KGK, which developed the world's smallest probes "Chibi-ta-kun" and "Pechako-san," manufactures and sells insertion probes. These probes are used for thickness measurement and ultrasonic flaw detection by being inserted from the end faces of pipes such as heat exchanger tubes and hollow shafts. Additionally, insertion-type probes are useful for inspecting narrow and complex structures, such as the insertion parts of inspection jigs for aircraft engines. The insertion-type probes include various types, such as multi-channel probes that can be used in arrays, dual- element probes designed for thickness measurement, mirror-type reflective probes used for ultrasonic flaw detection and thickness measurement, angle-variable probes that can change the angle of the probe tip, and ultra-compact insertion probes. KGK designs and manufactures insertion-type probes tailored to the shape of the test specimen and the customer's requirements. Please contact us for more information.

In 1988, KGK developed the world's smallest ultrasonic probes: the ultra-compact probe “Chibita-kun” and the ultra-thin probe “Pechako-san.” Since then, KGK has offered a standard lineup of ultra-compact probes designed for ultrasonic testing in narrow and extremely small areas. Despite their small size, these reliable probes provide solid quality and performance. For vertical inspection and immersion testing, you can use the world’s smallest probes, “Chibita-kun” and “Pechako-san,” and for angled inspections, you can choose from ultra-compact angled probes such as the UX, UM, and UA series, depending on your application. ● Ideal for testing in narrow spaces, etc. ● Ultra-small probes can scan surfaces that cannot be scanned with standard probes. ● ChibiTa-kun has φ2×3mmL (minimum) ● PechaKo-san has a thickness of 1mm ● We also welcome inquiries regarding size dimensions.
