Kater's Reversible Pendulum
Product Code : SCL-MH-11940
Kater’s Reversible Pendulum is a laboratory-grade geodetic instrument engineered for the empirical determination of local gravitational acceleration with sub-millimeter precision.2 Designed for University and Graduate-level physics curricula, it satisfies rigorous ISO-compliant experimental protocols. This Educational Instrument resolves the inherent inaccuracies of simple pendulums by utilizing the principle of conjugate centers of oscillation and suspension.

Key Pedagogical Outcomes (Bloom’s Taxonomy)
Feature: Opposing Adjustable Knife Edges. Outcome: Allows students to Analyze the period of oscillation from two points, facilitating the elimination of the moment of inertia variable in calculations.
Feature: Bi-Metallic/Dual-Density Sliding Masses. Outcome: Enables the Evaluation of small time-period differences through center-of-mass shift, supporting Advanced Mechanics Module 202.
Feature: Rigid Geometry Construction. Outcome: Supports the Application of Bessel’s formula, allowing students to verify gravitational data independent of the bar's internal mass distribution.
International Logistics & Compliance
To ensure the geometric linearity of the pendulum bar and the microscopic integrity of the knife edges during intermodal transit, this Educational Instrument is secured in export-grade seaworthy crating (ISPM-15 compliant). Every consignment for international procurement includes the Manufacturer’s Authorization Form (MAF), IQ/OQ/PQ Certification, and technical User Manuals in English. The Tropicalized design is validated for operational stability in environments reaching 45°C and 90% Humidity, ensuring the high-carbon steel components remain resistant to atmospheric oxidation and thermal expansion skewing.
Why Source from the OEM?
Procuring from the Educational Instrument OEM ensures total vertical integration, from the in-house precision grinding of the knife edges to the metallurgical verification of the pendulum bar. Unlike third-party traders, our facility utilizes batch-tested for uniformity protocols, ensuring that the distance between suspension points is calibrated to laboratory tolerances. Sourcing directly guarantees direct factory spares availability—including replacement knife edges and calibrated sliding masses—providing a validated maintenance path for international TVET development tenders and government educational supply chains.
