Leak Detector II AAM-PWLEAK02 Rental

Leak Detector II AAM-PWLEAK02 Rental

It is an ultrasonic detector with a parabolic microphone that can identify leak locations and detect bearing abnormalities!

The "Leak Detector II AAM-PWLEAK02" is an ultrasonic detector equipped with a parabolic microphone that sensitively captures ultrasonic waves generated by gas leaks from piping, damage to rotating machine bearings, or circulation issues. It can identify leak points and detect bearing abnormalities. Abnormalities such as damage to bearings or lubrication issues manifest not only as vibrations or temperature changes but also accompany ultrasonic emissions. Additionally, it is known that ultrasonic waves are generated by solid friction, such as belt slippage in belt-driven equipment. The "Leak Detector II AAM-PWLEAK02" detects such ultrasonic waves and notifies users through a bar graph and numerical display on the LED panel, as well as simulated sounds through headphones. It is effective for detecting air leaks from piping and gas leaks from various equipment, making it a valuable tool for energy conservation, environmental protection, and safety measures across a wide range of fields. For more details, please contact us or download the catalog.

Leak Detector LD239

Leak Detector LD239

Achieved a size and weight reduction of 1/3 or less compared to conventional models, along with approximately 20 times higher sensitivity and high stability.

With the latest MEMS technology, we have achieved miniaturization of the sensor and cell, which are the core components, and stabilization of the suction pump, balancing compactness with performance improvement. As a result, we have achieved a size and weight reduction to less than one-third of conventional models, along with approximately 20 times higher sensitivity and high stability, realizing a reliable leak detector. It has become even easier to carry with its portable size.

Leak Detector "LD400"

Leak Detector "LD400"

A sturdy and lightweight leak detector that is convenient to carry. It detects invisible leak points using ultrasound.

When compressed air or gas leaks from piping lines (for example, due to reasons such as loose flange screws or corrosion), ultrasonic waves are generated. By using the leak detector LD400, it is possible to detect leak points that are inaudible to the human ear and too small to be seen from several meters away. The design of the horn-shaped sound collector does not interfere with positioning using a laser pointer. A handheld ultrasonic transducer is used to detect leak points in the pressure reduction system. The transducer is installed close to the piping line. Ultrasonic signals are generated from leak points that the LD400 can detect. Extremely small leaks from hatches, doors, windows, etc., can also be detected. 【Features】 ○ Durable and lightweight, easy to carry ○ Specially designed horn-shaped sound collector makes it easy to locate leak points ○ Built-in rechargeable lithium-ion battery ○ Continuous use for 10 hours (fully charged) ○ Easy operation with a keypad For more details, please contact us or download the catalog.

Leak Detector ASM Series

Leak Detector ASM Series

Industry-leading basic performance and track record.

This is a device used to check for leaks, which is the biggest concern when creating a vacuum. It is also called a leak tester. Generally, helium is considered the best tracer for the following reasons: • Light → Easily diffuses • Small molecules → Can penetrate extremely small holes • Chemically stable → Does not contaminate products and is harmless to humans • Almost non-existent in the atmosphere → Prevents false detections by the measuring device • Worldwide service ⇒ Service support is available not only in Japan but globally • Extensive lineup ⇒ Allows selection of the most suitable model for specific applications
