Whitehouse Sieve Standards No.120 (125 micrometer)

Whitehouse Sieve Standards No.120 (125 micrometer)

Whitehouse Sieve Standards offer a reliable and efficient method for calibrating No. 6 (3.35mm) and finer sieves, ensuring NIST traceability. Calibrations can be completed quickly, without the need to send sieves off-site, keeping them in service. Routine checks help determine when sieve replacements are needed. Each set includes five single-use vials of glass beads designed for a specific sieve size. For 8in or 200mm sieves, one vial is used, while larger sieves (up to 18in or 450mm) require two to five vials. Calibration results are easily interpreted using the provided calibration graph.

Recognized by the Community Bureau of Reference (BCR), Whitehouse produces standards for the European Community, with traceability to NIST, NPL, and BCR. The glass beads are crafted from 2.45 specific gravity soda-lime glass and certified for size using electroformed sieves, with additional verification through microscopy and image analysis.
