Difference/cut rate model
High/low limit alarm
The ultrasonic thickness gage uses dual element transducers for corrosion applications. It offers many basic features such as Min/Max Mode that measures and recalls the minimum thickness at a fast 20 readings per second, Freeze Mode to instantly capture critical thickness, and Zero Compensation, A-scan display for echo-echo measurement.
Measurements from one side
Ultrasonic thickness gages make instant digital measurements by transmitting sound into a material from one side, making it unnecessary to cut the corroded part.
Lightweight and pocket-size 
These handheld gages are small enough to fit in a toolbox or inside your pocket. They are ideal for quick inspections in hard-to-reach areas.
Color-coded keypad 
You can directly access many important measurement features for time-saving operation. Strategically located keys are grouped together by color for easy operation.
Large OLED display  
The large numerals make it easy to read thickness measurements.
