The Aristo part compass with a round head made of solid metal is equipped with an extension rod and a universal adapter, and has been impressing technicians as a professional precision compass worldwide for decades. The fine spindle, which allows for mass adjustment using the central wheel, guarantees the highest accuracy. Even when retracting the compass, the set measurement remains unchanged. Each of the two legs is equipped with a joint. One leg offers the option to hold inserts with a diameter of 4.0 mm, for example, for an extension rod or for adapters for drawing with pigment pens or ink fillers. Non-slip clamps for the needle and the lead are standard with Aristo. The Aristo part compass is delivered together with an extension rod for circles up to a maximum diameter of 500 mm, a universal adapter, and a box containing 2 replacement leads in a transparent case.
