ΠEach Eclipse probe can be used for vacuum service (negative pressure) but only the Borosilicate
GWR probes (7xD/7xL) are suited for full vacuum conditions (Helium leak < 10^-8 cc/s @ 1 bar abs.)
 Eclipse is ideally suited to be used on foaming applications but in specific conditions where dense
foam can enter in the stilling well, coaxial GWR probes are not recommended.
Ž Depends on the spacer material. See model selection 7xD/7xL GWR probe.
ε  For media with r 1.9 to 10, GWR probe must be mounted between 3" and 6" (75 and 150 mm)
away from the metal tank wall or in a metal cage/stillwell.
