OHAUS precision balance Explorer Precision
The OHAUS precision balances in the Explorer series are specially designed for demanding weighing tasks in laboratory and industrial environments. With their robust design, a sophisticated load cell and an intuitive colour touchscreen, these laboratory balances offer precision at the highest level. They are ideal for applications such as recipe preparation, piece counting or checkweighing and are particularly easy to use thanks to their intelligent functions. Compared to comparable precision balances on the market, they score points with extensive configuration options and innovative technologies such as automatic calibration (AutoCal) to ensure accurate and reliable measured values at all times.
Versatile features for demanding applications
The series includes various models with maximum loads ranging from a few grams to over ten kilograms. Particularly noteworthy are the four non-contact sensors and the AutoCal mechanism integrated in many models. This means that the scales adjust themselves automatically depending on temperature or time intervals without the need for manual intervention. For hygienically sensitive areas or pharmaceutical applications, the scales fulfil important GLP/GMP criteria, as they can automatically log the weighing results including a time stamp. Extensive interfaces are also available for data communication:
- USB port (included as standard)
- RS-232 interface ( included as standard )
- Ethernet port (optionally available as an accessory)
- Second display (optional for flexible use)
The large 5.7-inch VGA touch display ensures convenient user guidance, while features such as lighting, language selection and parameterisable measuring range adjustment make day-to-day work considerably easier. The detachable terminal, which can be positioned flexibly depending on space requirements, also increases ease of use.
With stabilisation times of just one second, measurements can be carried out quickly and reliably. In addition, each model has a robust metal or ABS construction with a stainless steel shell that is easy to clean. The versions with low readability (e.g. 1 mg) already have an integrated draft shield to minimise disruptive air currents. The larger version (readability from 0.01 g) is equipped without a draft shield, but allows convenient weighing of larger samples. All versions also include a labour protection cover and are therefore particularly durable.
In a regulated environment, the M versions of the scales (e.g. EX423M, EX10202M) are verified models with EU approval. This means that these devices comply with strict custody transfer regulations and provide legally compliant measurement data when official tests are required, for example. For particularly sensitive measurement processes, a four-level user management system is also implemented, which documents all activities using a password and system log.Certifications and standards
Many Explorer Precision models support EU approval and fulfil GLP/GMP-relevant documentation requirements. They are also equipped with CE safety testing. The robust metal components and high-quality manufacturing also fulfil industry standards for laboratory equipment.
Concrete application examples
- Quality control in the pharmaceutical industry: thanks to dynamic weighing, the scale can be used to analyse the moisture and weight of small tablets or capsules
.
- Formulation creation in chemical laboratories: Thanks to the automatic tare functions and piece counting, each ingredient can be precisely dosed, for example for powders or solvents.
- Food analysis: Ingredients or samples in food processing are precisely portioned in checkweighing mode.
- Research and development: The high repeatability and minimal weighing deviation are suitable for mixing and analysing sensitive samples, for example in materials research.
FAQ
How is calibration carried out
?
Most models have AutoCal, an automatic adjustment function. They can also be adjusted externally if the model is equipped with an adjustment lock.
Which communication interfaces are available
USB and RS-232 are included as standard. An Ethernet connection is available as an accessory so that the scales can also be integrated into a network.
Can a draft shield be retrofitted?
The draft shield is already integrated in the mg models, while other models do without it in favour of a larger weighing surface. Separate retrofitting is not necessary as the series is designed accordingly.
Are the scales suitable for legal-for-trade applications?
The models with "M" (e.g. EX423M) are of interest for legal-for-trade applications. These have EU approval and can be used in official areas or in retail.
Summary
These precise laboratory balances combine fast stabilisation, a wide range of communication options and particularly intuitive operation. Thanks to their robust design and automatic calibration, they achieve a high level of reliability even in demanding environments. Users benefit from extensive functions for piece counting, weighing in per cent, recipes and much more. This makes the OHAUS Explorer Precision precision scale a future-proof choice for laboratories, quality assurance and production thanks to its intelligent data acquisition and first-class user-friendliness.
