This spring force balance is made from sturdy acrylic, with a hanging eye and a load hook that extends from the scale head. Its design provides a reliable way to measure force by attaching weights to the hook. Capacity and setup - Two available ranges: 2.5 N (approximately 250 g) and 10 N (approximately 1 kg). - The measured force corresponds to the mass attached via the hook; attach the weight to the hook to determine the force. Intended use - Basic and secondary school science instruction as a teaching dynamometer. Practical applications - In classroom experiments, measure the pull of small masses to illustrate weight, force, and Newtons laws. - In lab activities, test simple pulley systems or string tensions by hanging weights and observing the resulting force. - As a durable, straightforward instrument for demonstrating fundamental force measurement concepts in a school setting.
