Customer Questions & Answers

Question:
What is the ET18 RS Electronic Gold Tester used for?
Answer: The ET18 RS Electronic Gold Tester is designed to accurately assess the purity of gold items. It uses advanced electronic technology to provide precise readings of gold karats, making it an essential tool for jewelers, pawnbrokers, and collectors. By applying a testing solution to the gold surface, the device gives a digital readout of the karat value, ensuring that users can confidently verify the quality of their gold. This is particularly useful in scenarios where authenticity is crucial, such as during selling or appraising gold jewelry. -
Question:
How does the ET18 RS tester work?
Answer: The ET18 RS tester operates through a non-destructive testing method that involves applying a specially designed acid to the gold item. When the acid contacts the gold, the tester assesses the reaction and produces a digital output indicating the karat level. This system eliminates the need for physical scraping or damaging the item. Its ease of use makes it suitable for quick evaluations in various settings, including retail stores or home use, allowing users to verify gold purity without extensive training. -
Question:

Jewelers often rely on this tool to ensure that the products they offer meet quality standards, providing peace of mind to both sellers and customers in the jewelry market. -
Question:
Can the ET18 RS test other metals besides gold?
Answer: The ET18 RS primarily focuses on gold testing, but it can also provide readings for other related precious metals like platinum and silver, depending on the specific model specifications. However, its main functionality is geared towards gold purity. Users in the jewelry industry often use it to confirm metal authenticity before purchase or appraisals, ensuring they are dealing with legitimate materials, thus expanding its utility beyond just gold. -
Question:
What are the display features of the ET18 RS?
Answer: The ET18 RS is equipped with a clear digital display that showcases the karat results in an easy-to-read format. It generally features backlighting for visibility in low light conditions, enhancing usability in various environments. This user-friendly display allows for quick interpretation of test results, making it ideal for quick assessments in jewelry stores or trade shows where immediate feedback is essential. -
Question:
How accurate is the ET18 RS Electronic Gold Tester?
Answer: The ET18 RS is known for its high accuracy, typically providing readings with a minimal margin of error. Its electronic testing method eliminates many variables that can lead to inaccuracies in traditional acid testing. For jewelers and collectors, this precision is critical, particularly when distinguishing between similar karats or verifying authenticity immediately before a purchase or sale. -
Question:
What accessories come with the ET18 RS Electronic Gold Tester?
Answer: Typically, the ET18 RS Electronic Gold Tester includes testing acids, a user manual, and possibly cleaning supplies to maintain the device. These accessories enhance user experience by providing everything necessary for effective testing right out of the box. It is useful in ensuring that users can seamlessly start their testing process without needing additional purchases, which can be especially beneficial for those starting in the jewelry business. -
Question:
Is the ET18 RS portable for travel?
Answer: Yes, the ET18 RS is designed with portability in mind, usually coming in a compact size that makes it easy to carry to various locations, including trade shows or exhibitions. Its lightweight construction and durable casing allow for hassle-free transport without worrying about damaging the device. Professionals in the jewelry industry often appreciate its portability, enabling them to conduct on-the-go testing whenever needed. -
Question:
What is the calibration process for the ET18 RS?
Answer: Calibration of the ET18 RS is typically straightforward and involves using a calibration piece or following specific instructions in the user manual. This ensures ongoing accuracy and reliability of the results. Regular calibration is essential for professionals who rely on precise readings for transactions or appraisals, as it helps maintain confidence in the device's outputs over time. -

Arikit Gold Testers Editorial Review
Mizar Et18 RS Electronic Gold Tester is a compact and battery-powered device designed for measuring gold quality accurately. However, some users have raised concerns about its limitations in testing gold plating, as it may mistakenly register plated jewelry as solid gold. The device operates at a minimum voltage of 9 volts and is certified with CE, RoHS, and UL standards, ensuring reliability. While many found it effective for authenticating their gold pieces, there are mixed reviews regarding its accuracy with lower karat items. Overall, it's a useful tool for enthusiasts and professionals, though caution is advised for plated items.
