Whitehouse Sieve Standards No.170 (90 micrometer)

Whitehouse Sieve Standards No.170 (90 micrometer)

Whitehouse Sieve Standards offer a precise and efficient way to calibrate No.6 (3.35mm) and finer sieves, with full traceability to NIST. Calibration is simple, taking just minutes, without the need to ship your sieves away or put them out of service. Regular checks using these standards help identify when sieves need replacement. Each set includes five single-use vials of glass beads designed for one specific sieve size. For 8in or 200mm sieves, one vial is enough, while larger sieves up to 18in or 450mm may require two to five vials. Once processed, the average aperture can be quickly determined using the included calibration graph.

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

Whitehouse Sieve Standards for No. 170 (90µm) sieves come with five vials, each containing a nominal weight of 1.0g, ensuring accurate calibration and reliable performance testing.
