(1) - American Weigh Black Blade Digital Pocket Scale, 1000 by 0.1 G

Absolutely fantastic scale. Compact and light weight. In addition to the scale it comes with two plastic shells that cover your scale on the go and double as trays you can set on top, for liquids and small debris. It has several settings for weight and is consistent on its measurements. Really well made.

(Full specifications included below.) I chose this scale because I wanted an inexpensive, compact scale with a high capacity and at least 0.1g accuracy, and because the reviews looked good. I intend to use the scale mostly for weighing small bubble-wrap mailing envelopes and small shipping boxes, but I will sometimes need to weigh herbal supplements, and I need those weights to be accurate to a tenth of a gram or so. I was not sure if a scale with such a high capacity would be sensitive enough to measure small changes in weight, such as when I add a tenth of a gram of herbs to the weighing platform, so I also bought American Weigh's Chrome-201 (200g x 0.01g). With its help, I conducted some tests. This scale does sometimes report 0.1g changes in weight, but not reliably. It usually requires a 0.2g cumulative change to update the reading, unless I press on the scale or lift and replace the weight, which causes the reading to update and reflect the 0.1g change. The scale does reliably detect 0.2g changes in weight, even when that weight is added very gently and gradually. This is true whether the starting weight is near zero or near 1000g. The scale cannot detect a total weight of less than 0.2g (this is listed in the specifications). The work-around is to use a tray and zero-out its weight with the Tare feature. This scale has an "acceptable tolerance" of 0.2g, so that is probably the reason for these behaviors. I conducted my tests using powder (gently sprinkled), an eye dropper of water, and shreds of paper. I verified the readings with the Chrome-201. Both scales seem to be accurately calibrated, and usually gave matching readings (though they were sometimes off by 0.1g). The Chrome, by the way, exhibits the same behavior of updating the reading typically only when the weight has changed by at least 2 increments (0.02g in that case), and it only reliably detects a total weight of at least 0.05g. I have a few minor problems with this scale. See the CONS section below. AWS Blade-1kg Specifications: -------------------------------------------- Max Capacity: 1000g Min Weight: 0.2g Units: gram, ounce, troy ounce, pennyweight Acceptable Tolerance: 0.2g Calibration Weight: 500g (the manual and the scale itself reported this, and I successfully performed the calibration) Recommended Accuracy Class: OIML M2 Power: 2 x AAA (included - be sure to remove the plastic tab between the batteries and the contact) Dimensions: 0.8" x 3.8" x 3.8" Platform Dimensions: 2.7" x 2.7" Made in China PROS: ---------- Seems accurate, both by comparing to the CHROME-201 scale (readings usually match, or are sometimes off by 0.1g), and by weighing US coins. Readings are also reasonably consistent. The case and lid make good trays, and the case (being taller) can serve as a standoff for large items that would otherwise obscure the readout. Seems sturdy and the build quality seems good (for a cheap scale). CONS: ---------- The bottom tray/case fits so snugly that I can remove the scale from it only by holding the case and striking the heel of my hand sharply against a firm surface to knock the scale out of it into my other hand. I do not like doing that with something so delicate. The top tray/lid does not protect the weighing platform from pressure. It fits right against the platform and the scale will report weight when I press moderately firmly on the lid, even near its corners. And even though the lid fits within the bottom portion of the case, it sits higher than the top of the case and so even the case will not protect the scale from things being set on top of it. The swing-out unit would be better if it could swing out all the way so that it would be less easily obscured by large objects on the scale. When testing the scale's ability to detect tiny changes in weight, I found that the auto-off will activate even when there are small (0.1 - 0.2g) changes being reported in the readout at least every ten seconds. I assume this is because the scale has a tolerance of 0.2g, and so changes by no more than this do not count in the software as activity. I can prevent this by pressing on the scale periodically.

I use this small scale to weigh hops for brewing and it is perfect for that job.

El envio rapido y oportuno por parte de amazon Empaquetado igual de excelente forma. Funciona a la perfeccion, es de material muy bueno se nota al tacto y en cuanto al peso tambien. Precio en relacion a la calidad del producto pues de lo mejor excelente compra.

I purchased these scales in order to help me refill my Canon inkjet cartridges by weighing them when full in order to calculate exactly how much ink to add when they show as empty. I also thought they would be useful for my wife when she weighs small quantities of ingredients in her cooking. The scales are reasonably well made ,very compact, accurate and well priced. They are easy to calibrate and there is no need to buy a separate weight for testing purposes. I used the weights we already had for traditional kitchen balance scales but you could use almost any small item of a preknown weight(eg a coin). The degree of accuracy is excellent and more than adequate for domestic purposes - it was spot on for most of the kitchen weights. Occasionally it showed 0.1 gram difference but that could easily have been the test weight that was out. The tare facility is very useful so that the weight of the weighing receptacle is taken into account and zeros the display so that what then goes into it is the only thing that shows on the display.It is best suited to weigh small objects which will fit into the small weighing pan and whilst this one will weigh up to a kilogram I do not anticipate getting anywhere near that. Time will tell how durable it will turn out to be. I echo all the other positive reviews.
