Resistance to dirt and chemicals: High-quality, robust housing for professional continuous use
The balance offers fast stabilisation times, an automatic adjustment function (depending on the model) and supports various weight units to facilitate the measurement of different substances. Its special features include comprehensive protection against chemical influences and contamination, which significantly increases the service life of the balance in daily operation.
Thanks to the precise strain gauge load cell made from state-of-the-art materials, even demanding analyses can be carried out with minimal potential for error. The sophisticated software ensures easy calibration - data transfer can also be integrated into digital laboratory structures if required (e.g. via optional RS-232 interface).
Certifications and standards
The PLE-N complies with relevant international and European standards, including CE conformity in accordance with Machinery Directive 2006/42/EC and compliance with ISO standards for measurement accuracy. For certain models, factory calibration or DAkkS calibration is also possible, allowing them to be used in certified quality assurance systems.
Practical applications
Exact reproducibility is essential, especially in professional laboratory environments. This precision balance is used in:
-
Research laboratories and analytics: Precise weighing of chemicals (such as sodium chloride, nitric acid, pharmaceutical samples)
-
Educational institutions: Preparation and execution of experiments, e.g. in chemistry or biology laboratories
-
Industrial manufacturing: Checking production samples, quality control (e.g. when measuring solders, additives, powders)
-
Pharmacies and specialist shops: Preparation of prescriptions, dosing of minute quantities of active ingredients and excipients
Last but not least, the balance can be used for comparative measurements in the context of method validation and calibration work in external laboratories.
FAQs
How can the balance be cleaned?
Thanks to its chemical-resistant housing, it can be cleaned with standard laboratory cleaning agents. The weighing pan is removable, which facilitates hygienic cleaning.
Is the balance calibratable?
Certain models in the PLE-N series are available in a calibratable version. When purchasing, please pay attention to the desired option and the specific approval requirements.
What interfaces are available?
There is the option of retrofitting an RS-232 interface for data export to PC systems or LIMS - ideal for laboratory environments with digital workflows.
Can the balance be operated with different mains voltages?
The PLE-N can be used worldwide thanks to its wide-range power supply (100 to 240 V AC) and automatic voltage adjustment.
Can internal calibration weights be used?
Depending on the model, automatic or manual calibration with internal or external weights is possible. The operating instructions provide specific information on this.
