Sufficiently accurate, stable and consistent
on 18 December 2015
The Smart Weigh Digital Pro Pocket Scale with Back-lit LCD Display, Hold Feature and 2000 x 0.1g Capacity is a small portable scale designed either for measuring small items or small quantities of ingredients that are sometimes demanded by recipes; some may use fractions of a teaspoon or tablespoon but others may use metric weights so low that using a set of digital kitchen scales may be impractical - they often tend to be incapable of measuring less than 20-25g and can be inaccurate at weights slightly above.
This is to replace a broadly similar product purchased a few years ago and found so unreliable that the same item can produce vastly different successive readings each time that it is weighed, and they can vary within a range of a specific weight and another 15 or 20 times greater. Allowing the scales to acclimatise to room temperature, air movements etc which may conceivably affect it do not result in any improvement. Although absolute accuracy is not expected, consistency is as long as its readings are meaningful and within reason of each other. Accuracy is quoted as being as within 0.1g which is reasonable and respecatble, if not to laboratory standards which is not expected at this price level. There is no specifically quoted level of accuracy but it will read to within 0.1g and up to 2Kg.
The scales require a 1Kg calibration weight which is not included and not offered by Amazon. Consequently 2 x 500g weights from Smart Weigh have been ordered, although they are together more expensive than the scales themselves. There is a CAL setting to help set its readings in the event that they should become unreliable over time.
The scale is powered by 2 AAA batteries (carbon, not alkaline) which are not ideal and will be replaced ASAP for better reliability and their leak-resistance. There is two-piece hard acrylic case to help protect it when not in use, the larger section protecting most of it and the smaller section protecting the platform but either or both could double as a scale pan, the larger being the deeper and potentially more useful.
As with all such scales, there is a backlit LCD screen and four control buttons which control power and its various settings including scale of measurement with metric (g), Imperial (oz), troy ounces (ozt), pennyweight (dwt), grains (gn) and carats (ct) as its options. It is also possible to Hold a reading and to use Tare (deduct the weight of a small container from the weight of that container plus contents) and a PCS (pieces/quantity) button, the function of which is to provide a count of a randon number of an item once a weight had been established for a specified quantity (10, 20, 30 or 40).
The scales have several potential uses other than in cooking, include postal use, counting or weighing small components, weighing small amounts of scrap metal and especially precious metals, precious and semi-precious stones and also for those mixing photographic and other chemicals at home or in a laboratory as a substitute for an expensive high-grade balance.
The scales are quite substantial, if judging by weight alone, and just about pocketable although it would need to be a large pocket. It appaers to be able to provide accurate and repeatable readings without wandering unduly between wild extremes. It needs a second or two to settle but is essentially immediate. Accuracy, with or without calibration, appears to be excellent and also repeatable which provides dependability. If you need a digital scale to weigh small quantites of anything, this is candidate.
