MR87 Analog Panel Meter
Product Code : SCL-PLE-11810
The JLab India MR87 Analog Panel Meter is a professional-grade moving-coil instrument engineered for high-precision monitoring in institutional laboratories, industrial control consoles, and complex electrical test benches. With a larger form factor (approx. 80×100mm) than the MO65 series, the MR87 provides an extended scale length for superior resolution and easier reading from a distance. It is the preferred choice for applications requiring fine-tuned accuracy and high-fidelity tracking of DC current and voltage.

Key Pedagogical Outcomes (Bloom’s Taxonomy Alignment)
- High-Resolution Interface: Facilitates student understanding of fine increments and measurement uncertainty, supporting Advanced Electromagnetism and Metrology modules.
- Sensitivity Quantification: Enables the physical study of electrical characteristics; learners apply the meter to measure ultra-low currents (μA) or high voltages, observing the impact of internal resistance (Rm) on circuit loading.
- Complex Circuit Analysis: Supports the analysis of the "Null-Point" in high-sensitivity bridges; the wide scale allows students to evaluate the approach to zero with greater confidence than smaller meters.
- Instrument Error Evaluation: Allows students to evaluate and mitigate "Parallax Error" using the integrated mirror strip—a critical skill in professional engineering and laboratory data acquisition.
International Logistics & Compliance
JLab India ensures comprehensive OEM readiness for global institutional procurement:
- Packaging: Export-grade seaworthy crating (ISPM-15 compliant). Each unit is encased in anti-static, shock-absorbent molding to protect the precision-balanced pointer and delicate hairsprings from the rigors of maritime transit.
- Documentation: Includes Manufacturer’s Authorization Form (MAF), Certificate of Conformance (CoC), and a factory-verified calibration certificate for each unit.
- Durability: Tropicalized design featuring anti-tarnish internal components and UV-stabilized scale printing to prevent fading or mechanical degradation in high-temperature or high-humidity climates.
Direct OEM Sourcing Advantages
Procuring the JLab India MR87 series directly ensures vertical manufacturing control:
- In-House Mirror Calibration: Every scale is aligned with a precision mirror strip to ensure absolute linearity across the entire 90? deflection arc.
- Jewel-Bearing Precision: Direct oversight of the assembly ensures ultra-low friction in the pivot mechanism, providing the high sensitivity required for ±1.5% accuracy class standards.
- Direct Factory Spares Availability: Guaranteed availability of replacement clear-covers, zero-adjustment kits, and mounting hardware to maximize the long-term ROI of laboratory infrastructure.
- Manufacturing Control: Direct oversight of the magnetic stabilization process ensures that the permanent magnet maintains constant flux density, preventing accuracy drift over the lifespan of the instrument.
