NM01TG900+
The NDT Systems TG-900+ Ultrasonic Thickness Gauge is a cutting-edge, high-resolution, and highly durable handheld instrument designed for precise and reliable thickness measurements in a wide array of industrial and field applications. Its robust design and extended battery life make it an excellent choice for demanding conditions.
Key Features & Benefits:
High-Resolution Measurement: The TG-900+ offers exceptional measurement resolution (typically down to 0.0001 inches or 0.0025 mm), allowing for the detection of very small thickness variations and precise characterization of materials.
Handheld and Portable: Designed for convenience and ease of use in the field, its compact and lightweight form factor ensures comfortable operation over extended periods.
Unique Protection from Dust and Moisture (IP65 Rated): A key differentiator, the TG-900+ boasts an IP65 rating, meaning it is protected against dust ingress and low-pressure water jets from any direction. This makes it highly suitable for harsh industrial environments, ensuring reliability in dusty, humid, or outdoor conditions.
Unprecedented Autonomy (Up to 200 hours of continuous operation): Powered by standard AA batteries (3x AA, confirmed from manual), the gauge offers an impressive battery life of up to 200 hours on a single set. This significantly reduces downtime for battery changes and is a major advantage for prolonged field work.
Convenient and Easy to Use: The instrument features a user-friendly interface with a minimum number of controls, making it straightforward to operate for both experienced professionals and new users. It often includes a high-brightness color display and intuitive menus.
Versatile Measurement Modes: Typically includes various measurement modes to suit different applications, such as:
Digital Mode: Standard thickness readout.
B-Scan Mode: Allows the user to get a cross-sectional profile of the material, which is invaluable for visualizing corrosion or pitting.
Echo-to-Echo / Through-Coat Mode (Optional/Advanced Models): Capable of measuring material thickness through coatings (like paint or rust) without including the coating thickness in the reading.
Broad Application Range: Suitable for thickness measurements on a wide range of materials, including metals, plastics, composites, glass, and rubber. It's ideal for inspecting tubes, pipes, tanks, pressure vessels, and for corrosion/pitting measurements.
Custom Probe Setup & Material Velocities: Allows for custom probe configurations and features preset ultrasound material velocities for common materials, enhancing flexibility and accuracy.
Acoustic Contact Indicator: Provides visual feedback to ensure proper probe coupling for reliable measurements.
NDT Systems Quality: Manufactured by NDT Systems, Inc., a reputable company known for producing high-quality and reliable non-destructive testing equipment.
