The TI-25S Ultrasonic Thickness Gauge is ideal for the person that tests a few different materials regularly. The TI-25S Ultrasonic Thickness Gauge contains 8 velocities of the most common materials (refer to complete list of Materials below) and two velocities that the user can set using a simple software program 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 Ultrasonic Thickness Gauge comes complete, ready to use, and is protected by our 5 year limited warranty. Velocity Settings The TI-25S Ultrasonic Thickness Gauge 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: - Aluminum 2024 (0.251 in/µs )
- Stainless Steel 303(0.223 in/µs )
- Steel4340 (0.233 in/µs)
- Cast Iron (0.179 in/µs )
- Plexiglass (0.106 in/µs )
- PVC (0.094 in/µs)
- Polystyrene (0.092 in/µs)
- Polyurethane (0.070 in/µs)
- Custom 1
- 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)
Features
- Multi-function 4.5 digit liquid crystal display with 0.500 inch numerals, backlit for use in poor light conditions
- Measurements displayed in inches, inches/microsecond, millimeters, and meters/second
- Measures from 0.040 to 6.000 inches (1.00 to 150.0 millimeters) switch to select English or metric units
- Four readings per second for single point measurements
- 8 pre-set velocities and 2 custom velocities
- Ability to change between velocities without the use of computer software
10 User-Selected Material Types
Each time the "Matl" key is pressed, the material type (calibration setting of the acoustic velocity) changes from one type to the other. The abbreviations, description and sequence is shown below. 
*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)
