Product overview
The DIGIMICRO series is a contact-type digital length measuring system using a built-in photoelectric linear scale. It enables thickness, depth and step-height measurement with high selectable resolution and a modular set of plunger heads, counters and stands to adapt to laboratory and production inspection tasks.

Models & Counters

• MF-1001 digital plunger head — 0–100 mm measuring range
• MF-501 digital plunger head — 0–50 mm measuring range
• MH-15M digital plunger head — 0–15 mm measuring range
• Counters: MFC-200 (minimum readable value 0.1 µm, switchable settings) and TC-200 (minimum readable value 0.01 µm, configurable scales)

Key highlights

• Selectable display resolution down to 0.01 µm depending on counter and settings
• Accuracy specified at 20 °C varies by model and counter (see technical specifications)
• High response speed up to 500 mm/s for MF-1001/MF-501; MH-15M limited to 100 mm/s
• Integrated high-precision Nikon linear encoder and protective anti-dust bellows on the probe shaft

Accessories

• Probe tip options: standard, pin, plastic, off-centre, flat and roller (6 types)
• Bench stands: MS-12C, MS-22S, MS-32G, MS-51C and MS-41G
• Optional accessories: LED illumination unit, calibration mirrors, carrying case, AC adapter or battery power options

Applications

• Contact measurement of thickness, depth and step height in laboratory and production quality control
• Precision inspection of small mechanical parts, electronic components and assembly processes
