The interchangeable rod depth micrometer is available as standard mechanical, mechanical digital and electronic digimatic (see separate digimatic entry). All models have hardened tool steel bases. Measuring rods are ground and micro-lapped on the faces. The sleeve and thimble are satin-chrome finished. Rod diameters are .157” (4mm) and are adjustable in either direction for calibration and wear compensation.

Accuracy: Rod diameter: 4mm.
Measuring length per rod: 1” (25mm).
Instrument error: ±3µm.
Flatness of reference face (bottom face of base):
1.3µm for 60mm/2.5” base. 2µm for 100mm/4” base.

The Mitutoyo® interchangeable rods provide flexible depth measurements over a wide range using interchangeable rods.   

Features and Benefits
• The robust tool steel bases provide a solid foundation, ensuring stability during measurements, preventing any unwanted shifts or inaccuracies
• Meticulously ground and micro-lapped measuring rods guarantee precise and reliable measurements every time
• The sleek satin-chrome finish on the sleeve and thimble not only adds a touch of elegance but also enhances durability, protecting against corrosion and wear
• Effortlessly customise your calibration with adjustable rod diameters (.157in. or 4mm), allowing you to adapt to various measurement needs and ensuring consistent accuracy over time
• The combination of durable construction and wear compensation in both directions significantly extends the lifespan of the measuring tool, providing long-lasting reliability for your projects

Notes
• Accuracy: Rod diameter: 4mm
• Measuring length per rod: 1" (25mm)
• Flatness of reference face (bottom face of base):
1.3µm for 60mm/2.5in. base
2µm for 100mm/4in. base
