High Accuracy Weighing Measurements Backed by Outstanding Sensitivity

The Pioneer PX323/E Precision Scale from Ohaus has you covered for all your weighing needs. Built to determine mass variations by its 1 mg readability, the Ohaus PX323/E warrants high performance weighing of particulate matter or tiny samples, securing reliable measurement values. Even if focusing on weighing tasks of chemistry applications, pharmaceutical and medical studies, industrial and production operations, or food and textile industry, this 1 mg readability model presents uncomplicated weighing.

Ultimate Repeatability for Powerful Mass Weighing

Thanks to the Ohaus PX323/E, having multi users controlling the balance is never a problem when it comes to acquiring results that can be reproduced. Exhibiting a 1 mg repeatability, this Ohaus laboratory scale yields almost the same weighing values provided that the same settings are implemented, making it perfect for routine weighing applications. Given that you obtain precise measurement values, you can allot more time analyzing your results instead of re-recording these every time. Still unsure and looking for something having a higher repeatability value? Check the PS 8100.3Y Precision Balance from Radwag instead.

Ingenious Weighing for Lab, Field, and More

Whether working on tasks out in the field or in a laboratory, the Ohaus PX323/E brings in precision and accuracy in weighing at all times through its external calibration feat, allowing hassle-free manual calibration by using approved test weights to confirm measurements. Be sure your load would not exceed 320 g as this is the maximum the unit can accommodate. A good option for a higher capacity unit but with the same readability as the Ohaus PX323/E would be the Pioneer PX523 Precision Scale from Ohaus or the PS 1000.X2 Precision Balance from Radwag.Need a different model but with just the same capacity as this unit? You can get from the Pioneer PX323 Precision Scale from Ohaus instead.
