OHAUS precision balance Explorer Precision
This innovative laboratory balance is specially designed for professional users who require maximum precision, fast stabilization and maximum configurability. With its robust metal housing and a large, intuitive color touchscreen, it is an extremely reliable companion for a wide range of weighing tasks in the laboratory environment or in pharmaceutical, chemical and industrial applications. Sophisticated electronics ensure short response times and guarantee accurate recording of even the smallest mass values - ideal when a scale needs to deliver precise results at all times without compromising on ease of use and durability.
Performance features and benefits
Thanks to its advanced design, the scale is able to perform a wide range of measuring tasks. In addition to weighing in a wide variety of units, it is characterized by excellent repeatability and linear measuring accuracy. This model offers considerable advantages, particularly in demanding laboratory or production environments, thanks to its numerous intelligent functions:
- Touchscreen display (5.7"/145 mm) with VGA resolution: clearly structured display and simple user guidance
- Internal adjustment (AutoCal): Automatic calibration to ensure accurate results in changing environmental conditions (depending on model)
- Extensive weighing programs: Percent weighing, recipe, animal weighing, piece counting and more
- Robust construction: Sturdy metal and ABS composite, stainless steel pan and optional integrated draft shield (for mg models)
- Customizable user management: Four-level access concept, logged calibrations and GLP/GMP-compliant output functions
- Seamless data transfer: RS-232, USB and optional Ethernet interfaces
- Fast stabilization: value display in around one second (depending on model)
The combination of these features contributes to a significant increase in efficiency and minimizes the manual effort required for calibration and adjustment. At the same time, it offers extensive protective functions such as a lock against unauthorized adjustments and a non-editable log.
Certifications and standards
The Explorer series meets GLP and GMP requirements and is therefore suitable for regulated laboratory and production environments. Various variants also have EU approval, meaning they can also be used in areas subject to legal metrology
Typical fields of application
Thanks to their high-resolution sensors and solid construction, these precision scales cover a wide range of professional applications:
- Formulation applications in food production or the cosmetics industry, where exact quantities of various raw materials need to be weighed
- Quality control in laboratories to record samples before analysis and document them without errors
- Piece counting tasks in production or incoming goods, for example to accurately record components, tablets or pearls
- Animal weighing for smaller animals, for example in research or pharmaceutical facilities
- Checkweighing and percentage weighing, e.g. for fill quantity checks in production lines or batch processes
This scale is ideal for high-precision determinations of substances such as active ingredients, salts, fine powders or precious metals: the fast stabilization time means that routine weighings can be completed in a very short time. The robust design also enables use in slightly harsher environments without compromising accuracy.
Frequently asked questions (FAQ)
How often should the scale be calibrated?
Regular calibration is recommended, especially after changing location or if temperature fluctuations occur. On models with AutoCal, the scale does this partly automatically.
Is operation also possible for different user groups?
Yes. The device offers four-level user management with passwords. This allows those responsible to define separate access rights, for example for changing calibration options or creating reports.
Can I integrate the balance directly into my laboratory database?
With the existing RS-232 and USB interfaces, data acquisition is easy. In addition, an Ethernet interface is optionally available, which makes direct integration into network or LIMS systems (laboratory information and management systems) even easier.
Which weighing functions are available
The most important ones include simple weighing, piece counting, percentage weighing, recipe functions and dynamic weighing for unstable samples. This allows a wide range of routine and special tasks to be covered.
Is the balance protected against soiling?
The robust metal housing plus protective cover withstands common laboratory requirements. Spilled sample residues or splashes can be easily removed. A draft shield is included in the scope of delivery for mg models.
Can users customize the displays?
Yes, the menu system allows the backlight, display language and printer settings to be configured individually. In this way, the user interface can be optimally adapted to different processes.
Do I need special test weights?
As the device already has an internal calibration function (depending on the model), the need for external test weights is reduced. If you want to carry out an external calibration, E2 or F1 test weights are recommended to ensure precision.
Conclusion
With its high measuring accuracy, convenient touchscreen concept and automatic adjustment function (depending on the model), this balance is a versatile professional tool for laboratories, research facilities and industrial quality control. Users benefit from fast measurement processes, extensive documentation options and a solid design. This means that demanding weighing tasks can be carried out efficiently, reliably and reproducibly without compromising on flexibility, precision or durability.
