About This

• 【Important Notice for Buyers】 - This ultrasonic thickness gauge is not designed for measuring coating thickness on metal substrates or for use on cast iron, as its coarse crystalline grain structure prevents reliable readings, and you must always apply the included coupling agent to ensure accurate measurements.
• 1.【Precision Measurement Range for Industrial】 - This ultrasonic thickness gauge accurately measures material thickness from 1 mm to 400 mm (0.04 in to 15.75 in) on metals like steel, aluminum, and copper, as well as plastic, ceramics, glass, and other homogeneous materials using advanced ultrasonic wave technology, making it perfect for non-destructive inspection of pipelines, structural components, and precision machinery parts.
• 2.【High-Accuracy Dual-Crystal Probe】 - This metal thickness gauge delivers ±0.1 mm accuracy with a fine 0.01 mm resolution for critical inspections, and its industrial-grade dual-crystal probe effectively minimizes blind zones to give you consistently reliable readings, while the included 4 mm reference block pre-set to a sound velocity of 5740 m/s keeps calibration stable and trustworthy even in harsh working environments.
• 3.【Customizable Sound Velocity】 - With a wide adjustable sound velocity range from 1,000 to 9,999 m/s (0.039 to 0.393 in/μs), this thickness gauge lets you easily tailor measurements to virtually any material, while the clear display conveniently shows MIN/MAX statistics and lets you instantly switch between millimeter and inch units for fast, flexible on-site inspections.
• 4.【Rugged Design for Demanding Industries】 - Built to handle the demanding conditions of oil and gas, aerospace, shipbuilding, and automotive work, this ultrasonic thickness gauge gives field technicians and QA inspectors the portable, durable tool they can rely on, complete with a shock-resistant case, AAA batteries, and a backlit display that keeps every reading clear even in low-light environments.
• 5.【3 Years Wa-rran-ty】 - Every ultrasonic thickness gauge is thoroughly checked so you can buy with complete confidence, and we back your purchase with a full 3-year warranty that covers free maintenance, no-hassle refunds or exchanges, plus 24/7 access to our professional technicians for expert diagnostics and after-sales support.
