The OHAUS Explorer Series of precision balances combine modern features and design elements to offer unmatched functionality in a line of high-performance balances unlike any other on the market

These smart and intuitive balances simplify even the most complex laboratory measurements.

  • Applications: Weighing, Parts Counting, Percent Weighing, Checkweighing, Animal/Dynamic Weighing, Filling, Totalization/Statistics, Formulation, Differential Weighing, Density Determination, Peak Hold, Ingredient Costing, Pipette Adjustment, SQC, Statistics
  • Display: 5.7" (145 mm) Full-color VGA graphic touchscreen display with user-controlled brightness
  • Operation: AC adapter (included)
  • Communication: RS232 and USB (included) or second RS232/Ethernet (accessories sold separately). GLP/GMP data output with real-time clock.
  • Construction: Modular design, metal base, ABS top housing, stainless steel pan, glass draft shield with top mounted side doors and flip/sliding top door (1mg models only),illuminated up-front level indicator, integral weigh below hook, security bracket, calibration lock, four touchless sensors, full housing in-use cover
  • Design Features: Selectable environmental filters, auto tare, user selectable span calibration points, software lockout and reset menu, user selectable communication settings and data print options, user definable project and user IDs, auto standby, up to 14 operating languages

A large color touchscreen gives access to the advanced application modes and icon-driven application software features such as user manager, library, and minimum weight indication.

Explorer features fast stabilization times, optimized linearity and repeatability specifications, enhanced vibration filtering, and the choice of traditional calibration or AutoCal™ models.

Explorer's sturdy modular design includes metal housing and a display that can be separated from the weighing base and tower- or wall-mounted for easy viewing in any workspace.

Equipped with a weighing cell that's precision-machined from a solid metal block, Explorer balances are extremely accurate and durable, and are ideal for laboratory and industrial environments.


Features such as four-level user management with password protection, and un-editable system log plus a high level of configurability make Explorer balances well suited for regulated applications.


A detachable terminal with a large color touchscreen, programmable IR sensors, and a frameless draftshield make Explorer precision balances easy and convenient to use.
