Ohaus EP612 digital scale has been discontinued and no longer in production. The replacement for the Ohaus EP612 is the Ohaus Pro EX2202 HERE. The information below is for reference only for those people that already own an Ohaus EP612 laboratory digital balance or looking to replace an precision scale.

Ohaus Explorer EP612 precision balance (610g x 0.01g) can be purchased 3 ways - the standard Explorer EP612 which has no internal calibration and is NOT Legal for Trade; the EP612N 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 EP612CN which is the EP612 with motorized internal calibration and IS Legal for Trade (check the box in the option section for Internal Calibration. The prefix "CN" designate Internal Calibration &Legal for Trade).

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 CPA2202 digital scale may be a better choice.

Another design issue with the Ohaus Explorer 0.01g and 0.1 toploading balances is the windshield surrounds the platform implemented to deflect air currents from disturbing the weighing pan. Notice how the windshield wraps around the weighing pan. Sometimes this causes an obstruction in your weighing application where the item you are weighing "you think is on the platform" but actually the sample is touching the windshield, thus providing the incorrect weighing results. The Sartorius CPA2202 precision balance and the Sartorius GW6202 doesn't have this windshield design. The Sartorius CPA2202 also offers a larger weigh pan 7.4" x 8.0" .

The EP612CN is NTEP Approved (a.k.a. Legal for Trade) and we highly recommend you click the Certificate of Conformance hyperlink below in the balance specification table to fully understand the Ohaus EP612CN limitations. The Ohaus EP612CN weighing specs are 610g weighing capacity and increments in 0.01 gram increments, but in the NTEP / Legal for Trade mode the increment is only in 0.1 gram graduations.

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.

Is the Ohaus EP612 too expensive for your budget and you can work with a little less weighing capacity? We also offer the Sartorius AY-612 (610g x 0.01g) priced substantially less than the Ohaus EP612.

Other 0.01gram resolutions digital scales we offer include the Sartorius AZ612, ED822, Myweigh i601 and iM01, AND Weighing EK-610i EJ610 and FX-1200i or the Scientech SL600.

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.

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.
