Bonvoisin Lab Scale 1000g x 0.01g High Precision Analytical Balance

In this review the Bonvoisin Lab Scale 1000g x 0.01g is assessed for small-lab and hobby use, with the bottom line that it is a practical, accurate analytical balance for users who need fine resolution without a lab-sized budget. The reviewer found the single biggest reason to buy is the 0.01g high precision across multiple selectable ranges, which makes it suitable for jewelry, small chemical samples, and detailed counting tasks while remaining compact and straightforward to operate.

Key Features

• High precision: The scale offers 0.01g resolution and eight selectable ranges that provide repeatable small-mass readings for jewelry and lab samples.
• Large stainless pan: A 180 x 140mm stainless steel weighing pan handles multiple items at once and cleans easily after use.
• Built-in stability aids: Adjustable feet and a level bubble help ensure the balance sits correctly for consistent measurements.
• Multiple functions: Tare, memory, counting and fault visualization make routine tasks like batching and piece counting straightforward.
• Wide unit conversion: Thirteen unit options including g, ct, oz, ozt and lb provide flexibility for different workflows.
• External calibration: The ability to calibrate externally (with included weights for many ranges) keeps accuracy stable over time.

Who It's For

The Bonvoisin balance is aimed at small laboratories, jewelers, watchmakers, and hobbyists who need precise 0.01g readings without investing in industrial equipment. It works well for counting small parts, weighing powders for experiments, or checking precious metal weights where repeatability matters.

It is less suited to heavy industrial environments where larger capacities or ruggedized casings are required, or to users who need laboratory-grade environmental enclosures for extremely sensitive metrology. Buyers who expect flawless stability in drafty, unlevel conditions should consider a balance with a draft shield or vibration isolation.

Pros & Cons

Pros

• Accurate 0.01g resolution across selectable ranges offers good precision for jewelry and lab tasks.
• Large stainless steel pan and non-slip mat make handling multiple and small items convenient.
• Multiple built-in functions and broad unit conversion increase day-to-day versatility.
• External calibration and included weights (for most ranges) support long-term accuracy and easy recalibration.

Cons

• Some users report occasional fluctuating readings, so environmental control is important for best results.
• Calibration weights are not included for the highest capacity (5000g) model, which may limit out-of-the-box setup for that range.

It offers good value through a large stainless pan, multiple functions and external calibration, though users should control the weighing environment to avoid occasional fluctuations in readings.

Frequently Asked Questions

Does this scale need calibration?
Yes, it supports external calibration and calibration weights are included for scales in the 200g-3000g ranges to maintain accuracy.

Can it weigh multiple small items like jewelry and screws?
Yes, the large 180 x 140mm stainless steel pan and non-slip mat allow weighing multiple items at once while protecting the pan.

Are calibration weights included for the 5000g model?
No, calibration weights are not included for the 5000g version due to shipping concerns with heavy weights.
