Product Description

Bench Top Breathing Effort Tester       A simple, easy-to-use device for quickly testing the initial inhalation and exhalation effort of any regulator's second stage. Merely attach a special probe, perform a breathing cycle, and read a gauge! The probe will fit virtually all existing regulators; in many cases, removing the mouthpiece is not even necessary! Breathing efforts are read directly in inches of water resistance on a dual-scale, 4.5" Magnehelic gauge. When employed in tandem with a #48160 Bench top Intermediate Pressure Tester, highly accurate regulator function parameters can be ascertained. Hosed in a handsome, custom Plexiglas housing. A must for every fledgling scuba repair department. Special Note On Using #48155 & #48160 in unison: Initial Cracking Effort is perhaps the most critical physiologic parameter a dive technician must measure. This, of course, is the amount of respiratory work that a diver must exert each and every time he breathes to initiate air flow from the regulator. Some people measure this effort with a Magnehelic Gauge alone; others do it empirically by the sound or feel of the air flow. These methods are far less precise than using the Magnehelic Gauge (#48155) in conjunction with an Intermediate Pressure (IP) Tester (#48160). With the instruments side-by-side for easy viewing, put the probe from the Magnehelic into the regulator's mouthpiece. Inhale softly and slowly through the probe, watching the intermediate Pressure Gauge (#48160) which has been attached to regulator's BC hose. The instant the IP gauge needle twitches or dips down, quickly read the Magnehelic Gauge. This procedure yeilds the most accurate measurements possible!
