Product information "Sauter TN GOLD 80 ultrasonic testing device for verifying the authenticity of gold, 0.75 to 80 mm / 0.01 mm"
The Sauter TN GOLD 80 is a handheld ultrasonic measuring device from the Sauter TN series for verifying the authenticity of gold. An external probe transmits ultrasound into the material; the device calculates the thickness based on the transit time. It is battery-operated and, at 150 x 74 x 32 mm, fits in one hand.
Authenticity testing of gold
The TN GOLD 80 detects foreign cores, such as those made of tungsten or lead. To do this, it measures the thickness using ultrasound and compares the result with the thickness determined using a calliper. According to Kern, foreign cores can be identified by the fact that the ultrasound behaves differently to that in pure gold. The supplied Sauter SSG software calculates the sound velocity in various alloys and compensates for known admixtures such as copper or silver. According to Kern, the method tests non-destructively through the entire test piece. A zero plate for adjustment is included.
Probe, range and measuring mode
The probe operates at 7 MHz, has a diameter of 6 mm and measures from 0.75 to 80 mm; the readability is 0.01 mm. The sound velocity ranges from 1,000 to 9,999 m/s; Kern specifies the measurement accuracy as 0.5 % of Max ± 0.04 mm. The TN GOLD 80 measures at a single measurement point; it has no scan mode.
Memory and data transfer
The internal memory can store up to 20 files, each containing up to 100 individual values. The unit is mm or inches. The device has a USB interface. The LCD display features 14 mm high digits. According to the data sheet, two AA batteries last for approximately 100 h.
Typical applications
- Jewellery industry: authenticity testing of gold for foreign cores
For thickness measurement on metals and plastics, the same series includes the Sauter TN material thickness gauges.
