Analog Voltmeter Panel Type 500V AC DC
Product Code : SCL-PLE-11707
The StemAids Analog Voltmeter (500V AC/DC) is a precision-engineered moving-iron laboratory instrument designed for the empirical study of high-potential electrical systems. Optimized for Secondary, Vocational (TVET), and Electrical Engineering curricula, this panel-mounted meter facilitates the quantification of both alternating and direct voltage up to 500V. Manufactured to ISO 9001:2015 standards, it provides a high-impedance, "no-latency" visual indicator for verifying grid potential and power supply regulation in institutional laboratories.

Key Pedagogical Outcomes (Bloom’s Taxonomy Alignment)
- Moving-Iron Potential Interface: Facilitates student visualization of electromagnetic torque generated by voltage potential, supporting Electrical Engineering Module 101.
- RMS Voltage Quantification: Enables the physical study of AC power, allowing learners to apply the meter to measure effective line voltage across inductive and resistive loads.
- Potential Divider Analysis: Supports the analysis of voltage drops in series circuits, providing immediate feedback on the relationship between resistance and potential difference.
- Over-Voltage Sensitivity Evaluation: Allows students to evaluate the nonlinear "cramped" scale at the lower end versus the expanded upper-scale resolution typical of moving-iron instruments.
International Logistics & Compliance
StemAids ensures comprehensive OEM readiness for global institutional procurement:
- Packaging: Export-grade seaworthy crating (ISPM-15 compliant) featuring anti-vibration internal stabilization to protect the delicate pivot-and-jewel movement from high-G impact.
- Documentation: Includes Manufacturer’s Authorization Form (MAF), Certificate of Conformance (CoC), and illustrated Technical Manuals in English.
- Durability: Tropicalized design featuring high-dielectric coil insulation and moisture-sealed terminal blocks for reliable performance in varied climates.
Direct OEM Sourcing Advantages
Procuring the StemAids Analog Voltmeter (500V) directly ensures vertical manufacturing control:
- In-House Precision Calibration: Every meter is batch-tested against a certified high-voltage reference to ensure linear accuracy across the 500V range.
- Batch-Tested for Uniform Reliability: Every unit undergoes a 2kV insulation breakdown test to ensure user safety during high-voltage AC demonstrations.
- Direct Factory Spares Availability: Guaranteed availability of replacement mounting clamps, terminal nuts, and external multipliers to maximize long-term laboratory ROI.
- Manufacturing Control: Direct oversight of the hairspring tension and vane alignment ensures consistent damping and zero-point stability across all production lots.
