Noga DG3100 Articulated Arm Indicator Holder

Product Description

The NOGA DG3100 is an articulated arm indicator holder designed to position dial indicators, test indicators, and similar precision measurement instruments during inspection and machining setups. The arm spans 11.15 inches overall and features a knob-style adjustment mechanism along with a built-in fine adjustment function, allowing technicians to seat the indicator tip precisely without disturbing the broader setup. Constructed from aluminum, the DG3100 is lightweight without sacrificing rigidity. This holder ships without a base and is intended to mount to a weighted base or magnetic base sold separately.

The DG3100 is suited for use on machining centers, surface plates, lathes, and inspection fixtures wherever a repeatable, adjustable indicator position is required. The articulated arm design provides multi-axis reach, making it practical in tight setups where a rigid post arm would be too cumbersome. Metrology technicians, machinists, and QC inspectors working in job shops, tool rooms, and manufacturing environments are the typical end users of this holder.

Key Features

• Articulated arm design provides multi-axis positioning flexibility
• Knob adjustment with integrated fine adjustment function for precise indicator placement
• 11.15-inch overall arm length offers extended reach in tight setups
• Aluminum construction keeps weight low at 0.8 pounds
• M6 thread size at mounting interface
• 0.59-inch arm diameter with 16 mm clamping diameter for secure indicator grip

Compatibility

Designed as an OEM-style articulated indicator arm holder compatible with weighted and magnetic bases that accept an M6 threaded post connection. No base is included; a compatible base must be sourced separately.

Installation Notes

Installation is performed by machinists and metrology technicians without special tools beyond a compatible base. Secure the arm to the base post before attaching the indicator to avoid cross-threading the M6 connection. Confirm all knobs and clamps are fully tightened before zeroing the indicator to prevent drift during measurement. Do not exceed the clamping force recommended for the indicator collar being used.
