      Should I get this 20kg max gauge or this 50kg max gauge? Click here for a datasheet that covers both models.

      I think I only really need the 20kg one, but hey - the 50kg one is actually the same price! I'm thinking I might as well buy that one instead. Am I getting a better deal, or is there a disadvantage somehow? Both specs look absolutely identical. I would have thought that the 50kg one would have worse resolution, but the datasheet quotes 0.1N for both models.

      Am I missing something?

      The resolution is the same (0.1N) but the accuracy is 0.5% of full scale, so the 20kg one is accurate to 0.1kg but the 50kg one is only accurate to 0.25kg.

      Hi Peter - thanks for the reply. Oh I see now. I think I'll go for the 50kg. I can live with accuracy to 250g.

      I also had this response too from Farnell.
