Radiation Area monitoring systems

LUDLUM tritium monitoring systems feature ruggedised, flexible operation designed to be user-friendly. Easily Calibrated with 137Cs Gamma Range, LUDLUM’s tritium monitoring system detects tritium in air.  The tritium monitoring system is powered by rechargeable internal NiMH batteries and/or an external supply. It is available both portable and wall-mount. 

It features a maintenance-free diaphragm air pump to pull air through the 250 cc tritium chamber, and the air flow is measured internally with a mass-air flow sensor. A second 250 cc chamber is used to provide gamma compensation, allowing operation in higher gamma fields. 

Other internal sensors measure temperature and ambient pressure and provide compensation for these effects.
