Gas sensor SONOCHECK® ABD

medicalminiatureultrasonic

Product description
The SONOCHECK air bubble sensors, models ABD05 and ABD07, are designed for medical applications with elevated safety requirements. These sensors detect air and gas bubbles contactlessly in tubing carrying fluids such as blood, blood plasma, water or saline and also provide wet/dry indication. In medical systems the sensors primarily serve to protect patients from hazardous air infusion.
