Model 606-651652 – Portable Tritium in Air Discriminating Monitor

Portable Tritium in Air Discriminating Monitor

Model: 606-651652

Applications

The 606-651652, Sensetecz Portable Tritium in Air Discriminating Monitor,  combines a 606 unit – Sensetecz Tritium in Air Monitor and a 651652 assembly – Sensetecz Dryer & Catalytic Converter Assembly.

606-651652 has all characteristics of 606. Please refer to the 606 datasheet. 

Meanwhile 606-651652 has following extra functions:

• Tritium water and pure elemental tritium readings can be provided

In 606-651652, 651652 is a Dryer & Catalytic Converter Assembly, which is installed between the outlet of the 606-measuring chamber and the inlet of 606-compensation chamber. Using this assembly, the readings of tritium vapor and pure elemental tritium ³H₂ can be provided.

Overall, within 0°C to 50°C, 606-651652 can provide reliable readings of active levels of Total Tritium (tritium gas+ tritium vapor) in air, HTO Tritium Vapor,Pure Elemental Tritium ³H₂, from 1µci/m³ to 200,000µCi/m³ with full range noble gas compensation and full range gamma compensation. Meanwhile, it can provide gamma activity level readings up to 10R/hr.
