YUSHI UM-1 Series:Simplified and Precise Measurement
Product Overview
The UM-1 series of ultrasonic thickness gauges developed by YUSHI INSTRUMENT utilizes various dual-crystal thickness probes for thickness measurement of a wide range of metal materials. With accuracy and portable design, this handheld instrument provides fast, accurate and non-destructive readings and is an indispensable tool for material integrity assessment, corrosion monitoring and preventive maintenance.

About Thru-coating Technology
YUSHI is the first ultrasonic thickness gauge manufacturer that deveoped thru-coating thickness meters.UM-1D ultrasonic thickness machine has the capability of directly measure the net thickness of the material without removing or damaging the paint coating.
Normal thickness measurement mode measures the time difference T1 between the transmitting pulse and the first bottom echo (including the coating thickness). Through coating mode measures the time difference T2 between 2 continous bottom echoes.

What are the special features of UM-1 series?
- Through coating function(only for UM-1D)
- Modifying systematical errors by using the 4mm standard block on the instrument
- Data Logger:Up to 500 readings can be divided into 5 different material files for easy store and management
- Thickness restriction alarm: set the thickness limits and the value out of the limits will cause the alarm ringing.
- Minimum value scanning (MIN Capture mode): catch the minimum value during the measurement.
- 2-point calibration: Curve surface measurement or other special application with a high precision. thickness units of mm and inch. different velocities can be stored. The calibration value can be stored automatically without loss after turning off the gauge.
- Low voltage warning function.
- Backlight: Bring convenience to night working.
- Delete: The skeptical data in the file or the whole file can be deleted, so that new data can be stored.
- Automatic shut off: Five minutes without operating.
- Language: English and Chinese.
- Coupling state identification: The stability of coupling can be aware by the coupling mark.
