Bonvoisin Lab Scale 5000g 0.01g Precision Analytical Balance - Updated

In this review the Bonvoisin Lab Scale 5000g/0.01g is examined for lab, jewelry and kitchen use; its single biggest selling point is the combination of a large stainless steel weighing pan and fine 0.01 g resolution that make it practical for small parts, powders and precision tasks. The reviewer found the updated features - a larger plate, USB interface for data transfer and a broadened battery compartment - to be useful real-world improvements that reduce handling time and improve workflow when recording or printing results.

Key Features

• 0.01 g Resolution: Delivers high precision for small samples and jewelry, with a minimum reliable weighing around 0.05 g for accurate measurements.
• Large Stainless Steel Pan: The enlarged 7.2 x 7.2 in pan allows weighing multiple items or larger containers without crowding the sensor area.
• USB Interface: Enables serial data exchange to a computer or micro-printer so results can be sent directly into office software for logging and analysis.
• 13 Unit Conversions: Quickly switch among grams, carats, ounces, pounds and other units for flexible use across lab, jewelry and kitchen tasks.
• Dual Power Sources: Works from the included 110V adapter or a 9V battery for portable use; the battery compartment was broadened for easier installation.
• Protective Design: Detachable pan and a membrane over controls and screen help protect the scale from light splashes and simplify cleaning.

Who It's For

The Bonvoisin 5000g analytical balance is aimed at small laboratories, jewelers and hobbyists who need a large pan plus fine resolution for repeatable measurements. Its USB output makes it especially practical for users who record results digitally or need printed records without manual transcription. The tare, counting and multi-point calibration functions make it useful for inventory tasks and repetitive weighing jobs.

Those who need sub-0.01 g resolution, included calibration weights, or a data cable in the box should look elsewhere; calibration weights and the data cable are sold separately, and the unit does not include every accessory needed for some regulated laboratory settings.

Pros & Cons

Pros

• High 0.01 g resolution with a practical 0.05 g minimum for many small-sample applications.
• Large, detachable stainless steel pan simplifies batch weighing and cleaning.
• USB data output streamlines recording results directly into office software or a printer.
• Multiple unit conversions and built-in counting and tare improve everyday versatility.

Cons

• Calibration weight and data cable are not included, so additional purchases may be required for precise calibration or data transfer.
• For ultra-trace analysis below 0.05 g or regulated lab certification, a higher-spec analytical balance may be necessary.

Our Verdict

The Bonvoisin Lab Scale 5000g/0.01g is a practical, value-focused analytical balance for labs, jewelers and small businesses that need a large pan and accurate, repeatable measurements. Its updated large plate, USB output and easier battery access address common usability issues, making it a solid choice when you need reliable precision without enterprise-level cost - just budget separately for a calibration weight and data cable if required.

Frequently Asked Questions

Is the USB data cable included?
The USB data cable is not included and must be purchased separately to enable direct computer or printer connections.

Does the scale include calibration weights?
Calibration weights are not included; purchase the correct calibration weight separately if you plan to perform certified calibrations.

Can it run on battery for portable use?
Yes, it accepts a 9V battery for portable operation, though the battery is not included; the compartment has been broadened for easier installation.
