TI-25S Ultrasonic Wall Thickness Gauge
The TI-25S Ultrasonic Wall Thickness Gauge is no longer available and has been replaced by TI-25SX.
Click here to see the TI-25SX.
If you reguarly have to test a limited selection different materials the TI-25S is the ideal product for you. It contains 8 velocities of the most common materials (see complete List of Materials below) and two velocities that the user can define by using a simple software program.
The TI-25S has an easy to read backlit display, even in dim light, and the unit operates for up to 200 hours on a single set of batteries.
The TI-25S comes complete, ready to use, and is protected by our 5 year limited warranty.
Velocity Settings
8 preset velocities and 2 custom velocities on the TI-25S allow the user to customize it for specific applications, or to tune the calibration to be optimized for a specific type of material. Each time the "MATL Key" is pressed the velocity will toggle from one to the next in a circular pattern.
The preset velocities are as follows:
- 1. Aluminium 2024 (6375 m/s )
- 2. Stainless Steel 303 (5664 m/s)
- 3. Steel 4340 (5918 m/s)
- 4. Cast Iron (4546 m/s)
- 5. Plexiglass (2692 m/s)
- 6. PVC (2387 m/s)
- 7. Polystyrene (2337 m/s)
- 8. Polyurethane (1778m/s)
- 9. Custom 1
- 10.Custom 2
Note: To define the Custom 1 & 2 options, the free PC software needs to be downloaded to the gauge using the optional data cable (p/n N-306-0010)
- Multi-function 4.5 digit liquid crystal display with 0.500 inch numerals, backlit for use in poor light conditions.
- Measures from 0.025 to 6.000 inches (0.60 to 150.0 millimeters) switch to select English or metric units.
- 8 pre-set velocities and 2 custom velocities
- Measurements displayed in inches, nches/microsecond, millimeters, and meters/second.
- Four readings per second for single point measurements
- Ability to change between velocities without the use of computer software
*Note: If the Custom 1 and 2 are needed, they are set using the PC software (free) and downloaded to gauge using the data cable (optional, p/n N-306-0010)
