100g / 0.01g, model TUFF-WEIGH

Summary

Tough pocket scale with folding lid, suitable for weighing gemstones and small amounts of gold

Do you find that scales don't seem to last long? This one has a heavy-duty folding lid, this is the one to choose if you keep crushing your scales in your pocket (or between heavy items of stock); this does not mean it's indestructible, you can still destroy it by dropping it or getting it wet - but being able to carry it around without crushing it is a good start.

Technical Specification

RESOLUTION / CAPACITY: 0.01g / 100g (100g is about 3oz)

Also switchable to ounces (oz), Troy ounces (ozT), pennyweight (dwt), carat (ct) and grains (gn).

- Troy ounce (ozT) for gold and silver (and was once used for letters and parcels)

- grams, metric. Today everyone weighs gold in grams. But dealers tend to weigh silver in Troy ounces.

- ounce (manufacturers call it, "English Ounce", correct term is Ounce Avoirdupois) for food

- Pennyweight (dwt), pre-decimal system, still used in USA

- Carat (ct) for gemstones and diamonds, not to be confused with carat as gold purity). Carats are metric: 5 carat = 1 gram, 100 points = 1 carat.

- Grains, originally used for weighing gold (based on a grain of wheat), today used for weighing powder for ammunition or catalysts

Guarantee

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.

CALIBRATION

Inaccurate readings can usually be fixed by calibrating the scale, this is something you can do yourself if you have a 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 three months of purchase; after that, there is a charge of £5.00 + £6.50 postage (UK).
