Sigma standard duals are comprised of a side-by-side wedge pair of "Loten." The standard dual, normally used in the manual mode, is capable of withstanding temperatures up to 350° F (by request), and can withstand an accumulated dose greater than 10 to the 8 RADS. However, SIGMA standard duals are also available in any of the other wedge materials.

In the past SIGMA duals were manufactured primarily from tempered lucite, SIGMA will continue to use lucite for those customers whose probes were qualified using lucite, until such time as they wish to requalify with the improved wedge material "loten".

To order please call SIGMA, or define the unit according to the "PART NUMBER GUIDELINE"
