NM01GELW1

Sonatest — SONAGEL-W1 Water-Based Couplant

Overview

The Sonatest SONAGEL-W1 is a water-based ultrasonic couplant designed to improve acoustic transmission between an ultrasonic transducer and the inspection surface. By reducing air at the contact interface, it helps ultrasonic energy enter the test material efficiently during thickness measurement and flaw-detection procedures.

Its ready-to-use formulation supports fast inspection setup without requiring dilution or mixing. The couplant is suitable for routine ultrasonic testing on metallic components, including surfaces that may be rough, pitted, curved, or uneven.

Supplied in a 1 L container, SKU SONAGEL-W1 provides a practical quantity for field technicians, fabrication facilities, maintenance departments, inspection laboratories, and QA/QC teams performing regular ultrasonic examinations.
