MiniTest 400 - ultrasonic thickness testing

Product catalog summary

Overview: The MiniTest 400 series comprises portable, hand-held ultrasonic thickness gauges designed for precision measurement across various materials such as stainless steel, aluminum, glass, and plastics. These devices are suitable for industrial environments, offering features like interchangeable transducers, automatic transducer identification, and zero adjustment.

Models and Features:

MiniTest 420: Basic model with essential functions for quick wall thickness measurement. It includes an integrated calibration block for zero-point calibration and a quick calibration button for easy handling.
MiniTest 430: Offers automatic zero-point calibration, integrated data memory, and USB interface for documentation. It features a high-speed scan for corrosion tests and compatibility with special transducers for high-temperature measurements.
MiniTest 440: Builds on the 430 model with the ability to measure through paint coatings using the U5.0E transducer.
MiniTest 450: High-end model with A-scan and B-scan visualization for enhanced measurement reliability, calibration control, and documentation.

Technical Specifications:

Measuring range: Echo-echo mode (3-25 mm), Pulse-echo mode (0.65-500 mm).
Display: 128x64 px backlit with resolution of 0.01 mm (0-99.9 mm) and 0.1 mm (>100 mm).
Sound velocity: 1,000 m/s to 9,999 m/s, with 9 preset velocities.
Data storage: 10 batches with up to 500 readings each, USB interface for data output.
Power supply: 2 AA batteries, providing approximately 64 hours of continuous use.

Transducers: The series includes a standard 5 MHz transducer, with optional transducers available for specialized applications. These transducers are compatible with all models except the MiniTest 420.

Applications: The MiniTest 400 series is ideal for quality assurance and corrosion testing, offering reliable measurements in harsh industrial conditions. The B-scan feature is particularly useful for detecting internal damage and material changes.

Standard Supply: Each model comes with a transducer, protective rubber case, coupling gel, batteries, USB cable, and zero standard accessory.
