The unique design of the Push/Pull Spring Balances means they not only weigh suspended objects but in addition using the extended rod, can also measure the force of pushing or pulling an object. They are colour coded, calibrated in grams and Newtons and have a clear flat area on the rod so you can, using a dry wipe marker, create your own scales. An instruction and ideas sheet is included. Beige, 1kg, 10N. While stocks last.
