Ohaus EP64 has been discontinued and no longer in production. The replacement for the Ohaus EP64 is the Ohaus Pro EX124 HERE. 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 EP64 (62g x 1mg) analytical balance 3 ways - the standard Explorer EP64 which has no internal calibration and is NOT Legal for Trade; the EP64N 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 EP64CN which is the EP64 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).

Ohaus Explorer EP64 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 ZSA80 or Sartorius CPA64 analytical balance since these balances offer a removable glass draftshield. Another benefit with a removable glass draftshield is easy of cleaning the balance.

Additional both the Scientech ZSA and Sartorius CPA feature 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 CPA64 Analytical 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.

Looking for greater weighing capacity for an analytical balance? We have another great buy - see the CPA324S which offers a whopping 320g x 0.1mg and in stock for immediate shipping. When you purchase the Sartorius CPA324S you can select from a free Sartorius YDP20-OCE Printer valued at $1050 or Winwedge Software.
