MR66 Analog Panel Meter
Product Code : SCL-PLE-11811
The JLab India MR66 Analog Panel Meter is a professional-grade moving-coil instrument engineered for precise electrical monitoring in DC circuits. Featuring a standard rectangular profile (approx. 60×70mm), it offers a larger scale area than the MO65 series, providing enhanced readability for University-level physics experiments and industrial control panels. The MR66 is designed for high-fidelity tracking of current and voltage where visual trends and mechanical damping are critical for data interpretation.

Key Pedagogical Outcomes (Bloom’s Taxonomy Alignment)
- Dynamic Monitoring Interface: Facilitates student visualization of circuit transients and fluctuations, supporting the study of capacitor charging/discharging and inductive spikes.
- Parameter Quantification: Enables the physical measurement of electrical loads; learners apply these meters to verify the relationship between current (I) and voltage (V) in resistive networks.
- Calibration Analysis: Supports the analysis of measurement error; students use the front-facing zero-adjuster to evaluate the impact of mechanical offsets on experimental accuracy.
- Resolution Evaluation: The MR66's elongated scale allows students to evaluate smaller fractional changes in current compared to compact models, fostering higher precision in laboratory reports.
International Logistics & Compliance
JLab India ensures comprehensive OEM readiness for global institutional procurement:
- Packaging: Export-grade seaworthy crating (ISPM-15 compliant). Each meter is housed in individual anti-vibration shock-cells to protect the delicate sapphire jewel bearings and hairsprings from the stresses of transit.
- Documentation: Includes Manufacturer’s Authorization Form (MAF), Certificate of Conformance (CoC), and a factory-verified calibration report for the specific range ordered.
- Durability: Tropicalized design featuring anti-tarnish internal wiring and UV-resistant scale printing to prevent "yellowing" or fading in tropical or high-temperature laboratory environments.
Direct OEM Sourcing Advantages
Procuring the JLab India MR66 series directly ensures vertical manufacturing control:
- In-House Magnet Treatment: Every PMMC movement undergoes magnetic stabilization (aging) to ensure the flux density remains constant, preventing accuracy "drift" over the life of the instrument.
- Precision Hairspring Balancing: Direct oversight of the phosphor-bronze spring assembly ensures a linear torque-to-deflection ratio, resulting in uniform scale graduations.
- Direct Factory Spares Availability: Guaranteed availability of replacement clear-covers, mounting studs, and terminal nuts to maximize the long-term ROI of laboratory infrastructure.
- Manufacturing Control: Direct oversight of the scale-marking process ensures high-contrast, permanent ink application that remains legible under varying laboratory lighting conditions.
