Ingeniously striking a balance between cutting-edge technology and functional design, the Explorer delivers accurate performance, that will improve your efficiency in the lab.

Ohaus EX423 milligram balance has a touchscreen weigh indicator that will really wow you. This is the most advanced design features yet to come from Ohaus. 420 gram weighing capacity and 1 milligram readability this digital balance is a beautiful weighing instrument that cannot be passed up. Brand new and designed to optimize form and function, improving weighing efficiency while delivering an easy to read display.

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. 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 an adjustable angle display make Explorer the easiest to use, most advanced balance in its class today.

Ingenious Design: The base and terminal separate for maximum flexibility in any work area. The design also isolates the weighing chamber to enhance stability and speed results. Draftshield models feature an oversized chamber with a new quick remove design, enhanced with a unique anti static system.

Practical Features: Explorer has four user-programmable touch free sensors to minimize cross contamination and button wear.

Intelligent PERFORMANCE - Explorer delivers accurate results within seconds, improving operator efficiency, productivity and throughput, with a stabilization time up to 50% faster. Fast stabilization time improves operational efficiency, increases throughput, and improves productivity. Optimized linearity and repeatability specifications provide accurate and repetitive results. Superior vibration filtering provides balance stability in unstable environments.

Intuitive SOFTWARE - SmarText™ 2.0 is OHAUS' easy-to-use graphical software featuring 14 applications, QWERTY and numeric keypads, and below-minimum weight indication. Color VGA display with icons for simple menu navigation. High resolution, 5.7 in (145 mm) color TFT display reproduces the highly readable operating software. Resistive touch screen display quickly responds to operator's touch or stylus. Fourteen built-in applications with customized capabilities to meet the varying needs in laboratory and industrial settings. Explorer also has a ,minimum weight capability with a visual warning feature and a QWERTY keyboard and numeric keypad to quickly input GLP and GMP data and other application data. User Manager with administrator capability and library function to store and recall customized applications comes standard. Alternate RS232 command feature adapts the balance to existing data acquisition software. External input for zero, tare or print operations are available via the external foot switch accessory. There is also audible and visual feedback for button presses as well as the indication of the check weighing status.

Ingenious DRAFTSHIELD - Explorer's draftshield provides ample access and visibility to the weighing chamber and features antistatic coated glass. Frameless, flip-top design provides unobstructed access to the weighing chamber. The expansive side entry 6.3 x 9.4 in (160mm x 240mm) 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 that could adversely affect the weighing results. Side doors seamlessly glide on top-mounted bearings, helping to prevent any potential bind up when balance is left uncleaned. 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 four touchless sensors for hands-free operation of print, calibration, tare, and others. 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. Two sensors on the base and two on the display can be set up individually to allow for remote operations.

Intelligent Calibration - AutoCal™ ensures performance and assists with routine maintenance by automatically calibrating the balance daily. Fully-automatic internal calibration system means no need for external masses and eliminates cost to maintain external weights. Explorer self-calibrates the system when it senses a temperature change sufficient enough to affect weighing accuracy, or every 11 hours.

Intuitive User Setup - 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 and adjustable, easy to turn, thumb wheels and level assist screen help users to quickly identify which thumb wheels 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 to quickly view and learn more about the available balances features. Up to 11 operating languages make Explorer's Intuitive User Setup truly universal.
