With effective scale lengths of nearly 9″, Rotary scales offer greater accuracy than linear scales. All balances are graduated in gram/Newton. Dial: 3″ diameter metal suspension ring at top and hook at bottom.
Transparent plastic body. Each scale has been individually calibrated and equipped with a high grade spring with adjustable zero. High contrast marking make readings easy. Plated steel suspension ring at top and hook at bottom.
In the robust plastic transparent body, overall length 285 mm approx. with upper & lower suspension hooks, with zero adjustments, scales are both in grams and Newton.
Our color-coded spring scales provide direct readings for both force and measurement experiments. Each is calibrated in both grams & newtons. The transparent tube allows students to see the action of the spring. Ages 10+
