An ideal instrument for workplace environmental monitoring, the FHT 1659 L is applied for the continuous monitoring of aerosol bound artificial beta activity in air. Measurement of aerosols is made possible by a detector assembly that includes a leak-proof aerosol filter and a sealed counter tube with lead shielding.
Product Detail
The FHT 1659 L is applied for the continuous monitoring of aerosol bound artificial beta activity in air. The activity of aerosols accumulated on a fixed filter as well as the derived activity concentration are measured and controlled.
Mobile application for workplace monitoring in controlled areas
CAM algorithm for the continuous evaluation of the artificial beta activity concentration in physical units of Bq/m3
Dynamic compensation of varying levels of natural radioactivity in air (Rn-progeny)
Freely selectable alarm limits
58 mm glass fibre filter
Easy systems integration via RS232 serial interface
Features
Measuring range for artificial beta activity concentration 100 - 105 Bq/m3 related to 60 min. sampling time
Fixed filter detector assembly comprising a sealed proportional counter tube with lead shielding
Aerosol filter: 58 mm, grade S, in leakage free filter holder
Air flow app. 5m3/h
Measuring electronics FHT 1100 with NetView compatible transmission protocol
