Humboldt provides testing sieves for soil sampling and classification, aggregates and granular materials sampling and ASTM standard tests. We keep an extensive offering of sizes and mesh/frame configurations in stock and ready to ship.
Humboldt's high quality, durable sieves comply with AASHTO M92 and ASTM E11 standards and optional certification is also available. Each sieve comes with its own serial number and the high quality manufacturing ensures accurate specifications and consistent fit.
Material configurations of Humboldt sieves include brass frame and mesh, brass frame with stainless mesh or stainless frame and mesh. The brass models are more economical while the stainless models have a longer life expectancy and mesh that resists sagging. To aid in stackability, our sieve frames are constructed with seamless spun brass or stainless steel with extended skirts and rigid rolled edges.
All Humboldt testing sieves display the sieve number, micron size and the nominal opening information on a permanent metal plate. Humboldt also provides a great inventory of sieve separator pans, covers and bottom pans.
