High Accuracy Weighing from Outstanding Sensitivity

Take champion value for your laboratory budget without compromising weighing ability through the Pioneer PX4201 Precision Scale from Ohaus. Built with a 100 mg readability, the Ohaus PX4201 presents accurate sample weighing even if working on lab manufacturing, or industrial applications. Rolling out close weighing results, this laboratory scale warrants clear-cut weighing suited for quality control processes, laboratory tasks, manufacturing operations, and more. In need of other precision scale options with a similar 100 mg resolution? Opt for the Pioneer PX4201/E Precision Scale from Ohaus. But if you want a model having a higher readability, check out the Pioneer PX2202/E Precision Scale from Ohaus.

Unquestionable Repeatability for Dependable Mass Weighing

Through the Ohaus PX4201, having multi users managing the unit is not a problem when it comes to acquiring results that can be reproduced. Presenting a 100 mg repeatability, this Ohaus top loading balance generates similar sample weighing values presuming that similar conditions are followed so it is perfect for everyday weighing applications. Since you get precise measurement values, you can spend more time for results analysis instead of re-recording data each and every time. Still undecided and thinking of a unit with a higher repeatability value? Check the Pioneer PX2202 Precision Scale from Ohaus instead.

Multipurpose Weighing Performance At Any Time or Place

Reviewing how many samples you'll be weighing in the future is one thing to think about right before purchasing a balance. It is important to make sure that the model you are acquiring can carry your anticipated sample loads. With the Pioneer PX4201 Precision Scale from Ohaus, you can take in up to a maximum of 4200 g samples. Weighing precision and accuracy is verified by the Ohaus PX4201 as it features internal calibration, therefore it can recalibrate anytime and anywhere. Do you need a higher capacity model? You can pick the WLY 20/D2 Precision Balance from Radwag instead. Another model but with the same capacity as this lab scale that you can get the Pioneer PX4201/E Precision Scale from Ohaus instead.

Loaded with Noteworthy Features

Internal Calibration icon Internal Calibration

Capable of self-recalibration through its internal calibration feature, the Ohaus Pioneer laboratory scale exhibits accuracy and precision even if moved from a spot to another. Including an internal calibration feat, the unit can also consider changes in time, temperature, movement, and stability to name a few and then adapt as required.

ISO compliant icon ISO Compliant

Achieve a more effective workflow and meet user requirements with this laboratory scale that heeds to high quality risk-based management systems and prints out reports compliant to ISO.

GLP Compliant icon GLP Compliant

Carry out quality control measures without a fuss with this Ohaus precision scale as it already produces GLP-compliant reports complete with balance ID, time, date, and more to assist with your research or experiment record keeping, checkpoints, and protocols.

GMP Compliant icon GMP Compliant

Delivering reports compliant to GMP, the Pioneer PX4201 Precision Scale from Ohaus prints out reports with results, operator details, and weighing time included. This makes it a recommended top loading balance for doing testing and quality control on manufactured food, goods, raw materials, drugs, and more.

LCD screen icon LCD Screen

Viewing measurement results will not be a problem even if you are in badly-lit areas because this Ohaus 30429844 precision balance is armed with a high contrast LCD screen. You are guaranteed crisp display of measurement weighing values every time so user-related errors such us data readout slip-ups are reduced.

Operational Excellence Spelled Out

Have more time in your hands to do other prio activities with the Ohaus PX4201 as it rolls out measurement weighing results in 1.0 second. It can also transfer acquired data and results to devices remotely close to the unit in less than a minute since it has built-in RS-232 and USB ports. Additionally, reformatting reports will never consume your time anymore because the lab scale already abides by the GMP, GLP, and ISO print format.

    Sometimes I could use a little more space in the pan. Best part is the response time and automatic calibration. Easy to clean too.
