Common Accessories (Anaesthetic/fumigation/customized gas)
  • Gas Samplingtube(1m)
  • Shoulder Strap
  • Hand-aspirator
    (For TYPE A only)
Anaesthetic Accessories
  • Absorption Tube
  • Tube Fix Belt
Optional Accessories
  • Lithium Ion Battery Unit
  • Datalogging Software
  • AC Adaptor
  • FI-8000 needs Calibration only after every 1 year, Unlike Competitors, which requires calibration every 6 months. Time taken by Tritech for Calibration is only 1 day, this cannot be said about competitors.
  • FI-8000, same monitor can be used to monitor MBr & Ph3 (ALP) gases by change of setting by user himself. Competitor’s instrument monitors 1 gas only.
  • Riken FI-8000 uses long life & reliable interferometric sensor. Same as its previous model FI-21. These instruments have long life. ie more than 10-15 years. Depending on usage such long life and reliability is missing in competitors products.
  • FI-8000 has Rubber coated, tough enclosure which is ATEX approved and IP67 certified. Competitors offer plastic housing which are not approved.
