OHAUS Explorer Analytical analytical balance
The laboratory balance presented here is tailored to demanding analysis and research tasks and offers high-precision weighing results down to the 0.1 mg range. Compared to many conventional devices, it impresses with its intelligent combination of robust design, automatic adjustment and a user-friendly color touchscreen. With customizable communication options and multiple operating modes, this model is ideal for laboratories, industrial sites, pharmaceutical companies or research facilities that require accurate readings with maximum efficiency.
Innovative technology and precise measurement performance
Thanks to a measuring system made of solid metal, this series is designed for long-term stability. The detachable terminal allows flexible placement and minimizes vibration or interference during delicate weighing processes. A color 5.7-inch VGA touchscreen, paired with sensor-operated doors (certain variants only), reduces the risk of touch measurement errors. In addition, the proven AutoCal system enables automatic adjustment, ensuring accurate results even in daily use.
Important key technical data in a clear format:
- Max. Weighing range: models up to 320 g
- Readability: 0.1 mg
- Stabilization: between 2 and 3 seconds depending on the model
- Automatic door function: integrated in the models with the "AD" suffix
- Internal adjustment: AutoCal - automatic adjustment
- Display: Illuminated touchscreen display (145 mm) with adjustable brightness
- Construction: Robust metal housing, stainless steel shell and glass-encased draft shield
Some variants are equipped with EU approval (certified for 1 mg readability) and bear the abbreviation "M". This approval makes it easier to work under regulated conditions. In addition, all models offer an RS232 and USB interface as standard; an Ethernet interface is available as an option. An integrated underfloor hook allows weighing due to density determinations or bulky samples. Various units of measurement such as grams, milligrams, carats, pounds or newtons can be set for laboratory environments that require different units.
The software supports a wide range of weighing functions: Piece counting, percentage comparison, statistical evaluations, recipe management, dynamic weighing, pipette adjustment or density determination. This significantly simplifies complex processes in the laboratory. Special SQC functions and user management with password protection also open up application possibilities in sensitive areas where traceable documentation is required.
Certifications and standards
For rooms with strictly regulated processes, the "M" models (e.g. EX224M or EX324M) offer EU approval. This allows for legal-for-trade use, for example in quality control or in officially monitored facilities. Regardless of the model, the balance can also be easily integrated into a GMP- or GLP-compliant system, as it ensures complete documentation including data output with a real-time clock.
Application examples
- Quality control in the pharmaceutical industry: For high-precision weighing of active ingredients or excipients that require exact dosing in compliance with strict regulations.
- Formulation of recipes in the chemical industry: Thanks to the formulation and summing functions, sensitive substances such as color pigments, catalysts or powders can be mixed precisely.
- Food analysis: The draft shield with top-mounted doors ensures a clean working environment for fat or protein determinations and when weighing sensitive ingredients.
- Research and development in universities: In addition to basic laboratory analyses, the balance also enables the determination of density or peak hold values, which is extremely useful in research projects in particular.
FAQs
How often is calibration required
The AutoCal system performs the adjustment automatically at certain intervals. Nevertheless, it is advisable to carry out a check measurement before starting the program in the event of a change of environment or large temperature fluctuations.
What are the advantages of the automatic door function?
Contactless operation prevents vibrations or draughts from distorting measurements. At the same time, users save time as the doors open and close automatically (only on "AD models").
What is the minimum weight and what is it relevant for?
The typical minimum weight according to USP of 0.16 g means that measurement fluctuations below this value could lead to imprecise results. This is relevant for challenging applications where maximum accuracy is required.
Which interfaces are suitable for data transmission?
An RS232 and USB interface are available as standard. An Ethernet interface can be added as an option, which enables convenient integration into laboratory management systems in modern laboratory environments.
Can the balance be used in a clean room or in high humidity conditions?
The device works reliably at up to 85% relative humidity and temperatures from -10 °C to 30 °C. For use in cleanrooms, the applicable specifications and cleanroom classes should always be taken into account.
Conclusion
This model offers a sophisticated combination of maximum measuring accuracy, intuitive operation and flexible configuration options. Thanks to the wide range of models - from standard versions to legal-for-trade versions - these laboratory balances can be adapted to a variety of requirements in the analytical sector. Users benefit from stable weighing results, powerful software functions and a robust design that easily copes with intensive everyday use in industry and research. Together with the optional automatic door function and the extended documentation options, weighing in the laboratory becomes a precise and efficient process. The OHAUS Explorer Analytical analytical balance therefore impresses with its first-class performance, reliable documentation and future-proof technologies.
