Vernier Caliper with Self-lock

The caliper is fully constructed of polished rust-proof stainless steel, engraved with clear dual metric main and vernier scales. It is equipped with four measuring jaws: upper inner measuring jaws, lower outer measuring jaws, and a rear depth probe. A built-in thumb sliding trigger on the vernier block enables smooth one-hand sliding positioning, while a top locking screw fixes the slide to lock measurement readings.

Core Product Advantages

Pure mechanical structure requires no battery supply, eliminating power failure risks during outdoor field maintenance. The thumb trigger design greatly improves sliding operation convenience for single-hand measurement work.

Stainless steel body resists corrosion and abrasion in damp, greasy refrigeration workshop environments, with long service life and low failure rate. Standard 0.02mm measuring precision meets the dimensional inspection requirements of most HVAC spare parts.

Three-in-one measurement function integrates outer dimension, inner aperture and depth measurement, replacing three separate single-purpose measuring tools and reducing tool carrying load for technicians.

Applicable Scenarios

It is used for dimensional detection of refrigeration soft copper tubing, flaring tool dies, pipe bending molds, valve joints and metal hardware during air conditioner piping fabrication, refrigerator refrigeration system maintenance and spare parts incoming inspection.
