Spec：Used for measuring Leakage of system.
This Ultrasonic Gas Leakage Detector is designed tolocate the source of the ultrasonic emissions generated by gas or air leaks.The leakage level is displayed by "LED Display Panel", and is coveredto audible sound by either internalbuzzer or to external optional earphone.
Used for measuring Leakage of system. Applicable todetect Leaks in refrigeration and air condition systems, Leaks in heatingsystem, Internal leaks in steam transfers, Compressed air leaks, Tire &tube leaks, Engine seals, Electrical arcing, The bearing problems, Bake system.With the Ultrasonic transmitter, it is applicable to Air leaks around door& window gaskets & seals, Water leaks in roofs, Conduit & pipeidentification, Door & trunk seals, Windshield leaks.
Human ear can hear sound frequency up to 18 KHz. Thesound frequency above 20 KHz is categorized as ultrasonic sound which is notaudible. Ultrasonic sound is very directional in nature. We can utilize thisnature to pinpoint the exact origin of the sound source where the leak islocated. Physics tells us that the gas always flows from the higher pressureregion to the lower one. When the pressure difference is only a small opening,the turbulence created by the gas through the small hole then generatesultrasonic sound. In the non pressurized state, the ultrasonic transmitter isapplicable, ultrasonic wave can leak from the small hole. Ultrasonic gasleakage detector is designed based on the above simple physics.
Leakage Sensitivity Indicator：LED display panel & audible tone. (LED display is a relative measurement only. Audible tone is the frequency of the received ultrasonic sound divided by 32.)
Frequency Response：20 KHz to 100 Khz.
Power Supply：4x1.5 AAA(UM-4) battery
Power Consumption：Approx. DC 25 mA.
Operating Temperature：0 to 50 °C ( 32 to 122 °F ).
Operating Humidity：Max. 80% RH.
Weight：Approx. 140 g/0.31 lb (including battery).
