Analog Frequency Meter
Product Code : SCL-PLE-11695
The StemAids Analog Frequency Meter (Vibrating Reed type) is a specialized electromechanical instrument engineered for the empirical study of AC circuit characteristics and mechanical resonance. Optimized for Secondary, Vocational (TVET), and Electrical Engineering curricula, this meter facilitates the quantification of alternating current frequency (f) through the principle of tuned physical resonance. Manufactured to ISO 9001:2015 standards, it provides a high-visibility, "no-parallax" display for verifying grid stability and generator output within institutional laboratory environments.

Key Pedagogical Outcomes (Bloom’s Taxonomy Alignment)
- Vibrating Reed Interface: Facilitates student visualization of mechanical resonance as a function of electrical frequency, supporting Electrical Engineering Module 101.
- Resonance Quantification: Enables the physical study of electromagnetic attraction, allowing learners to apply the concept of how a specific reed length matches the doubling of the supply frequency.
- AC Waveform Analysis: Supports the analysis of frequency stability in power systems, providing a real-time visual indicator of generator "hunting" or load fluctuations.
- Systemic Accuracy Evaluation: Allows students to evaluate the difference between digital sampling and physical resonance methods of frequency measurement.
International Logistics & Compliance
StemAids ensures comprehensive OEM readiness for global institutional procurement:
- Packaging: Export-grade seaworthy crating (ISPM-15 compliant) featuring specialized anti-vibration internal stabilization to protect the delicate reed alignment during transit.
- Documentation: Includes Manufacturer’s Authorization Form (MAF), Certificate of Conformance (CoC), and Technical Datasheets in English.
- Durability: Tropicalized design featuring moisture-proof coil insulation and corrosion-resistant reeds for reliable performance in varied climates.
Direct OEM Sourcing Advantages
Procuring the StemAids Analog Frequency Meter directly ensures vertical manufacturing control:
- In-House Reed Calibration: Reeds are batch-tested using precision frequency generators to ensure the peak amplitude occurs exactly at the marked frequency.
- Batch-Tested for Uniform Reliability: Every unit undergoes a high-voltage insulation test (Dielectric test) to ensure user safety during high-voltage AC demonstrations.
- Direct Factory Spares Availability: Guaranteed availability of replacement reed banks and electromagnetic coils to maximize long-term laboratory ROI.
- Manufacturing Control: Direct oversight of the metallurgical composition of the reeds ensures they maintain their "spring constant" and resonance accuracy over decades of use.
