Clear Spring Scales

It isn't always convenient or practical to use an electronic scale. You may not have access to an outlet, you may be out of batteries, or you might be conducting experiments away from your lab. When an electronic scale isn't going to cut it, try our Clear Spring Scales. These Clear Spring Scales can measure up to 5000 grams (5kg) of mass or 50 Newtons of force and don't require an electricity source of any kind. These Clear Spring Scales are small enough to fit in your backpack (or even a fanny pack) and are constructed of durable plastic and metal parts.
