The Model 3A is identical to Ludlum's best selling, general purpose, Model 3 handheld analog ratemeter with the addition of an audible alarm.

The cast aluminum instrument housing with its separate battery compartment and accompanying metal handle offer an industrial robustness and quality that promote long-lasting protection and instrument life.
