Sigma 342 Ultrasonic Thickness Gage

•Auto calibration to assure the accuracy
•Auto linear compensation with advanced software program that enhances the precision by correcting the
non linear accuracy of transducer
•Usage of keypad for a quick adjustment for the sound velocity thickness and a quick recall to the stored data
•Coupling status indication
-Coupling icon displays if the coupling is accomplished or not. 10 thickness measurement storage and recall
function is available which facilitates the height work or working in abnormal area
•Sound velocity measurement
-Given thickness by a sample block to measure the sound velocity thus avoiding further calculation or consult table for sound velocity of different materials.
•Low battery indication
•Auto power off mode designed to conserve battery power
•More power off mode designed to conserve battery power
•Long life keypad for more than 10000 times key presses.

•Transducer choice: 10mm 2.5MHz Transducer,
                                      10mm 5.0MHz Transducer
•Display: 4-digital LCD display
•Minimum display unit: 0.1mm
•Working frequency: 5MHz/2.5MHz
•Measuring range: 1.2 to 220mm(steel)
•Minimum limit for tube measuring: 20*3mm(steel)
•Accuracy: +/-(1%H+0.1)mm, H denotes the measured thickness.
•Sound velocity range: 1000 to 9999 m/s
•Measuring sound velocity with a given thickness: measuring range:1000 to 9999
m/s. When the given thickness over 20mm,the accuracy is +/-5%; when the given
thickness less than 20mm, the accuracy is 1mm/H*100%.
