Vernier Caliper

The caliper is forged from polished stainless steel with dual-scale metric markings (main scale + vernier sub-scale). It is equipped with four measuring jaws: upper inner measuring jaws, lower outer measuring jaws, and a rear depth probe. A locking screw on the sliding vernier block fixes the slide position to retain measurement readings.

Core Product Advantages

Triple measurement functions (outer size, inner hole, depth) integrate three measuring tools into one, reducing equipment carried by field HVAC technicians. Clear engraved metric scales deliver stable precision with standard 0.02mm graduation accuracy.

Anti-rust stainless steel material resists corrosion from damp, greasy refrigeration workshop environments. Locking screw prevents slide shifting to avoid reading errors during data recording.

Applicable Scenarios

It is widely used for dimensional inspection of refrigeration copper tubing, flaring dies, bending molds and hardware fittings in air conditioner piping fabrication, refrigerator parts maintenance and mechanical tool calibration work.

Operation Guidelines

Outer diameter measurement: Clamp the workpiece between the lower outer jaws, tighten the lock screw, then read the combined value of main scale and vernier scale.

Inner hole measurement: Insert the upper inner jaws into the aperture, expand the jaws to fit the hole wall, lock and record data.
