TK-C7 High Precision Digital Ultrasonic Thickness Gauge

Professional ultrasonic thickness measuring instrument with 0.15-2000mm measurement range, multiple measurement modes, and Bluetooth data transmission capabilities.

Product Overview

High precision digital ultrasonic thickness measuring instrument featuring multiple measurement modes and Bluetooth communication. This instrument employs pulse-echo ultrasonic measurement technology designed for materials where ultrasonic waves travel at constant internal velocity and produce clear backwall reflection.

The TK-U7 model with 5mm contact diameter probe can verify genuine gold coins and includes manual velocity setting capability. With ultra-high measurement resolution of 0.001mm, it delivers precise thickness measurement for various plates and machined parts including metals (steel, cast iron, aluminum, copper), plastics, ceramics, glass, fiberglass, and other materials with good ultrasonic conductivity.

Widely used in petroleum, chemical, metallurgy, shipbuilding, aviation, aerospace, and other industrial sectors.

Key Features

Multiple measurement modes: Pulse-Echo (P-E), Interface-Echo (I-E), and Echo-Echo (E-E) for accurate substrate thickness measurement
E-E mode enables substrate thickness measurement through coating layers (Coating Version measures substrate and coating thickness simultaneously)
Real-time temperature compensation eliminates measurement errors from probe temperature variation
Factory pre-calibrated probe ready for direct operation without frequent recalibration
16 adjustable gain levels and 7 adjustable transmit levels for optimal performance
Compatible with wide range of single-element and dual-element dedicated probes
Probe calibration and two-point calibration functions for automatic error correction
Inverse sound velocity calculation based on known workpiece thickness
Multiple measuring modes: single-point, scan, upper/lower limit scan, boundary scan, and difference measurement
Built-in keypad lock prevents accidental parameter modification
Presettable thickness thresholds with automatic buzzer alarm
Comprehensive display including thickness, sound velocity, coupling status, battery level, and timestamp
Complete measurement record storage with thickness, sound velocity, and testing time data
Portable thermal printer compatibility for record printing
Bluetooth/Mini-USB real-time data communication with PCs and smart devices
Intelligent voice broadcast of measured results (Voice Version)
Sound velocity measurement and spheroidization grade classification for ductile iron (Sound Velocity Version)
Lower-limit measurement for workpieces with internal defects or multi-layer materials (Lower Limit Version)
Customizable hardware and software services including power supply refitting and communication protocol customization
