Digital Vernier Caliper
Product Code : SCL-PLE-11774
The StemAids Digital Vernier Caliper is a high-resolution linear measurement instrument engineered for the empirical study of metrology and structural dimensions. Optimized for Secondary, University, and TVET (Technical and Vocational Education) laboratories, this digital interface eliminates human estimation errors associated with mechanical scales. Manufactured to ISO 9001:2015 standards, it provides a direct-reading LCD output for quantifying internal, external, and depth dimensions with superior repeatability.

Key Pedagogical Outcomes (Bloom’s Taxonomy Alignment)
- Metrology Interface: Facilitates student visualization of high-precision dimensions, supporting Engineering and Physics Module 101 by providing an intuitive digital readout of physical space.
- Dimensional Quantification: Enables the physical study of volume and density, allowing learners to apply the "Zero" function to perform differential measurements (e.g., measuring the thickness of a coating or wall).
- Error Analysis: Supports the analysis of "least count" and measurement uncertainty; students can compare the precision of digital readouts against traditional analog Vernier scales.
- Versatility Evaluation: Allows students to evaluate four types of measurement:
- Outside: Diameter of cylinders/thickness of blocks.
- Inside: Bore diameters of pipes.
- Depth: Deep cavities and holes.
- Step: Distance between two parallel planes on a workpiece.
International Logistics & Compliance
StemAids ensures comprehensive OEM readiness for global institutional procurement:
- Packaging: Export-grade seaworthy crating (ISPM-15 compliant) featuring a high-impact polymer protective case with fitted foam inserts to maintain calibration during transit.
- Documentation: Includes Manufacturer’s Authorization Form (MAF), Certificate of Conformance (CoC), and a Calibration Certificate traceable to international standards.
- Shelf Stability: Tropicalized design featuring battery-saver "Auto-Off" circuitry and moisture-resistant sensors to prevent digital drift in high-humidity laboratory environments.
Direct OEM Sourcing Advantages
Procuring the StemAids Digital Vernier Caliper directly ensures vertical manufacturing control:
- In-House Lapping Process: Measuring jaws are precision-lapped to ensure perfectly parallel faces, critical for maintaining accuracy at the 01mm level.
- Batch-Tested for Uniform Reliability: Every unit is tested against Grade-0 Gauge Blocks throughout its entire length to ensure linearity and zero-return accuracy.
- Direct Factory Spares Availability: Guaranteed availability of replacement batteries (SR44/LR44), battery covers, and specialized data-output cables for PC logging.
- Manufacturing Control: Direct oversight of the stainless steel hardening process ensures the "Beam" and "Jaws" resist wear and thermal expansion, maintaining calibration across years of student use.
