About DIAVITE
DIAVITE AG, based in Bülach (Switzerland), develops and manufactures roughness measuring instruments, probes and accessories for tactile surface metrology. The product range includes the measuring instruments MICRO VH/VHF, DH-9/VH/VHF, DH-10 TOUCH, DH-8/App as well as NANO/VH/VHF, complemented by free-form probes, skid probes, drive units, measuring stands, calibration standards and custom probe solutions. The measuring systems use analog Hall-effect technology and diamond probe tips; all instruments are equipped with the ISO 21920 standard. The instruments are used in shop-floor and measuring-room applications and are distributed through a worldwide network of over 800 business partners. The company's history dates back to 1948; since 2016, a 400 m² large production and sales facility has been available at the Bülach site.
