High Accuracy Sample Weighing from Exceptional Sensitivity

Perfect for meeting weighing conditions of clinical and pharmaceutical labs, schools, and food manufacturing facilities to name a few, the UW420H Precision Scale from Shimadzu lets you to weigh particulate matter and a variety of minute samples confidently. Determining variations in mass with its 1 mg readability, the Shimadzu UW420H precision balance utilizes your lab budget to an great advantage while providing not just accurate weighing performance but also effective sample handling for your industrial applications, manufacturing operations, or daily laboratory tasks,. Not what you exactly need? The UW1020H Precision Scale from Shimadzu also offers the same 1 mg readability. You might want to check it instead. But if you need a model having a higher readability, check the UW6200H Precision Scale from Shimadzu.

All-out Repeatability for Efficient Sample Weighing

Maintain reproducible measurement values throughout your weighing process to achieve valid results and save more time to do data analysis than re-recording data with the Shimadzu UW420H lab scale. Thanks to its repeatability of 1 mg, this Shimadzu UW model brings about precise sample weighing for routine applications even with multiple users controlling the unit. Alternatives with a higher repeatability value include the PS 10100.3Y Precision Balance from Radwag, an equally well-known brand.

Functional Sample Weighing for Lab, Field, and More

Whether executing tasks inside a laboratory or out in the field, the Shimadzu UW420H brings in accuracy and precision in weighing at all times through its external calibration feature that manually calibrates the model using endorsed test weights to validate measurements. Complete with a 108 mm pan, this weighing scale can have room for a max of 420 g of samples so make it to a point that your load will not be over this. A great option for a higher capacity unit but with the same readability as the Shimadzu UW420H would be the UW1020H Precision Scale from Shimadzu or the Adventurer AX523N/E Precision Scale from Ohaus.Need a different model but with just the same capacity as this unit? You can get the UW420S Precision Scale from Shimadzu instead.
