High Accuracy Sample Weighing Backed by Superior Sensitivity

The Pioneer PX523 Precision Scale from Ohaus provides high-accuracy weighing of particulate matter or other small samples made possible by its 1 mg division size. Heavy-duty and engineered for use not just in laboratories but also even for universities, production houses, or industrial facilities, the Ohaus PX523 shows close and reliable measurement values, assuring cost-efficient weighing for manufacturing purposes, daily lab tasks, as well as quality control processes. Another modelat par with this balance that you can consider is the Pioneer PX323/E Precision Scale from Ohaus.

Highly Precise Measurement Values for Effective Sample Weighing

Obtain consistent values throughout your weighing process to set asides more time analyzing data rather than re-transcribing these each time with the Ohaus PX523 scale. Having a repeatability of 1 mg, this Ohaus precision scale returns precise measurement values best for routine weighing applications, no matter how many users control it and as long as similar conditions are implemented. Opt for the PS 8100.3Y Precision Balance from Radwag instead if you need a unit with a higher repeatability.

Essential Weighing Wherever You May Be

Carry 520 g of substances through this Ohaus model. Whether working in the laboratory or field or weighing solids, chemical, and other sample types, this balance secures accuracy and precision through its internal calibration feat. No need to worry even if you move the unit from a place to another because it can self-calibrate accordingly when required.Experimenting on heavier samples? You can settle with the Pioneer PX523/E Precision Scale from Ohaus.

Significant Features to Take Into Account

Internal Calibration icon Internal Calibration

This Ohaus Pioneer precision scale has an internal calibration feature, adjusting as needed to consider variance in time, movement, temperature, and stability. This assures weighing accuracy even if the unit is moved daily.

ISO compliant icon ISO Compliant

The laboratory scale is compliant to ISO standards, following strict measures when it comes to preventative maintenance, routine testing, calibration, and more as well as its print guidelines.

GLP Compliant icon GLP Compliant

Producing reports compliant to GLP, this Ohaus precision scale permits you to breezily track task history of your experiment being focused on. Reduce time formatting reports with this model as you get to have these following criteria of GLP, complete with time, balance ID, date, and more perfect for record keeping and quality purposes.

GMP Compliant icon GMP Compliant

If you place high significance on quality management, testing, and processing of manufactured goods including raw materials, goods, food, and drugs, then this Ohaus 30430054 top loading scale is suitable for you. Abiding by GMP regulations, this model prints out already formatted reports that include weighing time, results, and operator deatils.

LCD screen icon LCD Screen

It wouldn't really matter if the Ohaus 30430054 balance is positioned in areas with bad lighting conditions since it is armed with a bright LCD screen. Sharp reading data is guaranteed so blunders caused by users when it comes to reading measurement results are decreased.

Proven Operational Efficiency At Your Fingertips

With a stabilization time of 2.0 seconds, the Pioneer PX523 Precision Scale from Ohaus is able to show weighing values already, helping raise lab output in the process. Moreover, users reach better workflows as this laboratory scale has built-in USB and RS-232 ports for quick transfer of data to multiple computers, devices, and even printers. Make space for more time and re-allocate it to other higher priority activities because the precision scale abides by GLP, GMP, and ISO regulations, therefore already generating compliant reports so reformatting these will never be an issue.

The Pioneer PX combines essential weighing functionality with competitive performance, offering high accuracy and repeatability for applications in laboratory, industrial and education settings. The PX is affordably priced, and intuitively designed for intelligent operation with a second line display for additional information, and USB and RS232 connectivity for easy communication.
