7-Button Digital Outside Micrometer

The micrometer features a reinforced cast iron C-frame with blue anti-slip coating on the outer surface, hard alloy measuring anvils, a locking lever, a ratchet pressure control tail, and an integrated LCD digital display module with multi-function operation buttons. Measuring range: 0–25mm, precision up to 0.001mm, supporting millimeter/inch unit switching, zero reset and data hold functions.

Core Product Advantages

Ultra-high precision of 0.001mm, far more accurate than vernier calipers and mechanical micrometers, suitable for detecting tiny dimensional deviations of thin-walled copper pipes and precision mold parts with strict tolerance requirements.

Direct digital LCD readout eliminates manual scale reading calculation errors; one-key zero calibration and unit conversion simplify on-site operation for technicians. The ratchet tail maintains consistent measuring pressure to avoid workpiece deformation from over-tightening.

Hybrid electronic-mechanical design combines digital readout convenience with stable mechanical spindle structure; alloy measuring contact faces resist abrasion, extending service life in long-term workshop use. The lock lever fixes the spindle to lock measurement readings for convenient recording.

Applicable Scenarios

It is used for ultra-precise outer diameter measurement of refrigeration soft copper tubing, miniature flaring mold inserts, valve spools, thin pipe fittings and tiny metal precision components during air conditioner piping production, refrigerator refrigeration system maintenance and high-standard incoming quality inspection of hardware accessories.
