Ultrasonic Thickness Gauge TT-500
The new handheld TT-500 Ultrasonic Wall Thickness Gauge offers the ability to measure the wall thickness through paint and eliminate
coatings. It assures accurate measuring of wall thickness and the extent of corrosion of all metals from the outside.
Features
• A-Scan display for waveform verification
• Wide thickness range (0.75-508mm)
• Echo-echo mode to determine the distance excluding the coating between two echoes
• Min. and Max. mode
• Two Differential modes:
- Thickness difference between actual measuring and reference value
- % difference between actual measuring and reference value
• Manual gain adjustment/auto gain selectable
• Large backlit LCD display
