Leeb330, Leeb331 and Leeb332 are durable metal-shell ultrasonic thickness gauges developed by Chongqing Leeb Instrument. Adopting advanced ultrasonic non-destructive testing technology, these portable meters can accurately measure the thickness of various uniform materials without damaging workpieces.
They are widely used to detect wall thickness, residual thickness, corrosion and wear degree of pipes, pressure vessels, steel plates and mechanical components. Equipped with automatic zero calibration, adjustable sound velocity and real-time coupling indication, the testers effectively reduce manual errors and ensure reliable measuring accuracy. The upper and lower limit alarm function helps operators quickly screen unqualified products and improve inspection efficiency.
All models adopt sturdy metal casing for enhanced durability and anti-drop performance. Adjustable LED backlight ensures clear reading in all light conditions. Dual unit switching and intelligent power-saving design adapt to long-time field operation. Leeb330 is cost-effective for routine testing, Leeb331 adds mass data storage function for record tracking, and Leeb332 provides ultra-high 0.01mm resolution for precision detection. They are reliable NDT testing equipment for petrochemical, shipbuilding, steel structure and mechanical manufacturing industries.
Leeb330 is the basic economical metal-shell model, with measuring range 0.7-300mm, 0.1mm resolution, standard testing accuracy ±(1%H+0.1)mm, supports sound velocity adjustment and tolerance alarm, no data storage function, suitable for daily routine thickness inspection.
Leeb331 is the standard upgraded model, inherits all functions of Leeb330, adds 2000 groups of data storage and data query function, with stable testing performance and complete basic functions, ideal for regular industrial quality detection and data recording scenarios.
Leeb332 is the high-end precision model, equipped with 0.01mm ultra-fine high resolution, retains 0.7-300mm wide measuring range and 2000 groups data storage, supports more accurate thickness measurement, perfectly meets high-precision testing and strict quality control requirements.
All three models feature unified dimension 150×55.5×23mm, total weight 420g, powered by 2 AAA batteries, working temperature range from -10℃ to 60℃, with excellent environmental adaptability.
