Premium Spring Balance, 0-500g / 0-5N - High Resolution, Dual Transparent Scale, Newtons & Grams - Zero Calibration Capability - Acrylic Body, Superior Quality & Finish - Eisco Labs

This spring balance has an acrylic body and reads 0 to 500g and 0 to 5N on a dual transparent scale with 10g subdivisions. It measures 9 inches long and 1.4 inches wide. Grams and newtons are printed on the same face, so a single reading gives both mass and weight and the fixed ratio between them is visible on the instrument. Zero point calibration is adjusted by pulling up or pushing down the tab at the top of the scale, which allows the balance to be zeroed before a measurement rather than corrected afterward. A loop at the top allows hanging from a stand or clamp, and a hook at the base holds the item being measured. The transparent body exposes the spring itself, so the extension under load is visible during use.
