Spring Scale,Blue 250g/2.5N

These spring scales provide direct readings for both force and measurement experiments. The transparent tube allows full view of the action of the spring. They are color coded for easy use, calibrated in both grams and Newtons and feature readings that range from 100 g/1 N to 5000 g/50 N. The fusion-welded tubes are durable and are great for force and measurement experiments. The scales are 10" long at rest, 13" long fully extended. Image may vary.
