Abstract:
An energy efficient, easy to read, portable digital gas leak detector for testing air leakage in oxygen supply equipment comprising:means for introducing pressurized gas into said equipment in fluid communication with said equipment; means for manually manipulating the pressure of the gas introduced into said equipment in fluid communication with said means for introducing pressurized gas; means for measuring said pressure and leakage of said introduced gas in said equipment in fluid communication with said means for introducing pressurized gas; and means for displaying said pressure and said leakage in electronic communication with said means for measuring said pressure and said leakage; said means for displaying said pressure and said leakage includes an LCD pressure display and an LCD flow display each in electronic communication with a central processing unit (CPU); a power supply in electronic communication with the CPU; and a pressure switch in electronic communication with the CPU, whereby the power supply is only engaged to the CPU at or above a predetermined gas pressure.
