Youpin ATuMan Duka ES1 Review Electronic Scales

Electronic scales ATuMan Duka ES1: checking accuracy with 1984 weights. Today’s review will be devoted to the new model of kitchen scales ATuMan DUKA ES1, this brand is part of Xiaomi Youpin ecosystem and this fact should be encouraging in terms of workmanship, as well as measurement accuracy. Measurement range from 0 to 3kg, accuracy within ± 2g. Additional buns include a built-in 450 mAh battery and a Type-C port for charging. To check the measurement accuracy, we will use the Soviet set of weights G-4-211.10 (produced in 1984).

Factory packaging in dark colors. The version of the scale is Chinese, so the presence of English on the box is minimal.

The appearance of the scales is rather laconic and is a black, thin rectangle divided into 2 parts: the scale platform and the display / control unit. The dimensions of the scales are 19 * 13 * 1.7cm.

Like the entire body, the scale plate is plastic and has diagonal lines that are likely to be clogged with food (if the scale is used for its direct kitchen purpose). At the same time, there is no degree of moisture protection, but everywhere there is a mention of “fully waterproof / washable case.” I will not experiment, but the lack of an indication of the IP degree is alarming.

The display / control unit is also made of plastic, the controls are touch-sensitive. The number of characters placed at a time is 5. The backlight is white, bright. There is an automatic shutdown after 180 seconds.
Let’s dwell on the management in more detail. The lower block allows you to perform mathematical functions of addition / subtraction, as well as to switch blocks in history. The upper block is represented by an on / off / zeroing button and a history button / changing the measurement system (g, ml, kg, oz, lb). The touch buttons have a good response, they work even with wet fingers. What did not like, very easily soiled surface.

For charging the scales, a typeC port is provided, covered with a dense plastic plug (if you look at the back of the plug, you can see the mold of the connector itself, which still prompts the idea of ​​moisture protection). The capacity of the built-in battery is 450 mAh, how long it will last is unclear. At the moment, the scales have been in operation for the third week and during this time they have not sat down. There is no discharge / charge indicator.

The reverse side is made of cheap plastic that loves to collect prints. There are rubber feet around the perimeter and in the center. Stability is lame due to the central leg, it is advisable to remove it.

In the upper part there is an eyelet for wall mounting of the scale. In the normal state, the eyelet is hidden deep into the body.

Brief characteristics at the bottom. For those who find the 3kg payload small, the ES1 8kg version in a similar case is provided.

To check the measurement accuracy, we will use the Soviet set of weights G-4-211.10 (produced in 1984). This set will allow you to understand how much the declared accuracy of ± 2 g corresponds to reality.

The tests were run from highest to lowest. Measurement of readings does not depend on the location of the weight on the site. So:

  • 100 – 100.3gr
  • 50 – 51.4gr
  • 20 – 21gr
  • 10 – 10.8gr
  • 5 – 5.7gr
  • 2 – 2.4g
  • 1 – 1.5gr

At the same time, the scales “play” on a central rubber penny, because of which the results obtained are constantly different. The first test was with more accurate readings, the repeated one on the camera already had a large error (for example, 2g – 2g, 20g – 20.2g).

We sum up all the “working” weights and we get – 189.3g, while the reference weight is 187g. At the same time, during the first test, the result was closer – 187.6g. The readings walk due to the unstable case on a flat surface.
Checking math calculations. To do this, we sum up the weights again and we get 191.3gr (the standard is 187gr). When subtracting, we get a weight of 1 g of a weight equal to -0.6 g. The accuracy is certainly amazing ..

Further tests were carried out in a more realistic, domestic environment. A pack of Barilla Tortiglioni pasta weighing 450g net, weighs 471.3g (forget that “net” is without containers and packaging). A pack of coffee with a net weight of 450 grams, weighs 460.6 grams.

A pack of Raffaello sweets with a net weight of 150g actually weighs 178.6g. If you believe the off. sources, then this pack contains 15 candies, 10 grams each.

In fact, the weight of one candy is ~ 10-11g (then we had to weigh each one to find out the total weight of 155g. In this case, a separate package weighs 24.6g. In total, we get 179.6g, which differs from the initial weighing by 1g.

Yogurt with a net weight of 500g actually weighs 530.4g.

In the end, it turns out that the ATuMan DUKA ES1 household electronic scales have an error that falls within the passport values ​​± 2 grams. In this case, the very accuracy of weighing depends on the level position of the scales, which do not have a stable position from the factory. Marking the surface of the block with controls also does not add a plus to the scales, and the lack of a standard battery charge indicator (should be in the lower right corner, if you believe the renders) generally raises many questions. In general, the scales work as a tool, but they need to be modified with a “file” (it is necessary to remove the rubber foot in the center).
