EXCALIBUR IMMERSION PROBE
ALL-QUARTZ-PROBES

 alt  
These Hellma Analytics All-Quartz-Probes are outstanding due to their unique design which makes additional sealing material superfluous. This makes them the ideal device for measuring aggressive samples even at lowest temperatures - measuring beyond the limits.

  • All parts in contact with sample made of high-purity quartz
  • High chemical resistance against aggressive acids and samples
  • Monolithic measuring head made of SUPRASIL®300 liquid-tight fused into a quartz barrel
  • Steady optical path length even at high temperature variation
  • Applicable at temperatures down to -180 °C due to up-grading with vacuum jack
  • Provides useability in applications where conventional probes fail

EXCALIBUR STANDARD IMMERSION PROBE
ALL QUARTZ-PROBE

Tapered version with ground glass joint NS 19/35

alt  
These all-quartz-probes have a monolithic probe head made of quartz glass SUPRASIL® 300 liquid tight fused into a quartz barrel. By using a total reflection prism, the light beam passes through the sample only once, as with a cuvette measurement.

  • High chemical resistance against aggressive acids and samples
  • Monolithic measuring head made of SUPRASIL®300 liquid-tight fused into a quartz barrel

EXCALIBUR IMMERSION PROBE
ALL-ROUND PROBE

alt  

This classic transmission probe features a broad range of possible applications. Whether for use in the lab, for online monitoring in process environment or even for TDA-measurements - it is always the right choice.

All-round, in the lab, or process environment.

  • Best possible protection of the measuring head and minimizing of stray light at the same time due to protective sleeve
  • Ergonomically designed handle for ideal grip
  • Use of FFKM (perfluorelastomer) O-rings with increased chemical resistance
