The Starr TGR-1000 Ultrasonic Thickness Gauge is suitable for users with basic requirements to measure the thickness of common materials such as metals, plastics, glass; but without the need for data recording and reporting.
- Easy to use, point-and-shoot testing
- Preset material sound velocities are programmed for user selection
- Integrated user calibration block
The TGR-1000 Thickness tester is designed with a metal body casing to help withstand the punishing conditions of workshops and industrial sites.
A 5MHz frequency, 8mm right-angle transducer (probe) is supplied as standard and is suitable for the majority of testing purposes.
There are also optional transducer probes available - see below
Ultrasonic thickness gauges work by using a sound wave pulse sent from the transducer (probe), through the material, which echoes off the back wall of the object being measured. The gauge measures the time it takes to receive the sound wave pulse back. Based on the material velocity of the object (how fast sound waves travel through a material), it then calculates the distance travelled. The distance travelled, divided by two is the thickness.
* Please note this gauge is NOT suitable for testing epoxy waterproofing membrane

PROBE OPTIONS
Mini Probe
The mini probe is used for curved surfaces with at least a 15mm diameter which allows for better coupling with the surface being tested. This probe is also suitable for testing thinner materials. 5MHz, 6mm.
2MHz Probe
The 2MHz probe is low frequency and used for getting results on thicker samples and high attenuating material such as rubber and plastics. 2MHz, 12mm. * NOTE - TGR-1000 has no menu setting or compensation for different frequency transducers.
High Temperature Probe
The High temperature probe fitted with PTFE grip housing, allows for use of the probe on hot surfaces up to 300°C. 5MHz, 10mm.
