Description
Model ALCAM provides inlet connection for connecting the air suction vacuum line. However, air sampling pump unit also can be supplied as an optional accessory. It is expected that the flow range should be between 40 to 70 LPM. Rotary vanes based dry pump with open air suction capacity up to 125 LPM is supplied for 24 hours nonstop operation as an optional accessory.
Connectivity of ALCAM to network or PC is provided through RS-485 / Ethernet. Modbus based Data Transfer software is supplied as an option. MODBUS protocol based registers’ output is made available for data transfer.
Wall mountable Continuous Air Monitoring System model ALCAM is supplied in rack. This rack (depth 23 cms) contains the 2” dia ZnS(Ag) Alpha detector on 2” dia PMT, Filter holder assembly, air flow measuring unit and electronic unit for display of Alpha activity.
