Heavy Water Sniffer System

System is used for monitoring presence of heavy

water (D2O) vapour in air.

IR rays are passed through a flow cell containing

Air sample, IR rays are absorbed depending on

D2O concentration in air

We get PPM concentration of heavy water

Heavy Water Loss Monitoring System

• D2O concentration is based on IR

absorption principle

• Air from ventilation duct passes through

an optical unit which processes and

gives D2O conc. in PPMv.

• Online system , provides Heavy water

loss Concentration, D2O loss rate and

cumulative loss
