ULTRASONIC THICKNESS GAUGE -- Backlit digital thickness gauge, which can measure a wide range of materials, with a high-precision measuring probe.
SELF-CALIBRATION -- Equipped with a 4mm thick calibration block, used after calibration, it can measure the range of 1-225mm, with a high resolution of 0.01mm.
10 DATA STORAGES -- record important data for later query, can store material thickness data, and also store sound speed data.
SPEED OF SOUND CAN BE ADJUSTED -- 1000-9999m/s speed adjustment, which is suitable for measuring a variety of materials.
