This set of spring scales includes 6 high quality, dual unit tubular scales that can measure six different ranges of force (in Newtons) or weight (in grams). This multi range set of scales allows you to get higher precision results in either units.
Color Coded Scales included in this set are:
|Blue:||0 N to 2.5 N||0 Grams to 250 grams|
|Green:||0 N to 5 N||0 Grams to 500 Grams|
|Brown:||0 N to 10 N||0 Grams to 1000 Grams|
|Red:||0 N to 20 N||0 Grams to 2000 Grams|
|White:||0 N to 30 N||0 Grams to 3000 Grams|
|Yellow:||0 N to 50 N||0 Grams to 5000 Grams|
Newton units are used when you want to measure a force. Grams are used when you are measuring a weight.
