TT-200 Ultrasonic Thickness Gauge Applications The TT-200 Ultrasonic Thickness Gauge is a high-precision, multi-mode thickness measurement instrument designed for testing a wide range of materials including metals, plastics, ceramics, composites, epoxies, and glass. It is suitable for manufacturing, metal processing, quality control, maintenance, aerospace, automotive, petrochemical, and engineering industries. In addition to standard thickness measurement, the TT-200 features Echo-Echo technology for measuring material thickness through coatings without removing paint or protective layers. The instrument also includes a special test mode for identifying precious metals and checking the purity of gold bars, silver bars, gold coins, silver coins, and similar valuable materials. Features • Multi-mode ultrasonic thickness measurement • Pulse-Echo (P-E) mode for standard thickness measurement • Echo-Echo (I-E) mode for thickness measurement through coatings • Dedicated TEST mode for precious metal identification • Suitable for metals, plastics, ceramics, composites, epoxies, and glass • Measures thickness without removing paint or coating layers • Through-coating measurement up to 1.5 mm coating thickness • High-precision timing chip with advanced V-path calibration technology • Wide measuring range and excellent measurement accuracy • Adjustable sound velocity for different materials • Stores measurement values, sound velocity, and time information • Adjustable display resolution: 0.1 mm or 0.01 mm • LCD display with adjustable contrast and LED backlight • Portable, lightweight, and easy-to-use design • Long battery life for field inspections Technical Specifications Model: TT-200 Measurement Modes: Pulse-Echo (P-E), Echo-Echo (I-E), TEST Mode Measuring Range (Pulse-Echo Mode): 0.65 mm to 500 mm (Steel) Measuring Range (Echo-Echo Mode): 1 mm to 75 mm (Steel) Maximum Coating Thickness: 1.5 mm Display Resolution: 0.1 mm / 0.01 mm Measurement Accuracy: ±0.4% H (H = Thickness of the Workpiece) Measurement Rate: 4 Measurements per Second Sound Velocity Range: 1000 to 9999 m/s Display: FSTN LCD with LED Backlight Power Supply: 2 × 1.5V AA Batteries Continuous Operating Time: Up to 50 Hours (Without Backlight) Data Storage: 500 Measurement Records Including Time and Sound Velocity Data Auto Power Off: Automatic Shutdown After 2 Minutes of Inactivity (Adjustable) Display Information: Thickness Value, Coupling Status, Battery Status, Calibration Status, Sound Velocity, Time, and More Dimensions: 155 × 68 × 27 mm Weight: 230 g Optional Probe Selection 5 MHz Standard Probe Universal Applications Contact Diameter: 10 mm Measuring Range: 0.65 – 500 mm Temperature Range: -10°C to 60°C 2 MHz Coarse Crystal Probe Special Applications Contact Diameter: 12 mm Measuring Range: 2.0 – 500 mm Temperature Range: -10°C to 60°C 7.5 MHz Micro Diameter Probe Small Area Measurements Contact Diameter: 6 mm Measuring Range: 0.85 – 40 mm Temperature Range: -10°C to 60°C High Temperature Probe (H2M) High Temperature Applications Frequency: 3 MHz Contact Diameter: 12 mm Measuring Range: 4.0 – 80 mm Temperature Range: -10°C to 310°C Product Video: Paste YouTube Video Link Here For more information about the TT-200 Ultrasonic Thickness Gauge, please contact us at 08045134493 or email vhk_08@yahoo.com.
