Description
Product Overview
The allsun Ultrasonic Leak Detector is engineered for professionals who demand precise, fast, and reliable leak detection across a wide range of industrial, commercial, and automotive applications. Built around a high‑sensitivity ultrasonic sensor that operates between 36 kHz and 44 kHz, the device captures the subtle acoustic signatures generated by escaping air, electrical corona, and mechanical wear such as bearing failures or valve leaks. The handheld unit houses two interchangeable probes – an air probe optimized for detecting pressurized leaks and a contact probe designed to sense vibrations directly from equipment surfaces. Both probes feature ergonomic grips and rugged ABS housings that withstand drops, dust, and moisture, making the detector suitable for field work in harsh environments.
Power is supplied by two 9 V zinc‑carbon batteries, delivering up to 12 hours of continuous operation. The detector includes dual alert modes: an audible tone that rises in pitch as the sensor approaches a leak source, and a visual LED bar graph that provides an immediate visual cue of leak intensity. A rotary volume knob lets users fine‑tune headphone output, ensuring that the device can be used comfortably for extended periods without causing ear fatigue. The unit’s compact dimensions (11.1 × 5.16 × 9.5 in) and lightweight design (2.16 lb) enable easy transport and one‑handed operation, while the built‑in tone generator allows users to test enclosure seals by emitting a known ultrasonic signal.
Usage
Designed for versatility, the allsun Ultrasonic Leak Detector excels in a variety of real‑world scenarios. In HVAC maintenance, technicians can quickly locate duct leaks, refrigerant pipe faults, and fan motor issues without dismantling the system. The air probe’s directional sensitivity makes it possible to pinpoint the exact location of a leak by following the rising tone and LED intensity, even when the source is hidden behind insulation or within tight spaces.
Automotive professionals benefit from the contact probe’s ability to detect internal engine problems such as failing valve seals, worn piston rings, or cracked exhaust manifolds. By placing the probe directly on engine components, the detector translates mechanical vibrations into audible cues, allowing mechanics to diagnose issues before they lead to costly repairs. The tone generator feature is especially useful for checking the integrity of vehicle doors, windows, and roof seals; simply place the generator inside the enclosure and listen for any ultrasonic escape that indicates a compromised seal.
In manufacturing and process industries, the detector assists in monitoring pressurized pipelines, steam traps, and pneumatic systems. Its battery‑powered, cordless operation means it can be used in remote locations where mains power is unavailable. The device’s visual LED display is valuable in noisy environments where auditory cues might be masked, ensuring that operators can still identify leak sources accurately. The detector’s operating humidity rating of up to 95 % and temperature tolerance up to 40 °C further guarantee reliable performance in demanding conditions.

FAQ
What types of leaks can the detector identify?
The detector can locate air leaks from ducts, pipes, and pressurized systems, as well as electrical corona discharges and mechanical faults such as bearing wear, valve leaks, and steam trap failures.
Do I need any special accessories to use the device?
No additional accessories are required for basic operation. The kit includes the handheld unit, both ultrasonic probes, a tone generator, and a pair of headphones. Batteries are not included, so you will need two 9 V zinc‑carbon batteries.
Can the detector be used in high‑humidity environments?
Yes, the detector is rated for up to 95 % relative humidity, making it suitable for use in moist industrial settings, HVAC inspections, and outdoor applications.
How does the tone generator help with enclosure seal testing?
The built‑in tone generator emits a known ultrasonic signal that can be placed inside an enclosure (such as a car door or window). By listening for the signal with the detector, you can quickly determine if the seal is intact or if ultrasonic energy is escaping, indicating a leak.
What warranty and support are provided?
Allsun offers a one‑year limited warranty covering manufacturing defects, along with responsive technical support via email and phone. Replacement parts and service are available through authorized distributors.
