Ultrasonic thickness gauge AD-3255 1 piece

[Applications] For thickness measurement of a wide range of materials including metals, glass, plastics, ceramics, and epoxies 【Features】 A single unit covers a wide measurement range: 0.8 to 300 mm Display resolution of 0.01mm (display can be switched between 0.01/0.1mm) Equipped with a scan mode that can measure the minimum thickness over a wide range Three types of probes can be used depending on the application, and the probes can be replaced (standard probe AD-3255-02 is included, others are sold separately) Capable of measuring thickness through paint (requires AD-3255-04 (sold separately)) The probe can be adjusted to the zero point. A test piece equivalent to 4 mm is included. Sound speed can be adjusted Coupling status is displayed, and contact status can be checked Backlight function (easy to see even in dark environments) Powered by 2 AA alkaline batteries (sold separately) Battery level display function Auto power off function Standard probe included Measurement method: Ultrasonic pulse reflection method Measurement frequency: Single point mode/7 times/second, Scan mode/16 times/second External dimensions: (W) 73 x (D) 32 x (H) 143 mm Measurement range (Pulse/Eco mode): 7MHz probe, AD-3255-02 (standard probe): 0.8 to 200.0 mm For 5MHz probe, AD-3255-03 (optional probe): 1.0 to 300.0 mm For 5MHz probe, AD-3255-04 (optional probe): 2.0 to 300.0 mm Measurement accuracy: ±0.1mm ±0.5% (measurement range: 0.8 to 50.0mm), ±0.1mm ±1.5% (measurement range: 50.1 to 300.0mm) *Measurement performance and accuracy are dependent on and affected by the condition of the surface of the object being measured. Accuracy guaranteed temperature range: 5 to 40°C Sound speed range: 1000 to 9999 m/s Display range: 0.65 to 600.0 mm Display resolution: 0.01mm/0.1mm selectable (display resolution of 200.1mm or more/0.1mm) Power supply: 2 AA batteries (sold separately) Size: 73 x 32 x 143mm Weight: Approx. 160g (excluding batteries) Accessories: 7MHz probe (AD-3255-02), 4mm equivalent test piece (AD-3255-01), carrying case, strap, empty contact medium bottle
