Description
The ATG400 ultrasonic through coating thickness gauge can be used in three modes; pulse -echo mode for normal thickness gauging without coatings; echo – echo mode for measuring through thin paint layers and multiple echo for measuring through thicker coatings, measuring only the metal thickness.
ATG400 Through Coating Thickness Gauge Specification:
- Operating principle: Ultrasonic pulse/echo method with dual-element probes
- Measuring Range: 0.8~300mm (standard mode) / 3~18mm (coating mode) (Dependent on the probe, materials and surface conditions)
- Unit and Resolution: mm: 0.01 or 0.1 / inch: 0.001 or 0.01
- Material’s Velocity Range: 1000~9999 m/s ; 0.0394~0.3937in/us ±0.05mm (≤10mm)
- Linearity Error: ±0.5% H + 0.01 (≥10mm) (H-the height of the analyte)
- Display Screen: 128 x 64 dot-matrix LCD (42 x 57mm) With backlight
- Probe zero adjustment (Selectable): 1-point calibration: normal measurement – 2-point calibration: curve surface measurement or other special application with a high precision
- Data Storage: It can store 500 thickness values divided into 5 arrays
- Minimum value checking: Move the probe along the surface of the testing material and the ATG400 gauge is able to automatically find the thinnest point.
- Warning function: If the measured value exceeds the pre-set thickness limit, the warning tone will sound.
- V-Path Modification: Auto V beam path modification to compensate for the nonlinearity of twin crytsal probes.
- Repeatability: ±0.05mm
- Auto shut-off: Will shut off automatically after 5 min. of non-use
- Working Temperature: -10℃ to +50℃
- Size: 149 × 73mm × 32mm (H × W × D)
- Weight: 200g (including batteries)
- Power: 2 x 1.5V AA alkaline batteries – Warning with low battery voltage
- Measurement update rate: 4 Hz in standard measurement mode – 25 Hz in MIN capture mode
- Operating time: Up to 200 hours (without backlight) with alkaline batteries, depending on operating mode
