Detail Multi-Echo Ultrasonic Thickness Gauge
Testing Instrument
Multi-Echo Ultrasonic Thickness Gauge
The LM series ultrasonic thickness gauge can measure the thickness of metal materials, high-temperature pipelines, pipes, plates (steel plates, aluminum plates), plastics, iron pipes, PVC pipes, glass and other materials. Can be applied to the detection fields of manufacturing industry, metal processing industry, chemical industry, commodity inspection industry and the like, can also monitor various pipelines and pressure vessels in production equipment and monitor the thinning degree of the pipelines and pressure vessels after being corroded in the use process, and is a corresponding instrument for material protection.
DESCRIPTION
Our company has introduced a hand-held precision ultrasonic thickness gauge LUM-3 using single crystal delay line probe, which uses single crystal delay probe and uses multiple echoes to improve accuracy, so that the resolution can reach 0.001mm and the lower limit of measurement can reach 0.30 mm. LM-3 has two working modes: normal and precise. The common mode adopts the interface wave-echo method, and the measuring range is 1.5 mm ~ 20 mm; The precision mode adopts echo-echo method, and the measurement range is 0.30mm ~ 10 mm.
Suitable for measuring flat sheet steel parts.
FEATURES
1. High precision, 0.001mm resolution
2. Suitable for measuring thin materials, can accurately and reliably measure 0.25mm flat thin steel plate material
3. Can penetrate through the coating, such as paint layer on the material, without polishing, can directly measure the thickness of the substrate
