The tool's backlit display is easy to read, 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 
The TI-25S has 8 preset velocities and 2 custom velocities allowing 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 list of preset velocities are as follows:

1. Aluminum 2024 (0.251 in/µs )

2. Stainless Steel 303(0.223 in/µs )

3. Steel4340 (0.233 in/µs)

4. Cast Iron (0.179 in/µs )

5. Plexiglass (0.106 in/µs )

6. PVC (0.094 in/µs)

7. Polystyrene (0.092 in/µs)

8. Polyurethane (0.070 in/µs)

9. Custom 1

10. Custom 2

Note: If the Custom 1 & 2 are needed, they are set using the PC software (free) & downloaded to gauge using the data cable (optional, p/n N-306-0010)
