Outstanding Sensitivity for High Accuracy Measurements

Obtain exceptional value for your budget while not compromising weighing effectiveness with the Explorer EX623 Precision Scale from Ohaus. Constructed with a 1 mg sensitivity, the Ohaus EX623 presents accurate sample weighing values whether doing industrial, lab, or manufacturing applications. Generating close and reliable weighing results, this balance warrants straightforward weighing for manufacturing procedures, routine laboratory tasks, quality control processes, and more. In need of other scale options with a similar 1 mg sensitivity? Go for the Explorer EX423 Precision Scale from Ohaus.

Highly Precise Measurement Values for Powerful Sample Weighing

Yield reproducible values throughout your weighing process to spend more time for data analysis rather than re-transcribing these each time with the Ohaus EX623 precision scale. Showcasing a 1 mg repeatability, this Ohaus balance leads to high precision measurement values ideal for routinary weighing applications, no matter how many users control it and so long as the same weighing conditions are implemented. Opt for the PS 6100.3Y Precision Balance from Radwag instead if you are looking for something with a higher repeatability.

All-Around Weighing Solutions No Matter Where You Are

Whether implementing activities out in the field or inside a laboratory, the Ohaus EX623 leads to precise and accurate weighing at all times through its internal calibration feat, steadily adjusting despite being moved from an area to another. Be sure your sample load would not exceed 620 g as this is the maximum the balance can accommodate with its 130 mm pan. A great option for a higher capacity unit would be the Explorer EX4202/E Precision Scale from Ohaus.
