The Infyniti SPA20 is a high-precision digital scale made for weighing small, valuable items like gemstones or powders. Its 0.001g readability and 20g capacity make it an excellent choice for jewelers and hobbyists.
When your measurements require absolute precision, this compact scale provides accuracy down to a single milligram (0.001g). It is designed for professionals and hobbyists who handle high-value materials. Its portable design and full accessory kit make it a complete weighing solution right out of the box.
The SPA20’s high sensitivity makes it the perfect tool for tasks where tiny variations matter. We recommend it for jewelers weighing diamonds, lab work with powders, or anyone needing exact micro-measurements. The ability to switch between grams, carats, and ounces makes it versatile for many professional jobs.
The value of an accurate milligram scale comes from its components and capabilities. The Infyniti SPA20 combines sensitive measurement technology with user-friendly features to give you trustworthy results every time.
A readability of 0.001g means the scale can detect and show weight changes as small as one-thousandth of a gram. This level of detail is critical for valuing gemstones or preparing precise compounds. It ensures you are getting a true, fine-grained measurement, not just a guess.
| Specification | Value | Your Benefit |
|---|---|---|
| 0.001 g Readability | Measures in increments of a single milligram. | Get high accuracy for valuable items like diamonds and powders. |
| 20 g Maximum Capacity | Can weigh items up to 20 grams (about 0.7 oz). | Perfect for individual gemstones, jewelry parts, and small batches. |
| Multiple Weighing Units | Switches between g, oz, ozt, dwt, ct, and gn. | Work in the units you need without manual conversion, saving time. |
| Included 20g Calibration Weight | A certified 20-gram weight is included in the box. | Maintain accuracy over time by easily calibrating the scale. |
| Protective Flip-Top Cover | Acts as a draft shield for the weighing surface. | Reduces random changes from air currents for more stable readings. |
Beyond its core precision, the SPA20 includes thoughtful features that simplify the weighing process. From the easy-to-read display to the full set of included tools, every part is designed for convenience and accuracy.
This scale is a complete kit, ready for use right away. Inside the box, you will find the SPA20 scale, a 20g calibration weight, a small weighing tray, precision tweezers for handling items, and two AAA batteries. You won’t need to buy separate accessories to get started.
The Tare function lets you zero out the weight of a container to measure only the contents. Place your empty tray on the scale, press the "Tare" button to reset the display to zero, and then add your material. This is crucial for accurately weighing powders or other substances in a container.
Choosing the right scale depends on your needs for capacity and precision. The Infyniti SPA20 is best for high-precision, low-capacity tasks. Here’s how it compares to other common types of digital scales.
Compared to a standard 0.01g pocket scale, the SPA20 is ten times more precise, making it much better for milligram-level work. While scales with a higher capacity, like a 50g model, can handle larger items, they may not offer the same 0.001g readability. The SPA20 is a great choice for anyone who values precision over total capacity.
| Model | Readability | Capacity | Best For |
|---|---|---|---|
| Infyniti SPA20 (This Product) | 0.001 g | 20 g | Diamonds, Powders, Lab Use |
| Standard 0.01g Pocket Scale | 0.01 g | 100 g | General use, herbs, larger items |
| 50g Milligram Scale | 0.001 g | 50 g | Larger gemstones, small batch mixing |
| High-Capacity Gram Scale | 0.1 g | 500 g+ | Kitchen use, shipping, bulk materials |
Proper care is essential for maintaining the accuracy of a sensitive instrument like the SPA20. Regular calibration and a stable environment will ensure you get reliable measurements for years to come.
Calibrating your scale is simple using the included 20g weight. Place the scale on a flat, stable surface away from drafts and turn it on. Wait for it to read "0.000". Press and hold the "Mode" button until the display shows "CAL", then release. The screen will flash "20.000". Gently place the 20g weight on the platform's center and wait. The display will show "PASS" and return to weighing mode. Your scale is now calibrated.
Small changes in the reading are common with 0.001g scales because they are so sensitive. The usual causes are air currents from vents or breathing, vibrations from a shaky table, or interference from cell phones. Using the protective cover as a draft shield and weighing in a calm, stable spot will help you get a steady reading.
