High Accuracy Weighing Coming from Exceptional Sensitivity

The Explorer EX1103 Precision Scale from Ohaus returns highly accurate weighing of particulate matter or other minute samples thanks to its 1 mg resolution. Hard-wearing and constructed for use not just in laboratories but also even for industrial facilities, production houses, or schools, the Ohaus EX1103 shows reliable and close measurement values, assuring cost-efficient weighing for quality control processes, laboratory tasks, as well as manufacturing procedures. Another option with the same 1 mg resolution that you can decide on is the the Explorer EX423N Precision Scale from Ohaus from the same Explorer series.

Unadulturated Reproducibility for Efficient Sample Weighing

Spend more time on results analysis than data transcription with the Ohaus EX1103 precision scale. Putting forward a 1 mg repeatability, the Explorer EX1103 Precision Scale from Ohaus leads to constant sample weighing values so it's unecessary to go back to start whenever they reproduce their expreiment or research. Obtain unambiguous measurement values all throughout your weighing process, even with multi-users considered, for reputable results when it comes to routine weighing applications. If you require a model offering a higher repeatability value though, go for the PS 6100.3Y Precision Balance from Radwag.

Multipurpose Sample Weighing At Any Time or Place

Before procuring a precision scale, make sure you anticipate the sample load you will be weighing at present and in the future. These should always be within a model's capacity range and won't overflow from its weighing pan. Using the Ohaus EX1103, you can cover various samples, as long as these do not exceed 1100 g at max and its 130 mm weighing pan. As the top-loading scale features internal calibration, permitting fast self re-calibration anytime it is needed, weighing accuracy and precision will not be an issue. You can settle with the Explorer EX2202 Precision Scale from Ohaus if you are experimenting on heavier samples. But if you need something similar to this Explorer unit but of a different model or from another globally trusted brand, get the Explorer EX1103N Precision Scale from Ohaus
