Gold HEADGEAR VALUE IS HIGH, GRAM IS ABOUT HUNDREDS OF PIECES, MANY CONSUMER IS AFTER BUYING HEADGEAR, THE ELECTRONIC SCALE THAT COMES HOME CAN USE ONESELF HOUSEHOLD ANSWER WEIGHS, BUT LOOK, ERROR IS NOT SMALL HOWEVER. But actually, you know what? The scale, which jewelry calls gold, is quite different from the common electronic scale at home. Using an ordinary electronic scale to say gold, generally there will be a relatively large error.
Gold jewelry is a high-value product, a small deviation may lead to tens of hundreds of dollars of weight difference, so, for weighing gold scales must need to ensure two points: accuracy and sensitivity. Only when the weighing result is sufficiently sensitive and accurate can the weighing result be guaranteed 39bet-xsmb-xổ số tây ninh-xổ số binh phước-xổ số binh dương-xổ số đồng nai.
1, the special jewelry scale must be in a transparent sealing structure, so, the formal jewelry scale needs to be equipped with a wind shield, to avoid dust and air flow and other factors on the gold weighing results have an impact, and the general electronic scale is not sealed, the scale body is covered with dust, so the accuracy of gold jewelry weighing is greatly compromised;
2. Special jewelry scales will be equipped with high-precision electromagnetic sensors to ensure the accuracy of weighing results (generally above 0.01g), while general electronic scales are difficult to do this. The market is known as a common electronic scale that can accurately measure 0.01g, and the error is generally above 0.03g;
3, special jewelry scales can achieve fast and stable reading (generally seconds), at the same time, can achieve rapid calibration, overload protection, to ensure the accuracy and reliability of the weighing results.
In addition to the scale itself, the scale used for weighing gold needs to be checked every day. At the same time, it must be checked regularly once a year to ensure the accuracy of the weighing results in the long term.
That's why jewelry stores say gold scales are priced at a few thousand yuan to ensure maximum accuracy.
If the consumer IS WORRIED ABOUT GRAM WEIGHT, WHEN BUYING IN THE JEWELER SHOP, CAN LET THE CLERK ANSWER TO WEIGH TO YOU IN FRONT OF YOU, ACCORDING TO THE "METHOD OF SUPERVISION and ADMINISTRATION OF RETAIL GOODS WEIGHING and MEASURING" AS REVISED BY OUR COUNTRY IN 2004 RELEVANT REGULATION, TO BE LESS THAN or EQUAL TO 100 grams of GOLD, ALLOW TO EXIST ERROR OF plus or minus 0.01 grams, As long as it's within this margin of error, it's fine; additional, BUY GOLD JEWELRY SHOULD RECEIVE THE PROOF SUCH AS BILL, RECEIPT, IN CASE FOLLOW-UP TRUE DISCOVERY ERROR IS TOO BIG, THIS ALSO IS IMPORTANT PROOF.
