Ohaus Explorer EP22001 high capacity balance (22000g x 0.1g) can be purchased 2 ways - the standard Explorer EP22001 which has no internal calibration; the EP22001C which is the EP22001 with motorized internal calibration (check the box in the option section for Internal Calibration. The prefix "C" designate Internal Calibration. None of the high capacity Ohaus Explorer balances 12kg and higher in capacity are Legal for Trade/NTEP Approved.

Although the EP22001 is targeted for this segment market along with applications in concrete, asphalt production, agriculture and quality control most of our customers purchase the Sartorius CPA34001S over the Ohaus EP22001 scale.
The reason typically for not selecting the Ohaus EP22001 is it only offers 2 year warranty, has a smaller 11" x 14" weighing platform and the real downfall with the EP22001 is the linearity is only ± 0.4 gram. Linearity is the accuracy of the balance and you review the definition for linearity here. The Sartorius CPA34001S has linearity specifications to ± 0.2 gram. Some people might say 0.2g verses 0.4g is twice the balance.
The Sartorius CPA34001S (34000g x 0.1g) offers a 3 year warranty, larger 11.7" x 15.6" weighing pan, IP-53 Rating so it is dust protected and also against "sprayed water", LCD display with adjustable backlight to see it in poorly lighted areas like mobile soil testing labs trailers on constructions sites and the linearity is ± 0.2 gram.
Many of the DOT Materials managers are buying the Sartorius CPA since it is made in the USA and they have federal funds requiring them to comply with the Buy American Act clause. FAR Part 25.003 requirements state that domestic end products are preferred over foreign end products, and the Ohaus Explorer is not made in USA.
