Design and Build
The Bonvoisin 5000gx0.01g features a functional and durable design centered around its large, stainless steel weighing pan. The 180mm by 140mm pan provides a generous surface area for weighing bulky or multiple items, from lab beakers to cast iron cookware, as noted by users. The base incorporates a non-slip mat, enhancing stability on various surfaces—a practical touch for different weighing environments like workshop benches or kitchen counters.
Built-in adjustable feet and a level bubble allow users to ensure the scale is perfectly horizontal, which is critical for achieving accurate readings. The unit is described as having a mini form factor, suggesting a relatively compact footprint suitable for bench-top use. The overall construction, highlighted by the stainless steel pan, points toward a build intended for regular use, though specific details about the durability of the housing material are not explicitly listed by the manufacturer.
Performance and Features
Precision and Accuracy
The core promise of the Bonvoisin 5000gx0.01g is its 0.01-gram precision across its full 5000-gram range. This is achieved through what the manufacturer describes as an “upgraded high-sensitivity built-in sensor.” User reviews confirm this sensitivity in real-world applications, from measuring food nutrients to weighing rolls of filament for 3D printing. The scale includes features to support this accuracy: an overload alarm, error indication, and the necessity for periodic external calibration. It is important to note that calibration weights are not included with this 5000-gram model, as their weight could damage the scale during shipping.
Functional Versatility
Beyond basic weighing, the scale includes several functions that increase its utility. The tare function allows the weight of a container to be subtracted instantly. The parts counting function is designed for inventory tasks, enabling the counting of small, identical items like pins or nuts after calibrating with a sample. A memory function is also present, though its specific operation is not detailed in the provided data.
The unit conversion feature is a significant strength, offering instant switching between thirteen units including grams, carats, ounces (avoirdupois and troy), pounds, pennyweights, and grains. This makes the scale adaptable for jewelers, pharmacists, chefs, and others who work across different measurement systems. However, one user highlighted a drawback: the percentage function, useful for tasks like mixing epoxy, is non-intuitive and not covered in the manual, requiring a specific, discovered procedure to activate.
Display and Power
The large LCD display is noted for being easy to read, even in low-light conditions, which aids in error-free data recording. The scale offers dual power options, operating via an included 110V AC adapter or a 9V battery. This battery capability provides portability, allowing the scale to be used in locations without immediate access to a power outlet.
Setup, Support and Ownership
Initial setup involves placing the scale on a level surface using the adjustable feet and bubble indicator. For optimal accuracy, external calibration is recommended periodically using appropriate calibration weights, which must be sourced separately for this model. The manufacturer offers a one-year warranty, promising to help replace the scale or charger if problems occur. Customer service appears responsive, with one review noting that the company sent a new calibration weight when a scale arrived slightly out of spec, resolving the issue satisfactorily.
Ownership entails an awareness of environmental influences on precision weighing, a point the manufacturer acknowledges. The scale includes fault visualization to help diagnose issues. Users should also be aware of the “hidden menu” mentioned in one review, which allows changing settings not explained in the manual; tinkering here can alter the scale’s maximum capacity and resolution, so caution is advised.
What Owners Say
Owner feedback is overwhelmingly positive, contributing to the scale’s high rating. Reviews frequently praise its “fantastic” sensitivity and “unbelievable” precision for the price, with many users successfully employing it in kitchens for calorie tracking and in home labs for various projects. The large capacity that can handle heavy items like a full skillet is a repeatedly mentioned benefit. The counting function and unit conversion are also valued.
The primary criticisms relate to the learning curve for certain advanced functions and the lack of included calibration weights. The percentage function’s obscure operation is a noted con, and one user expressed a desire for clearer instructions. The rating distribution shows most users are highly satisfied, with a smaller percentage reporting issues typically related to setup or specific feature use.
