Features

Includes NIST Traceable Calibration Certificate
Includes both Pulse-Echo Mode (Pit & Flaw Detection) and Echo-Echo Mode (Through Paint & Coatings Mode)
Using the standard probe T-102-2700, the gauge will read thru 0.040" coating thickness (1 mm)
Using one of the optional probes T-104-2700, the gauge will read thru 0.075" coating thickness (1.9 mm)
Calibrate to a sample of known thickness which automatically calculates the optimal acoustic velocity
2-Point Calibration to optimize linearity over a wide measurement range, automatically calculates the optimal acoustic velocity
Scan mode, 100 readings/sec. Probe is slid over a large measuring area, the minimum thickness during the "scan" will be displayed
Adjustable GAIN in 5 steps to fine tune the gauge for use on challenging materials or applications
Differential mode, Hi-Low Alarms with audible and visual indicators
User-selected Manual or Auto Zero of Transducer
The extruded aluminum housing is impact-resistant and environmentally sealed (IP 65)
to provide trouble-free operation under the toughest field conditions
Special-purpose probes are offered for a variety of applications (1 to 10 MHz)
Selectable Backlight ON/OFF/AUTO
