Ohm Meter Shunt Type Analog
Product Code : SCL-PLE-11851
The StemAids Shunt-Type Analog Ohm Meter is a specialized electrical instrument engineered for the empirical measurement of low-value resistances. Unlike series-type ohm meters, the shunt-type configuration is designed such that the unknown resistance is connected in parallel with the meter movement, making it highly accurate for measuring resistances in the range of 5Ω to 500Ω. Manufactured to ISO 9001:2015 standards, it is an essential tool for physics and electrical laboratories to quantify the resistance of coils, shunts, and short conductors.

Key Pedagogical Outcomes (Bloom’s Taxonomy Alignment)
- Meter Interface: Facilitates student understanding of current-division principles, supporting the study of Galvanometers and Meter Conversion.
- Low-Resistance Quantification: Enables the physical measurement of small resistances; learners apply the meter to conductors and observe how the shunt current affects the needle deflection.
- Scale Analysis: Supports the analysis of "Inverted Scales"; students evaluate why the shunt-type meter reads zero at the left of the scale, unlike the series-type meter which reads zero at full-scale deflection.
- Calibration Evaluation: Allows students to evaluate the impact of internal battery voltage on measurement accuracy, emphasizing the importance of the "Zero-Adjust" procedure before data collection.
International Logistics & Compliance
StemAids ensures comprehensive OEM readiness for global institutional procurement:
- Packaging: Export-grade seaworthy crating (ISPM-15 compliant). The instrument is secured with vibration-dampening foam to protect the delicate PMMC hairsprings and pivot-jewel assembly during transit.
- Documentation: Includes Manufacturer’s Authorization Form (MAF), Certificate of Conformance (CoC), and a technical guide explaining the mathematical derivation of the shunt-type scale.
- Durability: Tropicalized design featuring anti-tarnish terminals and moisture-resistant internal components, ensuring long-term scale accuracy in varying laboratory environments.
Direct OEM Sourcing Advantages
Procuring the StemAids Shunt-Type Analog Ohm Meter directly ensures vertical manufacturing control:
- Precision Movement Calibration: Every PMMC movement is individually balanced and calibrated to ensure a linear current response before being fitted with the non-linear resistance scale.
- High-Stability Internal Shunts: Direct oversight of component selection ensures that the internal reference resistors have a low temperature coefficient, preventing measurement drift.
- Direct Factory Spares Availability: Guaranteed availability of replacement meter movements, pointers, and "Zero-Adjust" knobs to maximize the long-term ROI of the laboratory assets.
- Safety Verification: Every unit is tested for insulation integrity, ensuring the metallic chassis (where applicable) is safely isolated from the internal measurement circuit.
