Double – Gate Flaw Detector with Reporting – GAOTek

Description Overview GAOTek Double-Gate Flaw Detector with Reporting is a highly advanced device designed for precise flaw detection and material evaluation across a wide range of industrial applications. It provides a user-friendly interface with guided probe calibration and interactive dialog boxes, eliminating the need to constantly refer to manuals. This product is equipped with advanced tools such as color etching B-scan and spheroidization rate analysis, making it suitable for highly demanding testing environments. With repeat emissivity adjustable from 10 to 10,000 Hz and ultra-high signal-to-noise ratio, it delivers clear and stable waveforms with strong anti-interference performance. The device features high-speed 12-bit AD sampling, supporting probes up to 25 MHz, ensuring extremely high sensitivity and resolution for detecting minute defects. Built-in Bluetooth wireless transmission allows on-site report generation via mobile applications, while reports can also be printed or exported in PDF format. This product meets IP65 protection standards with a durable alloy and silicone shell, offering water and dust resistance along with a damping bracket for stability. Powered by a high-performance lithium battery, it supports up to 15 hours of continuous operation per charge, with the option for extended usage using dual batteries. With a measurement resolution as fine as 0.001 mm and capability to detect thin materials (as low as 0.15 mm for steel and 0.05 mm for plastic), this device overcomes coating interference effectively. Its wide range of detection functions, such as automatic calibration, echo envelope memory, gain compensation, and real-time B-scan imaging, ensures accurate and reliable flaw detection in diverse environments   Features  High-resolution 12-bit AD converter with 400 MHz sampling for precise detection Wide detection range: 0.15 mm to 49.21 ft (15 m) steel, up to 98.43 ft (30 m) transmission Adjustable repeat emissivity from 10 to 10,000 Hz for flexible applications Ultra-high signal-to-noise ratio ensuring clear and stable waveforms Multiple probe compatibility: straight, crystal, and penetration probes Dual gate alarm system with buzzer and LED indicators for real-time alerts Automatic calibration and gain compensation for efficient flaw detection Storage for up to 1000 A-scan waveforms with USB export and PDF reporting Bluetooth connectivity for mobile and PC data transfer and report management Long-lasting lithium battery with 15-hour continuous operation Durable IP65-rated alloy and silicone shell, resistant to water, dust, and impact   Technical Specifications Detection Range 0.15 mm to 49.21 ft (15 m) steel medium, longitudinal wave; 98.43 ft (30 m) transmission (expandable) Speed of Sound Range 100 m/s to 20,000 m/s Repeated Emissivity Adjustable from 10 Hz to 10,000 Hz Dynamic Range ≥38 dB Vertical Linearity Error ≤1.5% Horizontal Linear Error ≤0.2% Resolution >40 dB (5P14) Sensitivity Margin >66 dB (200 mm deep, 2 flat bottom hole) Digital Suppression 0% to 80%, without affecting linearity and gain Probe Types Straight probe, crystal probe, penetration probe Gate Inlet gate, loss gate; Single gate, double gate Alarm Buzzer alarm, LED light alarm Power Supply 9V DC Battery Working Time 15 hours Pulse Amplitude 100V, 200V, 300V, 400V, 500V selectable in grades, wide probe compatibility Pulse Width Adjustable from 0.03 to 0.51 µs to match different probe frequencies Probe Damping 50Ω, 100Ω, 150Ω, 400Ω Hardware Real-Time Sampling High-resolution 12-bit AD converter, 400 MHz sampling speed, high-fidelity waveform Detection Methods Positive half-wave, negative half-wave, full wave, radio frequency detection Filtering Frequency Band 0.1 MHz to 450 MHz Gate Reading Single gate and double gate reading; peak reading inside the gate Total Gain 120 dB (step values of 0.1 dB, 1 dB, 2 dB, and 6 dB) Plug and Socket BNC or LEMO optional Relative Humidity 20 to 95% RH Ambient Temperature 14 °F to 122 °F (-10 °C to 50 °C) Weight 2.65 lb (1.2 kg) External Dimensions 10.24 in x 6.89 in x 2.36 in (260 mm x 175 mm x 60 mm)
