The Checkline TI-25MXT Thru-Paint Ultrasonic Wall Thickness Gauge is a precision instrument that accurately measures wall thickness and the extent of corrosion of all metals, ceramics, glass and most rigid plastics from one side. When operated in E-E Mode (Thru-Paint Mode), the coating is eliminated from the reading and the gauge will display only the thickness of the metal wall. Checkline TI-25MXT Features include Automatic or Manual Probe Zero maximizing accuracy, 5-position Gain Adjustment to help located the correct backwall echo and to penetrate the walls on sound-attenuating materials such as cast metals and thick materials. It also features Differential mode, Hi-Low Alarms with audible and visual indicators and Scan mode that captures the minimum thickness at 100 measurements per second (100 Hz). It also includes a special Velocity Mode to measure in terms of velocity for modularity testing. The gauge and probe have a protection rating of IP67, is impact-resistant and environmentally sealed to provide trouble-free operation under the toughest field conditions. The TI-25MXT is covered by a 5-Year Limited Warranty, CE-certified and is proudly Made in the USA.
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
