibration test lab has confirmed that the product meets or exceeds all stated specifications, saving you both time and money by not having to calibrate separately.
NIST-traceable calibration also helps you meet quality standards and regulatory compliance for ISO, FDA, cGMP, VFC, CAP, CLIA and Joint Commission requirements.
