Ohaus Explorer Semi-Micro Balances

Ohaus Explorer Semi-Micro Balance range is designed to ensure accurate weighing results with 0.01mg readability and up to 220g capacity. The Explorer is a smart intuitive balance that simplifies even the most complex laboratory measurements using its intelligent features. Using modern features and design elements Ohaus Explorer Semi-Micro balances offer you a high-performance balance unlike any other on the market.

Ohaus Explorers provide an extremely modern user experience with its intuitive SmarText™ 2.0 software. Having an icon-based touchscreen display, advanced applications, a USB host port, and a memory library make the user have an easy experience with the balance. The Ohaus Explorer also has touchless sensors, an ionizer, and automatic draft shield doors to ensure the integrity of its results.

Customise user management

Safeguard quality and conformity

The built-in ionizer, included in Explorer automatic door models, generates bipolar ions continuously from positive and negative discharge electrodes and directs the ionized air onto the charged body to eliminate static electricity. These charges can build up in the weighing chamber and alter weighing results by as much as several milligrams.

The automatic door feature, available on certain models, allows access to the weighing chamber without the need to touch the draft shield door. Placement of samples is achieved in one swift motion, eliminating the repetition of picking up and putting down samples due to a lack of free hands. The automatic doors are also more than a user-friendly feature; they minimize vibrations caused by manual operation that can affect weighing results.

Ohaus’ signature AutoCal™ internal calibration system ensures the balance is always ready for use and eliminates the need for manual routine calibration. Explorer’s internal calibration mechanism uses multiple weights and adjusts the balance at several points within the weighing range; this results in lower measurement uncertainty than a simple span calibration. Additionally, Explorer balances feature a built-in Repeatability Test, which helps evaluate the balance’s performance and aids in determining a suitable minimum weight for applications requiring high accuracy.

* D stands for dual range, i.e. the capacity of fine range is 52g and the maximum capacity is 120g.
** According to USP41, repeatability is satisfactory if two times the standard deviation of the weighted value divided by the minimum weight does not exceed 0.10%. The standard deviation obtained is less than 0.41d, where d is the scale internal, replace this standard deviation with 0.41d. In this case, the repeatability is satisfactory if 2*0.41d divide by minimum weight is less than 0.10%.
