    500 G Calibration Weight
    Been a great tool to keep a recent purchase of a digital scale in check as I found out that the scale I bought even tho it was calibrated at the place of purchase it was off by .3 by the time I got it home I guess because of transporting it also if the scales not used for awhile it seems to always need recalibrating so this was a definite must have.

    calibration weight
    I didn't expect a lot here...but am actually surprised by how the quality of this piece shines through. Who expects something other than a simple weight. Haha well I can say its bringing me back next time.

    Handy item
    I ordered this calibration weight along with an order for a new scale. When I received the order, I checked the scale, and it was off just a tiny bit, so calibrated it using the weight. Worked just fine, and the scale is perfectly calibrated.

    glad I got it
    Even though the Jennings CJ600 scale says it comes calibrated I thought it would be a drag if I got it and it wasn't and I had to wait. Well my hunch was correct and the Scale was slightly off. I used the weight right away and it's been spot on since. Now I have it should I need it later.

    Looked all over the internet and could not find a 500g calibration weight anywhere that compared to the price and quality that Old Will Knott provided. Very fast service. I would recommend this company for all your weights. I looked at their scales for shipping and plan on ordering one from them later as well. Thanks Old Will Knott.
