M838.715 measuring scale — Electronic rule with magnifier, carbon body (0–450 mm), Metav IndustryLine

The M838.715 measuring scale is an electronic workshop ruler with an integrated magnifier and proximity data output, designed for precise component measurement and straightforward digital transfer in production and inspection tasks.

• Electronic scale with integrated Ø41 mm magnifier
• Carbon construction for reduced weight and high stiffness
• Dual mm/inch display with Reset/Preset function
• Proximity data output for efficient data capture

Precision where mid-range measurements matter

The instrument belongs to the mid measurement class (300–500 mm), making it ideal for medium-sized components in fixture and mould construction. With a nominal measuring range of 0–450 mm, the design balances reach and rigidity: longer than compact rulers yet still manageable as a single-handed tool. The combination of 0.01 mm resolution and a stated accuracy of 0.03 mm allows reliable repeatability for workshop quality control, reducing rework and inspection time. This measurable performance supports faster decision-making on the shop floor and tighter process control.

Clear readout and digital-ready workflow

A clear digital display with mm/inch selection and Reset/Preset ease repetitive tasks and cross-team communication. The Proximity data output enables non-contact transfer to compatible data loggers or inspection software, streamlining documentation and traceability. Battery operation via 1× CR2023 keeps the instrument mobile; the compact power supply supports intermittent use without bulky cabling. These features make the device a practical bridge between manual measurement practice and digital record-keeping, improving throughput in small-batch and series production.

Designed for practical workshop handling

Constructed from carbon, the instrument combines low weight with sufficient stiffness for reproducible reading over its length; the overall length of 720 mm and a listed weight of 1 kg keep handling comfortable while preserving stability. The integrated Ø41 mm magnifier enhances readability of fine graduations and decimal values, reducing operator strain and speeding up routine checks. The robust interpretation of scales and tactile ergonomics minimise measurement variability, supporting consistent quality without complex training.

Suitability and application benefits

This measuring instrument is particularly suited to general machine and metalworking environments where medium-range precision is required: component mounting, sample checks, and inspection of intermediate assemblies. The mix of digital clarity, lightweight carbon construction and proximity output reduces cycle times and aids data capture for SPC or basic automation. For operations seeking to improve documentation and cut manual transcription errors, integration of this rule into existing workflows yields immediate efficiency gains and more reliable quality records.
