OBT320 Ultrasonic Thickness Gauge

OBT320 Ultrasonic Thickness Gauge
Ultrasonic Thickness Gauge OBT320 is a new generation of intelligent ultrasonic thickness gauge, using the latest high performance and low power consumption microprocessor technology, based on the principle of ultrasonic measurement, to measure the thickness of metal, glass, ceramics and other materials, and the materials of sound velocity measurement. Is widely used in all kinds of plate, pipe wall thickness, the boiler container wall thickness, all kinds of pipeline and pressure vessel, thickness measurement, monitor them in the process of using the degree of corrosion after thinning. With communication software, can be connected to computer.
Main function:
l Suitable for measuring metal (such as steel, cast iron, aluminum, copper, etc.), plastic, ceramic, glass, glass fiber and other any good conductors of ultrasonic thickness.
l Can be equipped with a variety of different frequency, chip size, double crystal probe use.
l  Have probe zero calibration, a two-point calibration function, can be automatically on system error correction.
l Thickness can be known the sound velocity measurement, in order to improve the accuracy of measurement.
l With functions of coupling status alerts.
l LED backlight display, convenient to use in dark environment.
l The battery indicator function, can real-time display the battery remaining power.
l  With automatic power saving function dormancy, automatic shutdown, etc.
l Small, portable, high reliability, suitable for bad operating environment, vibration, impact resistance and electromagnetic interference.
l The background data processing function; PC communication function; printing support.
