0-99%, non-condensing
Meets CE requirements (EN-61000-6-2/2001, 61000-6-4/2001)
(Twin and Single Rod probes must be used in metallic vessel or
stillwell to maintain CE requirement)
ΠSpecifications will degrade with Model 7xB, 7xD, and 7xP probes and/or fixed threshold configuration.
 Top 24 inches of Model 7xB probe: 1.2 inches (30 mm). Specification for top 48 inches of single rod will
be application dependent.
