Description
Condition: This Mitutoyo 513-444 test indicator is used and shows signs of sun fade or discolouration around the dial face (likely from sun exposure or possibly coolant). Despite the cosmetic wear, it remains fully functional, with smooth movement and reliable repeatability. It has anti-magnetic properties, which makes it well suited for use near magnetic fields or in environments prone to interference.
The 513-444 is a horizontal-type dial test indicator in Mitutoyo’s Series 513 line. It is engineered for high durability, sensitivity, and readability in shop and inspection settings. Its O-ring sealed bezel and bonded crystal design help resist penetration by coolant, dust, and oil, enhancing longevity. With a 0.01 mm graduation and compact lever style, it is ideal for comparative and alignment tasks in tight or obstructed setups.
