1. THEORY OF ULTRASONIC GAS LEAKAGE DETECTION Human ear can hear sound frequency up to 18 KHz. The sound frequency above 20 KHz is categorized as ultrasonic sound which is not audible. Ultrasonic sound is very directional in nature. We can utilize this nature to pinpoint the exact origin of the sound source where the leak is located.
2. FEATURES This ULTRASONIC GAS LEAKAGE DETECTOR is designed to locate the source of the ultrasonic emissions generated by gas or air leaks. The leakage level is displayed by "Bar LED Display Panel", and is covered to audible sound by either internal buzzer or to external optional earphone).

5. MISCELLANEOUS ACCESSORIES (accessories included) (1) Rubber bottle plug with plastic tubing. This accessory can be used to extend the sensor horn, carrying the sound from places too tight, too dangerous for human contact, to eliminate the background noise. Refer to fIG. 2. Fig.
6. MEASURING PROCEDURE (1) Plug in the optional earphone into the "Earphone Jack"(4-7, Fig. 1) if so desired. (2) Press the "Battery Test Button"(4-5, Fig. 1) to check the battery level. The LED display panel will lit in "BAT. OK" position if it is adequately powered, otherwise, the battery should be replaced.
7. IMPORTANCE of THE MEASURING WARNING (1) If there is quite a bit of background noise, you may muffle the leak detector to hear the actual leaks. This can be accomplished with the "rubber plug with plastic tubing" & "PVC pipe" MISCELLANEOUS ACCESSORIES).
(7) Electrical arcing. Electrical arcing can be detected with the ultrasonic leakage detector. Arcing produces a rich ultrasonic spectrum that is quite noisy. Used the PVC pipe accessory to extend the sensor horn of the dector for safety purpose. (8) To check the bearing problems. (9) Bake system.
