Ohaus®  -  Explorer® Series Analytical Balances

• 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 Explorer EX…M Models have been designed and verified to meet or exceed the Class I and II accuracy requirements in accordance with EC Directives and EN45501.

• The expansive side entry (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 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.

Intelligent CALIBRATION

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

• Fully-automatic internal calibration system
• No need for external masses
• Eliminates cost to maintain external weights
• Self-calibrates the system when it senses a temperature change sufficient enough to affect weighing accuracy, or every 11 hours
• External Calibration Models Available
  • Select precision models feature traditional external calibration in which external weights (user’s choice of calibration weight values) are used to calibrate the balance to ensure accuracy

OHAUS EXPLORER® Application Software

The OHAUS Explorer’s advanced applications simplify even the most complex laboratory measurements. Whether it’s determining the difference between initial and residual weights or calculating the density of solids and liquids, Explorer eliminates the need for time consuming manual calculations and data logging. The high resolution display and innovative user interface make balance setup and application use effortless.

Standard Apps

• Weighing Determine weight of items in the selected unit of measure. Minimum Weight feature is also available.
• Percent Weighing Measure the weight of a sample displayed as a percentage of a pre-established Reference Weight.
• Dynamic Weighing Weigh an unstable load. Balance takes an average of weights over a time period.
• Totalization Measure cumulative weight of multiple items. Cumulative total may exceed balance capacity.
• Differential Weighing Store sample weights and calculate the difference between initial weights.
• Peak Hold 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 Check pipette values by weight analysis, with built-in water density table. (Non High Capacity Models)
• Check Weighing Compare the weight of a sample against target limits. Choose from Standard, Nominal-weight, or Nominal-Percent.
• Filling Fill a container to a target weight. Progress bar displays filling status.
• Formulation For compounding and recipe making. The number of components can be from two to 99.
• Density Determination Determine density of solids more dense than water, solids less dense than water, liquids, or porous material.
• Ingredient Costing Determine cost of formula or recipe based on known cost/quantity of components or ingredients.
• SQC Monitor and/or control processes to eliminate under and over filling. make balance setup and application use effortless.
