widely used for steel thickness gauge with ISO certificate
Product introduction:
Our plant development and production of the UM-1D ultrasonic thickness gauge ultrasonic pulse reflection principle according to the thickness measurement, when probe ultrasonic pulses emitted by the measured object reaches the interface material, the pulse is reflected back to the probe, accurate measurement by ultrasound wave propagation in the material time to determine the thickness of the material being tested.
Features:
1,Our factory development and production of UM-1D ultrasonic measuring instrument with a small, lightweight, simple, functional excellence.
2,Can be used with various double crystal probes in different sizes and frequencies.
3, Function of zero point calibration and two points calibration can correct the error of the system automatically.
4, With the given data of thickness, the sound velocity can be measured, so that the measurement accuracy can be improved.
5, Coupled with prompt, low voltage-tips on the screen.
6, EL backlight display function: for measurement in poor lighting environment.
7, Dump energy indicator function: to display the real time dump energy of the batteries.
8, Shutdown mode: manual and automatic shutdown features are helpful for battery saving.
9, Features of portable figure, high reliability, anti-vibration and anti-interference make it can be used in terrible operation environment.

Our factory also development and production of UM-5 color screen with A-scan feature allows users gauge can be seen directly on the screen, color ultrasound signal waveform (or A-scan), which need to verify whether the correct thickness reading is crucial occasions the. Many cases will lead to the wrong thickness readings or no readings, according to the waveform can easily find the problem, and then only on the waveform gain (GAIN), blanking (BLANKING), gate (GATE) to make appropriate adjustments to these three parameters, it is obtain the correct thickness readings.
We always put quality as the first consideration. So purchasing our product is your best choose!
