Introduction
This operations manual describes “Leak Detector II” portable ultrasonic detection tool
operations.
Caution Leak Detector II cannot be prescribed for specific accuracy of the measurement
target. Use this product for rough estimates in the presence of ultrasound or to
check the intensity of air leaks.
Caution Avoid using this product for toxic gas or explosive gas leak tests.

Section 1. Overview
Leak Detector II is an ultrasonic detection tool with the following configuration.
•Sound collecting parabolic hood with high directivity sound collection characteristics .
•The ultrasound sensor can be detached from the sound collecting parabolic hood,
enabling mounting of a sound collecting probe.
•The Indicator/Operations panel is used for expressing detected signal intensity on a
bar graph and using numerical values, setting the signal amplification level &
headphone volumeNOTE and to save data.
NOTE: 40 kHz ultrasound is detected by a sensor. This ultrasound is converted to
the audible sound and output from the headphone.
Caution This device is used for rough estimates of ultrasound intensity and air leak volume.
Always use measurement results indicated numerically as rough estimates.

1.1 Functions Overview
•Detects ultrasound in the 40 kHz range
•Can identify the direction of the ultrasound source using the directivity of the sound
collecting parabolic hood.
•The ultrasound source can be pinpointed by attaching the sound collector probe.
•Higher sensitivity ultrasonic detection is enabled with the sound collecting parabolic
hood effect.
•The ultrasound intensity is indicated in double digit numerical values and expressed
on a 10-step LED bar graph.
•The numerical value indicator enables selection of a dB value and leak volume level
indicator.
•The sensor sensitivity and headphone volume enables 8-step adjustments to be
performed.
•500 measurement data points can be saved in the main unit and transferred to a PC.
Caution The dB values of the Leak Detector II may not be consistent with the sound
pressure values measured with an general ultrasonic detector.This is due to the
effects of parabola directivity, sound collecting characteristics, built-in ultrasound
sensor frequency characteristics and directivity of the Leak Detector II.
Caution The ultrasound intensity is converted into an air leak volume that is displayed (0.1
to 1.9 Nm3/h range). Ultrasound level and leak volume level conversion are based
on specific characteristics, which may not agree with the actual leak volume. The
leak volume indicator of the Leak Detector II is to be used for rough estimates only
.
