1 Overview

The model AT300 is a digital ultrasonic thickness gauge. Based on the same operating

principles as SONAR, the instrument is capable of measuring the thickness of various

materials with accuracy as high as 0.1/0.01 millimeters. It is suitable for a variety of metallic

and non-metallic materials.

1) Display：4.5 digits LCD with EL backlight.

2) Measuring Range：0.75～300mm (in Steel).

3) Sound Velocity Range: 1000~9999 m/s.

4) Resolution： AT300: 0.1/0.01mm

5) Accuracy： ±（0.5%Thickness+0.04）mm, depends on materials and conditions

6) Units: Metric/Imperial unit selectable.

7) Four measurements readings per second for single point measurement, and ten per

second for Scan Mode.

8) Memory for up to 20 files (up to 99 values for each file) of stored values.

9) Power Source：Two "AA" size, 1.5 Volt alkaline batteries. 100 hours typical operating

time (EL backlight off).

10) Communication：RS232 serial port for MAT300.

11) Outline dimensions：150×74×32 mm.

12) Weight：245g

1) Capable of performing measurements on a wide range of material, including metals,

plastic, ceramics, composites, epoxies, glass and other ultrasonic wave well-conductive

materials.

2) Transducer models are available for special application, including for coarse grain

material and high temperature applications.

3) Probe-Zero function, Sound-Velocity-Calibration function

4) Two-Point Calibration function.

5) Two work modes: Single point mode and Scan mode.

6) Coupling status indicator showing the coupling status.

7) Battery information indicates the rest capacity of the battery.

8) Auto sleep and auto power off function to conserve battery life.

9) Optional software to process the memory data on the PC for AT300

10) Optional thermal mini-printer to print the measured data via RS232 port for AT300

The digital ultrasonic thickness gauge determines the thickness of a part or structure by

accurately measuring the time required for a short ultrasonic pulse generated by a

transducer to travel through the thickness of the material, reflect from the back or inside

surface, and be returned to the transducer. The measured two-way transit time is divided by

two to account for the down-and-back travel path, and then multiplied by the velocity of

sound in the material.
