Extech Instruments 1 Getting Started About the TKG250 Wave The TKG250 is a portable, digital, handheld thickness gauge and is specifically designed to measure the remaining wall thickness of primarily steel structures.
TKG250 Ultrasonic Thickness Gauge Probe Zero When turning on the TKG250, the gauge does an automatic zeroing of the transducer thus eliminating the need for an on-block zero. It will also electronically zero the transducer upon power up and at a particular time during normal operation. This feature ensures the transducer is working in accordance with electronic zeroing procedures. This feature is particularly important on high temperature materials and when the transducer becomes worn.
