THICKNESS GAUGE METER TL – 25MXT| Faadtech

TI-25MXT Thru-Paint Ultrasonic Wall Thickness Gauge

The new CHECK-LINE TI-25MXT Wall Thickness Gauge 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.

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 nodularity 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 can be used with any of the following hi-damped dual-element transducers specifically designed for use with E-E Thru-Paint Mode.

Measuring Range on Steel (with standard T-102-2700 probe)

Pulse-Echo (PE) Mode (Pit & Flaw Detection) – 0.040 to 8.00 inches / 1.00 to 199.9mm
Echo-Echo (EE) Mode (Through Paint & Coatings) – 0.100 to 1.000 inch / 2.54 to 25.40 mm

Total Measuring Range (Probe Dependant)
Pulse-Echo (PE) Mode (Pit & Flaw Detection) – 0.025 to 36.000 inches / 0.63 to 914.4 mm
Echo-Echo (EE) Mode (Through Paint & Coatings) – 0.100 to 1.000 inch / 2.54 to 25.40 mm

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
- Resolution of 0.001 inch (0.01 mm)
