Intuitive SOFTWARE

SmarText™ 2.0 is OHAUS easy-to-use graphical software featuring 14 applications, virtual QWERTY and numeric keypads, and below minimum weight indication.
• Color VGA display with icons for simple menu navigation
—High resolution, 5.7” (145mm) diagonal color 640 × 480 pixel display reproduces highly readable operating software
—Resistive touch screen display quickly responds to the operator’s touch or stylus
• 14 built-in applications with customization capabilities to meet the varying needs in laboratory and industrial settings
• Minimum Weight capability with visual warning feature
• Virtual QWERTY keyboard and numeric keypad to quickly input GLP and GMP data and other application data, a direct scan of the sample ID to the input field with an optional barcode reader.
• Password protected User Manager with administrator capability
• Library function to store and recall customized applications including 10 recipes for Formulation application.
• Alternate RS232 command feature adapts the balance to existing data acquisition software
• External input for zero, tare or print operations via the external foot switch accessory
• Audible and visual feedback for touch screen input commands as well as the indication of the check weighing status


Explorer’s 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. It helps to eliminate sample residue transfer and contaminations.
• Side doors seamlessly glide on top-mounted bearings
• 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 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



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.


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 3-11 hours, depending on the user configuration
• 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
