Exceptional Sensitivity for High Accuracy Weighing Measurements

Obtain exceptional value for your budget without compromising weighing power through the UW420S Precision Scale from Shimadzu. Engineered with a 0.01 mg sensitivity, the Shimadzu UW420S prompts accurate sample weighing even if working on manufacturing, lab, or industrial applications. Introducing close and reliable weighing results, this precision balance assures clear-cut weighing suggested for manufacturing procedures, lab tasks, quality control requirements, and more. In need of other lab scale options with the same 0.01 mg division size? Opt for the UW2200H Precision Scale from Shimadzu.

Unquestionable Reproducibility for Efficient Mass Weighing

Obtain credible results, maintain replicable measurement values all throughout your weighing process, and allot more time actually analyzing data than re-recording data with the Shimadzu UW420S top loading balance. This Shimadzu UW model returns precise sample weighing ideal for daily applications thanks to its 8 mg repeatability.For a substitute with a higher repeatability, your choices include the UW420H Precision Scale from Shimadzu from the same manufacturer and series.

Multi-Purpose Weighing from Laboratory to Field

Cover 420 g of materials through this Shimadzu model engineered with a 108 mm weighing pan. Whether dealing with solids, liquids, and other sample types or working in the lab or field, this top loading balance verifies weighing precision and accuracy through its external calibration feature. Low-cost than self-calibrating ones plus more appealing to facilities on a tighter budget and have the capacity to spend additional time when it comes to doing constant calibration, the Shimadzu UW420S presents manual calibration using test weights approved.You can settle with The UW2200H Precision Scale from Shimadzu if you are dealing with hefty samples but still require the same readability as the Shimadzu UW420S.

Highlighted Features to Consider for Hassle-free Weighing

ISO compliant icon ISO Compliant

Fulfill application requirements with this ISO-compliant lab scale, standing by rigorous measures when it comes to routine testing, calibration, preventative maintenance and more, its print guidelines, the highest quality risk-based management systems.

GLP Compliant icon GLP Compliant

Returning GLP-compliant reports with date, time, balance ID, and other relevant data, this Shimadzu balance model offers effortless tracking down of activities for your case study, ensuring data credibility. There is no more need towaste time reformatting anything ever again.

GMP Compliant icon GMP Compliant

Conforming to GMP standards that set high importance to quality management and assurance, the UW420S Precision Scale from Shimadzu prints out reports complete with operator details, weighing time, and results to name a few. Because of this, it is an excellent unit to consider for food and drug processing, manufacturing, and packaging industries that put high importance on quality testing and management.

Alphanumeric LCD icon Alpha Numeric LCD

Clear visibility of measurement data is assured by the Shimadzu UW420S featuring a heavy-duty Alphanumeric LCD screen. Because users then avoid misreading measurement values, even if they are inside badly lit locations, getting improved operational efficiency is no-sweat.

Unequivocal Operational Efficiency

Have more time in your hands to do other priority tasks through the Shimadzu UW420S as it produces results within 0.7 seconds. It can also transmit acquired weighing results to devices remotely close to the unit in a short period of time since it has built-in USB and RS-232 ports. There is no need to reformat reports as well because the precision scale already follows the GLP, ISO, and GMP print format.

The new line of Shimadzu top-loading balances are engineered with the innovative UniBloc mechanism which brings superior impact resistance unrivaled quick response, excellent stability and durability at the same time. Powerful features support any imaginable weighing application. UW Series comes with motor-diven built-in calibration weight and fully-automatic calibration functions.

UniBloc technology and benefits

The traditional core assembly of the electro-magnetic balance is replaced by a single part, the aluminum Shimadzu UniBloc. Digitally controlled wire-cut electric discharge processing makes it possible. This technology, which Shimadzu introduced in our EB-K precision platform balances as early as 1989, brings excellent benefits to the operator. Quick response, stability against temperature change, and outstanding durability. (Patented in USA in 1989, No.4799561, in China in 1991, No.12729, in Japan in 1995, No.1905686)


Built-in Clock GLP/GMP/ISO Conformance

Display during standby Best for establishing administrative system to meet requirements of GLP/GMP/ISO9000. Calibration records can be provided with date and time.

Analog display modes

Full range display mode

Full range Bar graph clearly indicates the total weight (including the tare) as a portion of the balance capacity.


Select a target weight and tolerance. The display clearly indicates when they are reached.


Set an upper and lower limit. The display continually indicates whether the sample is within the range "GO", over range "HI" or under range "LO". Choose one of the two bar graph display modes.

LCD with backlight

LCD with backlight can be read with ease and comfort in any location without brightness adjustment.

Windows(R) Direct function

The balance communicates directly to a PC with WindowsTM applications. No additional software is needed to interface with spreadsheet, database, word processing, and laboratory software.

Windows(R) Direct function works Windows(R) 95, 98, 2000, NT4.0, Me and XP. PC must be IBM PC/AT compatible.

Unit conversion

Weight value is presented in 22 units and modes, including percentage, carat, specific gravity, lb, oz, and so on. Users can choose any combination of units depending on their needs. Piece counting function Piece counting function is installed as standard.
