Slimline table balance, weighs down to 0.1g and up to 3000g, can be switched to Troy ounces for weighing silver.

Suitable for weighing both gold and heavy silver items (3000g = 3Kg = about 96oz)

There IS an optional mains adaptor, should you wish to use this on mains power, though we find that the four AA batteries lasts so long, most people don't bother.

You need this specification but about half the size? See the NV-3000.

You need the highest capacity that you can get (but still readng down to 0.1g) with a pocket-size scale? notebk.

This is just the type of heavy duty table balance you need, perfect for the shop, but you need something that is approved (legal) for buying gold? See our standard gold balance, the Ohaus SJX1502M (3000g / 0.1g) or the FZ-200I-EC (200 / 0.01g)


This scale is guaranteed for 3 years (postage charged after 1 year, proof of purchase required after 2 years).

The guarantee excludes:

- flat batteries. New batteries will be charged at £5.00 plus £6.50 for return postage (UK).

- if you lose the battery compartment cover (sorry, we don't have spares)

The guarantee is invalid if there is:

- obvious damage, e.g. dents, holes, cracked casing, weighing platform loose.

- signs of 'foreign material'. That's anything that should not be there, e.g. residues of herbs, chemicals, spilt tea, corrosion from leaking batteries.


Inaccurate readings can usually be fixed by calibrating the scale, this is something you can do yourself if you have a 2Kg Calibration weight. THIS IS NOT A FAULT, all electronic measuring devices need calibrating every now and again, see calibrating weighing machines. We can calibrate it for you, for free, if it is returned within six months of purchase; after that, there is a charge of £5.00 + £6.50 postage (UK).
