Leclanche Cell Substitute
Product Code : SCL-PLE-11853
The JLab India Leclanche Cell Substitute is a high-stability electronic voltage reference engineered to provide a constant 1.5V DC output, replicating the standard Electromotive Force (EMF) of a traditional wet Leclanche cell. This solid-state alternative eliminates the maintenance, leakage, and corrosive chemical handling (ammonium chloride) associated with original carbon-zinc wet cells. It is an essential calibration tool for physics laboratories focusing on potentiometry and bridge circuits.

Key Pedagogical Outcomes (Bloom’s Taxonomy Alignment)
- Electrochemistry Interface: Facilitates student understanding of the standard EMF generated by carbon-manganese dioxide cells without the logistical challenges of wet chemistry.
- Potentiometric Quantification: Enables the physical calibration of laboratory potentiometers; learners apply the 1.5V as a secondary standard to compare against a primary Daniell cell (1.08V).
- EMF Measurement Analysis: Supports the analysis of "Balance Points"; students evaluate the ratio of lengths (L1/L2) on a potentiometer wire to determine the internal resistance of unknown sources.
- Source Stability Evaluation: Allows students to evaluate the difference between a regulated electronic source and a polarizing chemical cell, fostering a deeper understanding of internal resistance and terminal voltage.
International Logistics & Compliance
JLab India ensures comprehensive OEM readiness for global institutional procurement:
- Packaging: Export-grade seaworthy packaging (ISPM-15 compliant). The unit is housed in moisture-proof anti-static shielding to safeguard internal ICs during maritime or overland transit.
- Documentation: Includes Manufacturer’s Authorization Form (MAF), Certificate of Conformance (CoC), and a detailed laboratory procedure guide.
- Durability: Tropicalized design featuring coated PCBs to prevent oxidation in high-humidity climates, ensuring long-term voltage accuracy.
Direct OEM Sourcing Advantages
Procuring the JLab India Leclanche Cell Substitute directly ensures vertical manufacturing control:
- Precision Calibration: Each unit is factory-trimmed using a high-resolution multimeter to ensure the output is exactly 5V, mimicking a fresh chemical cell.
- Zero Maintenance: Eliminates the recurring costs of buying ammonium chloride and the environmental hazards of disposing of zinc and manganese byproducts.
- Direct Factory Spares Availability: Guaranteed availability of replacement battery clips, safety terminals, and internal reference ICs to maximize the long-term ROI.
- Operational Safety: Direct oversight of the internal current-limiting circuitry ensures the unit remains safe even if short-circuited by a student during experimentation.
