Designed to locate leaks in pressure and vacuum system.
It can be used to detect and locate the source of the ultrasonic emission generated by gas or liquid f1owing through a small restrictive opening.
lt uses the advanced ultrasonic sensing technique and features small size, light weight;reliable detection, easy use and utility.
1. Sense pressurized leaks, detects electrical arcing, and finds falling solenoids, valves and bearings .
2. Comes with a transmitter that emits an ultrasonic frequency to help locate leaaks that are not pressurized.Enough to emit frequencies the detector can pick up.(Only DY26)
3. Detects any pressurized leaking gas, including chlorofluoro carbon(CFCs), hydrofluoro carbon(HFCs),nitrogen(Ni), carbon dioxide(CO2) and steam.

Note :
1.There are many factors involved in the ultrasonic leak detection, such as the pressure within the vessel under test,hole shape, hole size, temperature etc. In some cases, the ultrasonic sound caused by leak is very weak,so you should set the DY26A's sensitivity to the highest level at the beginning of leak detection.
2.If the detected ultrasonic sound is too intense so that it is impossible to pinpoint the leak because the" ticking tone"is too high in frequency, you should decrease the sensitivity with the sensitivity knob.
3.In noisy environments, you can decrease the sensitivity appropriately to exclude the disturbance caused bynoise.
4.When DY26A detects ultrasonic sound, move its probe around the suspected leak to determinewhether the detected ultrasonic sound is from the suspected leak or from other areas.
5.Because ultrasonic sound attenuates rapidly when it travels over distance, move the probe of DY26Aas close as possible to the suspected leak, remember to decrease the sensitivity if necessary.During location, move the probe slowly.
Attention:
1. Ultrasonic leak detection involves multiple factors, such as the pressure inside the tested container,
Hole shape, hole size, temperature, etc. In some cases, the ultrasonic waves caused by leakage are weak,
So you should set the sensitivity of DY26A to the highest level at the beginning of the leak detection.
2. If the detected ultrasonic sound is too strong, the leak point cannot be determined because of the "ticking sound"
If the frequency is too high, the sensitivity knob should be used to reduce the sensitivity.
3. In noisy environments, you can reduce sensitivity appropriately to eliminate interference caused by noise.
When DY26A detects ultrasound, move its probe to the suspected leak location to determine
Is the detected ultrasound coming from a suspected leak or from another area.
5. Due to the rapid attenuation of ultrasound at long distances, please move the probe of DY26A
As close as possible to a suspected leak, please remember to reduce sensitivity if necessary.
During the positioning process, slowly move the probe.
