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

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.

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

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.


Ohaus EXPLORER Laboratory Balances

Intelligent Performance
Explorer delivers accurate results within seconds. When coupled with optimized Linearity and Repeatability and superior span & zero drift. Specifications operator efficiency, productivity and throughput are ensured.

Intuitive Software
SmarText 2.0 is OHAUS’ easy to use graphical multi-language software featuring 13 applications, qwerty and numeric keypads and below-minimum weight indication. Communications port connections including standard RS232, USB and optional 3rd communication port slot (Ethernet).

Ingenious Modular Design
Explorer’s modular design features a color touch-screen VGA display that can be separated from the weighing base and mounted remotely, on the wall or on an optional tower accessory.

Practical Touchless Sensors
Explorer features four practical, touchless sensors for hand-free operation of print, calibration, tare and other selectable functions.

Intelligent Calibration
AutoCal™ ensures performance and assists with routine maintenance by automatically calibrating the balance daily and when it detects a 1.5°C change in temperature. It can also be set to calibrate at a user-defined interval.

Ingenious Draftshield
The draftshield provides ample access and visibility to the weighing chamber with removable, frameless doors constructed of antistatic coated glass. The doors are track mounted with sealed bearings for a smooth and efficient gliding action.
