Description

This H-R series rechargeable digital caliper is an upgraded eco-friendly precision measuring tool designed for daily industrial and workshop use. Its built-in rechargeable battery system eliminates the hassle and recurring cost of disposable button battery replacement, while IP54 ingress protection ensures reliable performance in coolant-exposed, dusty and oily production environments. Combining premium stainless steel construction, tactile metal buttons and an extra-large readable display, it delivers both long-term durability and effortless operation for machinists, inspectors and hobbyists.

Built-In Rechargeable Battery with USB Charging

Equipped with an integrated rechargeable lithium battery charged via standard USB interface, removing the need for frequent SR44 battery purchases and replacement. A single full charge supports extended daily use, reducing long-term operating cost and disposable battery waste. The intelligent auto power-off function further extends battery runtime by automatically entering sleep mode after idle periods.
IP54 Certified Dust & Splash Protection

Officially rated IP54 for ingress protection, it resists harmful dust ingress and splashing water, coolant and lubricant from all directions. Sealed internal electronics and grating system withstand daily exposure to workshop fluids and metal debris, avoiding common liquid-damage failures of standard entry-level digital Calipers .
Extra-Large LCD Display & Durable Metal Buttons

Features an upgraded extra-wide full-screen LCD that delivers sharp, high-contrast readings, clearly visible even under bright overhead workshop lighting. All control buttons are made of solid metal, providing crisp tactile feedback and far longer service life than plastic buttons, standing up to thousands of daily operations in heavy use scenarios.
High-Precision Measuring System

Powered by an advanced capacitive grating sensor with 0.01mm / 0.0005" resolution, delivering stable and repeatable measurement accuracy. One-key instant switching between metric and imperial units adapts to international drawing standards and global working environments. Any-position zero setting supports flexible relative measurement and differential comparison for efficient batch inspection.
Industrial-Grade Stainless Steel Build

The caliper body and measuring jaws are precision machined from hardened stainless steel with anti-corrosion finish, offering excellent wear resistance and structural rigidity. Precision ground jaws maintain perfect parallelism across the full measuring stroke, ensuring consistent, trustworthy readings through years of daily industrial use.
4-in-1 Versatile Measurement Functions

One tool covers four common dimensional inspection tasks: outside diameter (OD), inside diameter (ID), depth and step dimensions, meeting most daily measurement needs in machining, assembly and quality control workflows. The smooth knurled thumb roller enables precise one-handed jaw adjustment, while the locking screw holds position firmly for off-part reading and data recording.
