Abstract
A hydrogen sensor ( ) protected from water vapor by a membrane ( ) indicates increases in hydrogen concentrations which are indicative of a leak in an absorption chiller ( ). A helium detector ( ), protected from water vapor and liquid water by a membrane ( ) and a vapor trap ( ), senses the presence of helium from a spray ( ) to locate the position of leaks. A hydrogen removing cell ( ) is tested by monitoring the variation with time of the hydrogen concentration before and after the cell is rendered inoperative.
