Eisco Labs Acrylic Tubular Spring Scale (Dynamometer) 20N/2kg Capacity - Pull Scale, Force Meter

Easy to use, smooth travel

I've been working with some motorized projects lately, and needed some way to measure force in about this range. This scale is quite easy to use, not too hard to read, and easy to zero using the nut on the top, but it's pretty coarse in terms of the readings, with tickmarks every .4 Newton/40g. I did test it with a 100g (the largest calibrated mass I have) and it does seem to be accurate, at least at the low end. Overall, a useful if somewhat limited tool.

This worked fine and is of reasonable quality. Nothing fancy. But it will do the job.
