Description
Key Selling Points
- 0.01g (10mg) accuracy with electromagnetic force-balanced load cell — consistent, repeatable readings for gemstone and precious metal weighing
- 2100g maximum capacity covers the full range from individual gemstones to larger jewelry pieces and metal stock
- 9 weighing units in one balance: g, kg, T, GN, OZ, dwt, ct, lb, ozt — switch with a single key press without recalibrating
- 1kg calibration weight included — one-touch calibration keeps the balance accurate over time without sourcing a separate weight
- 125mm (4.9 in) stainless steel tray resists corrosion and is easy to clean between weighing sessions
- Built-in leveling device and adjustable non-slip feet ensure a stable, level weighing surface on any bench
About This Balance
The Tooltos Digital Precision Balance is designed for jewelers, gemologists, and laboratory professionals who need reliable 0.01g accuracy for daily weighing tasks. The electromagnetic force-balanced load cell delivers fast, stable readings across the full 2100g capacity range — from a single small gemstone to a batch of metal castings — without the drift that affects lower-grade spring-based scales.
The nine built-in weighing units cover the full range of jewelry and precious metals measurement: carats (ct) for gemstones, pennyweight (dwt) and troy ounces (ozt) for gold and silver, and standard metric and imperial units for general use. The included 1kg calibration weight and one-touch calibration function make it straightforward to verify and restore accuracy without sending the balance for external calibration.

Best For / Not For
| Best For | Not For |
|---|---|
| Jewelers weighing gold, silver, and platinum in grams, pennyweight, and troy ounces | 110V power supplies — this balance is 220V only. A step-up transformer is required for North America |
| Gemologists weighing and grading stones in carats with 0.01g precision | Environments with strong magnetic fields, vibration, or air currents — these affect electromagnetic balance accuracy |
| Laboratory technicians requiring multi-unit precision measurement up to 2100g | Weighing items above 2100g (4.6 lb) — the maximum capacity is 2100g |
| Jewelry schools and training workshops needing a reliable, calibratable precision balance | Analytical laboratory work requiring 0.001g or finer precision — this balance reads to 0.01g |

Pro Tips
- Place the balance on a stable, vibration-free surface away from air conditioning vents and open windows — air currents cause the reading to fluctuate and reduce accuracy.
- Use the built-in leveling device and adjust the feet until the bubble is centered before each weighing session — an unlevel balance introduces systematic error into every reading.
- Calibrate with the included 1kg weight at the start of each day or after moving the balance to a new location — electromagnetic balances can drift slightly after transport.
- Allow the balance to warm up for 5-10 minutes after switching on before taking precision measurements — the load cell stabilizes to ambient temperature during this period.
- Handle the calibration weight with clean, dry hands or tweezers — fingerprint oils and moisture add measurable weight and can affect calibration accuracy over time.
Frequently Asked Questions
Does this balance work on 110V?
No. This balance operates on 220V only. There is no 110V version. For use in North America or other 110V regions, a step-up transformer is required.
What is the accuracy and maximum capacity?
The balance reads to 0.01g (10mg) accuracy with a maximum capacity of 2100g (4.6 lb). It is not suitable for items above 2100g or for applications requiring finer than 0.01g precision.
Can I weigh gemstones in carats and gold in pennyweight?
Yes. The balance includes both carat (ct) for gemstone weighing and pennyweight (dwt) for gold and silver, along with troy ounces (ozt) for precious metals trading. Switch between units with a single key press.
How often should I calibrate the balance?
Calibrate at the start of each working day and after moving the balance to a new location. The included 1kg weight and one-touch calibration function make this a quick process. Regular calibration is the most important factor in maintaining consistent accuracy.
What environments affect the accuracy of this balance?
Strong magnetic fields, vibration, air currents, and extreme temperatures all affect electromagnetic balance accuracy. Place the balance on a stable bench away from magnetic tools, HVAC vents, and sources of vibration for best results.
