Item Features: T9-130 Ultrasonic Thickness Gauge ,upgrade of 130d Description: The main purposeThis ultrasonic thickness gauge is an intelligent portable ultrasonic thickness gauge. It is controlled by a microprocessor and utilizes the principle of ultrasonic measurement to quickly and accurately measure the thickness and sonic velocity of a variety of materials. Accurate measurement: This ultrasonic thickness gauge with single-chip microprocessor technology, resolution is up to 0.01mm, stable measurement and fast response speed can be used to accurately measure various materials or parts in the field of industrial production, and it can also monitor various pipelines and pressure vessels in production equipment. It can measure the degree of thinning of various parts in time and accurately during use. Wide range of applications: metals, plastics, ceramics, glass and other good conductors of ultrasonic waves, as long as there are two parallel upper and lower sides, you can use this device to measure the thickness, such as aluminum, copper, gold, resin, water, glycerin, etc. Cast iron is not suitable for this device as its inner grains are too coarse. Measuring rangeMeasuring range: 0.8-500mm, 100 sets of data memory, measuring resolution: 0.01 mm (0.8-99.99 mm), 0.1 mm (100-500 mm) Translated with DeepL.com (free version) Specification: Measuring range: 0.8-500mm Operating frequency: 5MHz Lower limit of pipe measurement: 20x3mm Resolution: 0.01mm (1.00-99.99mm), 0.1mm (100-350mm) Accuracy: H<10mm: 0.05mm, 10-99mm: 0.01+H/200 mm, >100mm: 0.1+H/100 mm (H thickness of the material to be measured) Power supply Battery specification: 3x1.5V AA alkaline batteries Lasts approx. 20 hours Built-in 11 sets of commonly used material sound velocity values for users to select and use Customized and adjustable sound velocity function, adjustable sound velocity range: 1000~9999m/s 4mm self-calibration function LCD backlight can be selected to turn the function on or off Operating temperature 0~40Probe 0~60 Net weight of the host: 153g (incl. protective cover, but not battery) Ultrasonic thickness gauge host size: 72x135x36mm Translated with DeepL.com (free version) Note: The colors may be a little difference for the different monitor display.
