Ohaus Explorer Analytical Balances

The Ohaus Explorer Analytical balances use modern features and design elements to offer you a high-performance balance unlike any other on the market. The Explorer is a smart intuitive balance that simplifies even the most complex laboratory measurements using its intelligent features. The large colour touchscreen allows a user to access the advanced application modes and icon-driven application software features e.g. user manager, minimum weight indication, and library.

Ohaus Explorer Analytical draft shield provides easy entry to the weighing chamber using a flip or sliding top door and the top-mounted side doors that can be automatically controlled on certain models. The Ohaus Explorer features a hands-free operation to improve weighing efficiency, minimise contamination, and eliminate sample residue transfer.

Enhanced performance and value with the latest EX2.20 software update

The EX2.20 software update provides additional functionality aimed at simplifying and helping to achieve compliance in regulated applications and environments. Ohaus Explorer Analytical’s advanced applications simplify even the most complex laboratory measurements. Whether it’s determining the difference between initial and residual weights or calculating the density of solids and liquids, Explorer eliminates the need for time-consuming manual calculations and data logging. The high-resolution display and innovative user interface make balance setup and application use effortless.

Enhance data integrity and transparency

  • Record changes to balance settings, calibration adjustments and printed results, user-access data, and GMP/ GLP data fields
  • Log 5000 records, export PDF log, and save to a USB flash drive.

Customise user management

Safeguard quality and conformity

Draft shield

Ohaus Explorer Analytical draftshield provides ample access and visibility to the weighing chamber through the versatile top door and side sliding doors. Select models feature motorized side doors that open and close automatically with the use of the touchless sensors on the base and display. The automatic draftshield door models have a new function for automatically opening draftshield doors without touching the balance, which helps to eliminate sample residue transfer and contaminations.

The versatile top door offers two entry options; access the weighing chamber by flipping the top door or sliding the glass panel open.
The expansive side entry 160 mm × 240 mm allows you to freely place and remove large weigh boats or other large vessels in the weighing chamber. Antistatic coated glass helps dissipate static charges in the weighing chamber which could adversely affect the weighing results. Easy to install and remove glass panels and a stainless steel bottom make Explorer extremely easy to clean. A draftshield chamber light is available when the balance is used in low lighting environments.

Practical Touchless Sensors

Explorer Analytical features up to four touchless sensors for hands-free operation of zero, print, calibration, tare, automated draftshield doors and other selectable functions. Hands-free operation improves weighing efficiency, eliminates sample residue transfer and minimizes contamination.

Two sensors on the base and two on the display can be set up individually to allow for remote operations. The sensors can be set up to provide automated operation of the draftshield side doors and can be programmed to automatically open the opposite side door in order to support efficient and logical sample placement with your free hand.

Application Software

Ohaus Explorer Analytical ’s advanced applications simplify even the most complex laboratory measurements. Whether it’s determining the difference between initial and residual weights or calculating the density of solids and liquids, Explorer eliminates the need for time-consuming manual calculations and data logging. The high-resolution display and innovative user interface make balance setup and application use effortless.
