PartiStan particle standards are designed for calibration and verification of automatic particle counters.

Product History
In 1999, a new calibration procedure (ISO 11171) for automatic particle counters was introduced, rendering previous procedures (i.e. ISO 4402) obsolete. With the new procedure, primary calibration requires NIST SRM 2806-a suspension of 2.8 µg/L of ISO medium test dust in super-clean hydraulic fluid. This is available from Conostan as PartiStan 2806.

Conostan also offers a secondary standard for conducting verifications of working instruments or to calibrate more than one instrument in a laboratory. PartiStan secondary standards are compliant with ISO 11171 and prepared using SRM 2806.
