Technical Overview

High-durability 0-300mm analog caliper featuring 0.05mm graduation, ±0.08mm accuracy, 14-degree vernier face angle, and four-way measurement capabilities.

Key Features

Measures outside diameter (OD), inside diameter (ID), depth, and steps
Small vernier face angle (14°) provides highly readable scales and minimizes parallax errors
Constructed of hardened stainless steel for outstanding durability and corrosion resistance
Satin-chrome finished main and vernier scales prevent glare and provide clear legibility
Equipped with a secure locking clamping screw atop the slider to hold jaw position
Smoothly raised sliding surfaces prevent wear and tear on graduation markings

Industrial Applications

1. Heavy Machining & Metal Fabrication Inspection

Perfect for measuring medium-to-large machined metal shafts, bored holes, and milled steps in heavy machining environments. The robust stainless steel build and lack of electronic components make it immune to oil, coolant splashes, and magnetic interference commonly found near CNC machines.

Problem Solved

Prevents failure or inaccurate readings caused by magnetic fields, cutting fluid ingress, or dust getting into electronic encoders, which frequently disable digital calipers.

2. Automotive Engine Component Tolerancing

Enables fast and reliable verification of automotive engine blocks, cylinder sleeve depths, and large valve guides up to 300 mm. Its blade-type depth bar allows quick step and depth verification of combustion chambers.

Problem Solved

Ensures engine components meet strict dimension tolerances during assembly or rebuilds, providing a mechanical failsafe reading that requires no batteries or calibration of electronic sensor loops.

3. Maintenance, Repair, and Operations (MRO) Field Inspection

Provides high-precision dimensional logging of pipe fittings, structural flange steps, and industrial pump shafts during field maintenance. Since it operates mechanically, it can be deployed instantly in harsh outdoor or hazardous explosion-proof areas.

Problem Solved

Eliminates downtime caused by battery depletion or electronic screens cracking/failing due to extreme temperature fluctuations in field environments.
