Portable hardness tester for micro/macro Vickers and Knoop methods with indentation autoreading. Hardness testing on bulky tubes or valves in compliance with ASTM E384, ISO 6507 and ISO 4545 hardness standards. WIKI 30 is a motorized portable hardness tester targeted for use by the Oil & Gas market sector in order to control placed plants in loco. Automatic measurement system with autofocus and auto indentation readings. Swivelling turret (Indenter and objective) with 5 mm of horizontal stroke to perform multiple indentations without moving the tester. It is completely uninfluenced by direction so that it can operate up to 360° degrees of positioning, even upside down. It is not affected by any external source of vibration, and it does not need to be leveled. Load forces are electronically applied through a load cell which assures high accuracy in every condition long term. Micro-macro Vickers, Knoop and case depth tests, in laboratory or in loco, on all metals: iron, steel, tempered steel, cast iron, brass, aluminium, copper and metal alloys. Heat treatment, hardening, nitriding, cementation and hardfacing.
