Mechanical Balance with Weights No Power Classroom Tray Balance Mechanical Laboratory Scale Tabletop Accurate for Teachers

A classic mechanical balance with weights designed specifically for hands-on physics education and classroom demonstrations. This two-pan scale allows students to measure mass and investigate fundamental density-related experiments with direct visual feedback. The tray balance features two shallow white pans, a central beam, a pointer, and a sturdy green base for stable tabletop placement. Equipped with a separate blue plastic weights box containing metal weights and tweezers, this beam balance offers everything needed for exact manual calibration. This battery-free mechanical balance helps students grasp the physical principles of mass and weight through tactile, interactive learning.
