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.
Standard Features Include:
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.
With stabilization times up to 50% faster and superior shock protection, Explorer delivers fast, accurate, and reliable results.

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 use of the touchless sensors on the base and display.
The automatic draftshield door model has 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 (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

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.
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.
