I have used kitchen scales, zero the scale with the spring on the balance then press down on it about halfway or so. You need to make sure you are compressing the same amount and test some springs you know the rating of. Compress them until you get the same value as they are rated at. You can then compress the spring you don't know to that amount and read off the value.

There is quite a lot of science to doing it correctly but this is a pretty rough and ready way.
