MARC 5000 Tritium Bubbler
Dual-pot atmospheric tritium sampler (without oven) for collecting tritium in its water vapour form (HTO) at nuclear facilities.
An inlet paper pre-filter (Ø 45 mm) prevents dust intake, and the electronic flow meter is protected by Gore-Tex filters. The tritium activity in the collected sample is measured daily, weekly or monthly with a liquid scintillation counter and related to the sampled air volume.
- Collects tritium in its water vapour form (HTO) on stacks, hoods or in the environment
- Optional cooling system reduces evaporation and allows weekly collection
- Automatic regulation of the air flow according to the pressure drop
- Simultaneous dynamic sealing device for both bottles, with easy opening and closing
- Fixed installation, chimney connector or mobile trolley
