TEST SIEVES 100mm/300mm/450mm
A Comprehensive Range of High Quality Test Sieves
Essa maintains substantial stocks of our own privately labelled test sieves in a range of common diameters: 100 mm, 300 mm and 450 mm.
Please click here to see our range of 200 mm diameter sieves.
These test sieves are manufactured to internationally recognised quality assurance standards. They are individually checked throughout manufacture either by optical projection or highly sophisticated computer scanning techniques and are certified for compliance with ISO 3310.
Each sieve is issued with a unique serial number and a certificate of compliance for full product traceability.
Essa specialises in sieves of stainless steel frame and mesh construction that are inherently more robust, durable and corrosion resistant than traditional brass sieves.
On the larger diameter sieves a reinforcing backing mesh is available for the finer aperture sieves. The 425 um backing mesh is supplied as an option for both 300 mm and 450 mm sieves with aperture sizes up to 212 um. These "B/MESH" sieves are listed in the model options below.
- Sturdy rim: strong and easy to handle
|
- Exact frame: rugged and uniform with positive nesting
|
- Fillet: no sample is trapped between the mesh and the frame
|
- Ergonomically designed: no raw edges and comfortable to handle
|
- Evenly tensioned mesh: precise and accurate results
|
- No cavities: totally sealed frame with no crevices to trap sample
|
- Precision mesh: high-tech optical equipment accurately measures apertures
|
- Fully traceable: individually numbered serial number
|
- High quality stainless steel frame: minimal corrosion and long lasting
