MiniTest 745 Coating Thickness Gauge
Interchangeable Probes and SIDSP® Technology
The MiniTest 745 is the complete solution for quality control in coating thickness measurement. Designed for maximum flexibility, this gauge allows you to easily convert its integrated sensor into an external one, adapting to inspection needs in hard-to-reach areas. Its ability to connect probes via cable or wirelessly via Bluetooth makes it a versatile tool for industries such as automotive, shipbuilding, bridge engineering, and electroplating.
Key Features of the MiniTest 745:
- Interchangeable Probes: Allows the use of the integrated sensor or the connection of external probes, either by cable or via Bluetooth, to reach areas that are difficult to access.
- Ergonomic Design: Its rounded shape fits perfectly in the palm of your hand, providing comfortable and efficient handling.
- Adjustable Measurement Speed: Offers the option to adjust the measurement speed, enabling multiple readings quickly at medium precision or fewer readings with increased accuracy according to user requirements.
- SIDSP® Technology: Incorporates SIDSP® sensors (Sensor-Integrated Digital Signal Processing) that digitally process signals at the point of measurement with 32-bit precision, setting a new standard in coating thickness measurement. This technology improves signal stability, is insensitive to temperature changes, compensates for substrate conductivity, and is highly wear-resistant.
- Predefined Calibration: Integrated calibration methods adapt to a wide range of surface conditions and precision requirements, ensuring consistent and reliable results.
- Data Transfer Software: Includes MSoft 7 basic software, which facilitates real-time data transfer and analysis.
Key Benefits:
- Non-Destructive Measurements: Obtain accurate readings without damaging the coating surface, which is essential for maintaining product integrity.
- High Precision and Consistency: Advanced SIDSP® technology and predefined calibration ensure exact measurements, even under intensive use and on irregular surfaces.
- Flexibility and Productivity: The ability to adjust the measurement speed and the option for probe connection offer great versatility, allowing rapid multiple readings or fewer readings with enhanced accuracy, adapting to different applications and environments.
- Robust and Durable Design: Manufactured to operate in harsh environments, the MiniTest 745 guarantees a long service life and exceptional resistance to shocks and impacts, making it ideal for fieldwork and demanding industrial applications.
