Ohaus EP114 has been discontinued and no longer in production. The replacement for the Ohaus EP114 is the Ohaus Explorer Pro EX124. Additional alternatives would be the Ohaus Adventurer AX124, Ohaus EX124, Mettler Toledo JS703C/A, A&D GH-120 or the new Sartorius ENTRIS124i-1S, Sartorius Quintix 124-1S or Sartorius Secura 124-1S. The information below is for reference only for those people that already own an Ohaus EP64 or looking to replace an analytical balance.

You can buy an Ohaus Explorer EP114 analytical balance 3 ways - the standard Explorer EP114 which has no internal calibration and is NOT Legal for Trade; the EP114N which IS Legal for Trade with no internal calibration (check the box in the option section for Legal for Trade). The prefix "N" designate Legal for Trade); the EP114CN which is the EP114 with motorized internal calibration and IS Legal for Trade (check the box in the option section for Internal Calibration). "CN" designate Internal Calibration & Legal for Trade.

Ohaus Explorer EP114 (110g x 0.1mg) features an integrated draft shield enclosure. The enclosure is required due to the extreme sensitivity. Merely waving your hand slowly over the weighing platform with result in air turbulence getting under the weighing pans and causes erratic readings.

In some applications when the balance is placed in a glove box or you are weighing objects larger than the door opening of the draftshield you can run into problems. An example might be weighing an 8-inch silicon wafer to determine a coating applied - you just can't get the wafer in the fixed draft shield. In this situation an analytical balance with the glass draftshield removed would be operated in a larger enclosure, again to minimize air turbulence.

If you foresee needing to operate the analytical balance without the glass enclosure we recommend you review either the Scientech ZSA120 or Sartorius CPA124S analytical balance since these balances offer a removable glass draftshield. Another benefit with a removable glass draftshield is easy of cleaning the balance.

Additional the Scientech ZSA features an all glass draftshield design for optimal illumination while the Ohaus Explorer has 3 sides of glass.

One design issue you should be aware of with the Explorer and Voyager Series outfitted with internal calibration when the balance is used in the non-NTEP mode is the inability to disable the use of internal calibration. The Ohaus line is the only balance we know of that does not allow you to disable the internal calibration. Where this becomes an issue is most calibration A2LA Certification Calibration companies will NOT calibrate a balance unless the internal calibration can be disengaged. If your balance is going to require A2LA Certification the Sartorius analytical balance may be a better choice.

Ohaus Explorer Pro Balances are available in both analytical and precision configurations, in a variety of capacities. The Explorer Pro line of precision balances offers capacities ranging from 210 x 0.001 grams to 32,000 x 0.1 grams. The analytical balances line offers capacities of 62, 110 and 210 grams and you can review them all at the bottom of this web page.

Before purchasing any analytical balance, be sure you review the Sartorius GD503. Nothing compares in price, quality, and value. We keep the GD503 (100g x 0.1mg) in stock and ready for immediate delivery. Only GD503 analytical balance offers legal for trade, RS232 interface, 3 year limited manufacturer's warranty, and even includes 100 gram external calibration weight. In addition to these great features, we even have an exclusive offer allowing you to purchase a Sartorius data printer or WinWedge Software at a special discount price when you buy a Sartorius GD503 analytical balance.

We understand purchasing an analytical balance is a major capital expense and if you have any questions give us a call and one of our weighing experts can discuss your weighing application and get you the most affordable balance for your weighing needs.

Explorer Pro Analytical Models
The Explorer Pro Series features 4 analytical models with capacities up to 210g and 0.1mg readability for maximum accuracy.  The new draftshield design and contoured fit provide optimum draft protection from wind currents for superior balance stability and reproducibility in challenging environments such as high traffic areas.  Explorer Pro is perfect for university research, teaching laboratories and general lab applications.
high precision balance
The spirit bubble indicator is located on the front of the balance so you can always verify your lab balance is level.  Balances must always be level to correctly transfer the force applied to the weighing balance parallel to the weigh cell. If the balance is off-centered (not level) this generates a counterforce to the suspension guides of the weigh cell resulting in inaccurate or distorted weighing results.
Application Modes
  • Percent Weighing:
    allows you to place a reference load on the pan, and check other samples as a percent of the reference load.  Each new sample will be a "percentage" of the original reference, the display shows the variance in – or + percent of the reference.
  • Gross/Net/Tare:
    is an application mode commonly used when you need to identify the individual weights of the container, the material and both together.  The container weight is the Tare weight, the material is called the Net weight and the container and material together are called the Gross weight.  The Net weight is displayed on the readout.
  • Weighing:
    Basic weighing with primary and secondary weighing units, time, date and capacity bar.
  • Dynamic / Animal Weighing:
    Dynamic weighing allows the user to weigh unstable matter that may be moving. This mode can be set to manual, semi-automatic, or automatic; the displayed data includes filtered weight and unfiltered weight.  Displayed data also includes filter level, capacity bar graph and operation mode (manual, semi or auto).
  • Parts Counting:
    Enhanced parts counting features include auto sample optimization, user definable sample size and manual entry using scroll keys.  The "Parts Counting Check" feature allows for quickly checking a sample of pieces against a preset criteria, with results displayed as the number of pieces.  The "Parts Counting Fill" feature allows for quickly checking a sample of pieces against an established criteria, with results displayed as a percentage of the preset target.
  • Filling:
    Filling permits the user to preset a target reference weight, then add material to the balance to meet the target weight.  The display shows the preset target weight and the percentage of the target by monitoring the differential data, the fill bar is split in two sections for fast filling up to 90%, then slower accurate fill to reach target (100%) weight.
  • Checkweighing:
    is used when items need to be checked against a preset target, after the target weight is set, and over/under parameters are established.  Checkweighing is measured as a factor of over the target, under the target, or accept.  The display automatically shows the difference in percent and weight.
Optional Accessories
The Explorer Pro Series offers a complete line of accessories and masses to expand your mass measurement capabilities, including: Density determination kit (for 0.1mg and 1mg balances), modular display upgrade kit (for balances up to 8kg), model SF42 42-column impact printer, auxiliary table display, remote table displays, security devices, RS232 cables, TAL Software WinWedge V1.2, calibration masses. underhook weighing

Industry Leading Quality and Support
All Ohaus Explorer® Pro balances are manufactured under an ISO 9001:2000 Registered Quality Management System. Our rugged construction and stringent quality control have been hallmarks of all Ohaus products for nearly a century.

voyager balance
Shown above is an image of a Voyager Analytical Balance (the Explorer Analytical Balance looks similar) with OPTIONAL 470007-010 Density Determination Kit
Four methods of density determinations can be made with the Voyager Pro balance.
The Four Methods of Density Determination:
  1. Solids more dense than water
  2. Solids less dense than water
  3. Liquid density
  4. Porous material (impregnated with oil).
specific gravity scale
An accessory density determination kit is designed to be used with Ohaus Explorer Pro balances.  A built-in reference density table for water at temperatures between 10°C and 30°C is included in the balance software.  When making density measurements, the material should weigh at least 10.0 mg on an analytical balance and 100 mg on a precision balance.
