The Starr TGD-100 Portable Ultrasonic Thickness Gauge is a great all-round device for non-destructive thickness measurement of metals, plastic and many other common materials. 

The TGD-100 has the capability to measure the thickness of any solid composition materials that have a regular grain structure of which an ultrasonic pulse can be transmitted through. This is done using the pulse-echo method with a twin crystal probe (transducer). Such materials include:

  • Metals (steels, aluminium, copper, cast iron and more)
Plastic (HDPE)
Glass
Rubber (most types)
and more.
 
It has advanced features including a 2-point calibration mode for greater accuracy within a specific thickness range; low and high limit setting with alarm function for go/no-go testing; adjustable sensitivity (gain) for high attenuating materials (HDPE etc); 5 preset material sound velocities for quick user reference and an internal memory data-logger for recording groups of data (500 readings max. in 5 groups).
 
User calibration check and adjustment is carried out with an integrated 4mm calibration block located on the front of the unit. 
For 2-step calibration and NATA certification, an optional 4-step calibration wedge block (SW-1) is available for purchase separately.

  • Large, clear LCD with switchable backlight
  • 500 Reading internal memory
  • Export data to PC via USB -> mini USB cable (software included)
  • 2-Point calibration mode for greater accuracy
  • Alarm limit setting for minimum / maximum tolerance values
  • Automatic probe recognition with all LEMO 00 connections

PROBE OPTIONS:
 
The standard supply is a 5MHz right angle transducer (probe); and this is recommended for most applications. If you have difficult or non-standard application or material, then we offer additional options as follows:
 
Mini Probe (6mm right angle)
 
Used for curved surfaces with a diameter of at least 15mm the smaller surface area of the probe allows for better coupling with the curved material being measured.  This probe is also suitable for measuring thinner materials and in machined grooves and recessed areas.
 
 
2MHz (10mm right angle)
 
The 2MHz probe is for high penetration.  With a lower frequency and longer wavelength it is used to take readings on thicker samples and high attenuating material such as rubber and plastics including HDPE etc.
 
High Temperature (10mm straight probe)
 
The high temperature probe features a standard, straight 5MHz transducer wrapped in a thick Teflon grip designed to allow for safe, comfortable use whilst testing materials that are hot, up to a temperature of to 300°C; such as process pipe work and boilers. US of special high temperature coupling gel is also recommended for temperatures above 110°C.
