High Accuracy Weighing Measurements Coming from Superior Sensitivity

The Explorer EX223 Precision Scale from Ohaus provides highly accurate weighing of small samples or particulate matter thanks to its 1 mg resolution. Durable and designed for use not just in labs but also even for production houses, industrial facilities, or schools, the Ohaus EX223 shows close measurement values, ensuring cost-effective weighing for manufacturing purposes, quality control processes, as well as routine laboratory tasks. Finding other precision balance alternatives with a similar 1 mg resolution? Go for the Explorer EX623 Precision Scale from Ohaus.

Highly Reproducible Measurements for Powerful Sample Weighing

When it comes to achieving results that can be replicated for applications done on a regular basis, you can depend on the Explorer EX223 Precision Scale from Ohaus that provides 1 mg repeatability. Even with multiple users considered, the unit yields high precision weighing measurement values all throughout your complete weighing process for valid results, that is of course considering similar settings are carried out. If you require higher repeatability from the same MFG or another industry celebrated brand, opt for the PS 10100.3Y Precision Balance from Radwag

Multipurpose Sample Weighing Wherever You May Be

The Ohaus EX223 allows you to hold 220 g of sample load at maximum with its spacious 130 mm pan. Weighing precision and accuracy for the smallest quantities of substances is validated with the unit's internal calibration feat for quick self-recalibration anytime or anywhere. For activities that deal with heavier samples, possible replacements to check include the Explorer EX6201 Precision Scale from Ohaus with a higher weighing capacity than this Ohaus Explorer model. If you just need a different model but with the same capacity as this laboratory scale, you can do from the Explorer EX223/E Precision Scale from Ohaus instead.
