FHT 191 T 氚电离室
The FHT 191 T Ionization Chamber includes built-in memory for storing historical data. Its design facilitates both local and remote  monitoring applications.
By adding an air flow system to the Model FHT 191 N ionization chamber, the detector is converted into a tritium detector.  Ionisation currents down to a few fempto ampere (10-15 Ampere!) can be measured.  The integral microprocessor electronics calculate the activity concentration. 

Note: This detector system is also sensitive to gamma radiation and other gaseous isotopes (noble gases). Independent means are therefore necessary to differentiate between the gases being measured.

Measuring Range : 3 x 10^4 to 3 x 10^10 Bq/m^3
