Breath-Alert Mk4 Breathing Monitor

The Breath-Alert™ Mk4 respiratory monitor is a simple yet sensitive and reliable device for monitoring breathing. A heat-sensitive sensor is placed in the breath pathway and detects each breath. If a breath does not take place within a selected time interval an alarm will sound. This monitor takes 4 x rechargeable AA NiMH batteries (do not use Alkaline AA batteries as this will damage the electric circuit).
