Algoleak Q&A

Even small leaks can be detected, but minimum detection depends on pressure, distance, and ambient noise. Catalog spec is 0.008 L/min @ 6 bar from 0.5 m.

The catalog specification is 150 m, but in typical operating factory conditions, detection up to ceiling height is often possible. Closer distances are more reliable, and longer distances work better for larger leaks. Line of sight (obstructions), reflections, and wind also affect detection, so for long distances the stable approach is "survey from an overview, then approach for precise identification."

Yes, in many cases. Even with high audible-range noise, it can isolate and identify ultrasonic components. However, detection may be more difficult when ultrasonic noise sources (air blow, friction, etc.) are nearby.

In most cases measurements can be taken while equipment is in operation. Shutdown is only required when safety prevents close approach, or when the leak sound is masked by other sound sources.

Yes. The camera visualizes directionality, making it easier to get a "general idea" even for high or hidden locations. For final identification and repair decisions, combine with ladders, aerial work platforms, or telephoto operation.

Generally yes, for gas leaks (with pressure differential), steam leaks, vacuum leaks, abnormal sound source searching, and electrical discharge inspection.

Yes, and CO2 emissions can also be displayed. Estimation requires setting pressure, operating hours, electricity unit price, etc.

A microSD card is included and data is saved as JPEG.

Yes, via LEAK ANALYZER software.

When measuring air leaks, you can avoid being misled by reflections as follows:

(1) When a point appears, swing the camera left and right.

- For sound reflections, the point jumps or drifts with camera movement.

- For actual leaks, the point stays in place and follows the camera movement.

(2) Measure from a different direction.

- If unsure whether it is a real leak, measure from another angle. False responses from sound reflections will disappear.

(3) Use focus mode.

- AL64 has a focus mode. A square frame appears in the center of the screen; only sounds within the frame are picked up, external sounds are excluded.

- Recommended usage: survey with focus mode off to find candidates, then turn focus mode on to pinpoint.

It detects the ultrasonic waves emitted when gas leaks. The frequency of gas leaks is characteristic at around 30-40 kHz. By setting the visualization frequency to this range, human voices and machine noise can be largely excluded, allowing gas leaks to be detected.

Yes. It can be adjusted in 0.1 kHz increments within the 2 kHz - 96 kHz range.

Detection is possible even under noise.

Since it detects a specified band within 2-96 kHz, it works in noisy environments with machinery. Gas leak frequency is characteristically around 30-40 kHz, so by setting visualization to this range, machine noise is largely excluded.

Two methods:

(1) Connect via USB Type-C to a PC USB port for wired extraction.

(2) Insert the microSD card into a PC.

Yes, partial discharge can be visualized. Four types of discharge — corona, floating, surface, and particle — in high-voltage systems can be visualized and identified.

Factories using gas, regardless of industry, adopt the device.

From an energy-saving perspective: automotive, food, beverage, metalworking, chemical, steel, and power industries.

For partial discharge prevention: aluminum producers, substations, electrical safety associations, and maintenance companies performing inspection work.

Recommended when you want to view densely clustered fittings or similar areas in more detail.

Sensitivity ranges from 5 (most sensitive) to 1 (least sensitive).

At sensitivity 5, smaller leaks are visualized, but various ambient sounds appear in noisy environments.

At sensitivity 1, ambient noise is less likely to be picked up, but small leaks may be missed.

We recommend level 3 when using in a factory during operation.

By default, the strongest sound source is displayed.

Switching to multi-source mode allows simultaneous display of multiple points if they have similar leak rates.

However, when one leak is large and another is small, only the larger one tends to be detected.

Note: multi-source mode picks up all frequencies close to gas leaks, so screen response may flicker.

For densely clustered areas like air fittings, we recommend focus mode.

Yes, you can also change to m³ or other units. If your facility has standardized units, you can switch accordingly.

2 years for the main device, 3 years for batteries.

Made in Japan.

Parts are supplied by Chinese manufacturers, but manufacturing itself is carried out in Japan.

Maintenance is performed in Japan.

No precision needles or measurement instruments are built in, so no calibration is required.

Demo unit loans are not provided in principle.

We accompany sales demos as standard, so please contact us.

There is no charge for demo accompaniment.

Approximately 1 hour total is expected for "device explanation and on-site demo accompaniment."
