Colorful, inexpensive spring scales that provide direct readings for both force and mass measurements.
Each is calibrated in both grams and Newtons. The body tube is constructed of clear plastic with color-coded plastic ends, and chrome-plated hooks and rings. The top of each spring is leveled for easy use on an inclined plane.
Each scale can be fully zeroed.
