Ohaus EX12001 Datasheet

Explorer®

Analytical, Precision, and High Capacity Balances

Intelligent. Intuitive. Ingeniously Practical.

The OHAUS Explorer® Series has risen to the next level of ingenuity—expanding on its modern features
and design to offer unmatched functionality in a line of high-performance balances unlike any other
on the market.

Standard Features Include:

• Intelligent PERFORMANCE—All Explorers have newly optimized linearity and repeatability

specifications and enhanced vibration filtering for better balance stability. All models also come
standard with AutoCal™ automatic internal calibration. 3×3 filtering setup ensures fast and stable
weighing results. The Explorer EX…/E models additionally offer traditional external calibration.
These combined enhancements improve accuracy, efficiency, and throughput.

• Intuitive OPERATION—A large color touch-screen display, icon-driven application software

that features 14 unique application modes, and a 3 level adjustable angle display make
Explorer the easiest to use, most advanced balance in its class today.

• Ingenious DESIGN—The base and display separate for maximum flexibility in any work area.

Draftshield models isolate the weighing chamber to enhance stability and speed results while
offering maximum accessibility to the weighing chamber through top-mounted side doors
or through the versatile top door that flips or slides open. Hands-free entry is available with
optional automated side doors.

• Practical Features—Explorer has up to four user-programmable touchless sensors to minimize

cross contamination and wear and tear normally associated with repeated touching of the
balance. The OHAUS Explorer EX...N series of balances meet or exceed the Class I
or II accuracy requirements in accordance with NIST Handbook 44 and
Canada’s Weights and Measures Regulations.

options; access the weighing chamber by
flipping the top door or sliding the glass
panel open.

• The expansive side entry 6.3” × 9.4”
(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 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
—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.

* Analytical and precision models only.

Explorer® Analytical, Precision, High Capacity

Intelligent CALIBRATION

AutoCal™ ensures performance and assists with routine maintenance
by automatically calibrating the balance daily.

• Self-calibrates the system when it senses a temperature change
sufficient enough to affect weighing accuracy, or every 11 hours

• Performs routine calibration and reduces the need for external
masses

• External Calibration Models Available —
Select models feature traditional external calibration in which
external weights (user’s choice of calibration weight values) are
required to calibrate the balance to ensure accuracy

Explorer is the industry’s most easy-to-use balance, featuring leveling
assistance and instructional messaging for quick out-of-the-box
setup and use.

• Easy to view illuminated level indicator placed at the front of
the balance

• Adjustable thumbwheels are easy to turn to level the balance

• Level assist screen helps users quickly identify which

thumbwheels need to be adjusted to level the balance

• Data Transfer Function helps to output data directly into
Microsoft Excel

• Instructional messaging during application use guides users
through the weighing process

• User information menu allows users quickly view and learn more
about the available balances features

• Up to 13 operating languages make Explorer’s Intuitive User
Setup truly universal

Capture and store highest weight
in a series. Both stable and unstable
weights are captured.

Parts Counting

Count samples of uniform weight.
Choose Standard Counting, Check
Counting, or Fill Counting.

Pipette Adjustment
