Specifications are subject to change without notice
Specifications are for
models with one GM tube.
Models with 4 GM tubes (RadAl™-1/4 and
RadAl™-1-WP/4
have twice the sensitivity
and speed.
Connections to relay and communication ports are by terminals
accessible through wall passages.
Computer programs can be provided to demonstrate and test communications.
A detailed report: "sensitivity
tests using Am241 and Cs137 sources"
is available documenting alarm response thresholds.
No toxic nor radioactive materials are used in these
instrument!
