Spring Scales Stamp, Set 250g/2.5N
Spring Scales rubber stamps record both force and mass measurements. Stamps indicate calibrations in both Newton and gram measurements. Each stamp label is color coded to match the actual plastic scale color. All images are very detailed and accurately represented on finely crafted, hand finished wood that measures approximately 1 1/2" x 3". Visual and conceptual learning is reinforced as each stamped impression reproduces both the scale apparatus and number data of the device. Great for recording all activities.
