Excalibur Lab

Ideally suited for laboratory transmission measurements where nominal pressures and temperatures do not dictate the need for specialized o-ring seals. The optical material of all laboratory probes is quartz glass. The Hellma Excalibur Lab probe is a classic transmission probe for use in laboratories or for online measurements. 


Special Features

  • Highest precision due to the monolithic quartz measuring head
  • Optical protection of the measuring head while minimizing stray light due to removable protective sleeve
  • Use of FFPM (perfluoroelastomer) O-rings with high chemical resistance
