Extech TKG250

General Specifications

Alarm

Audible beeping; illuminae flashing display and keypad; and vibration feedback

A-Scan (Live Waveform)

Full adjustments for gain in 1dB step or AGC, main bang blank, blank after first received echo, range including zoom auto tracking to center echoes independent of material and rectification

B-Scan (Cross Section)

Displays a visual cross section of inspection area with no correlation to distance

Differential Mode

Displays the difference from the actual thickness measurement and a user entered reference value

Echo to Echo

Measure the metal thickness only (paint and coatings do not affect base material thickness value)

Gain

In 1dB steps from 20-90dB or Automatic Gain Control (AGC) for waveform

Material Velocity Calibration

0.200 to 0.7362 in/µS (0.508 to 18.699mm/µS)

Memory

Stores 50k readings (expandable to 100k) and 5,000 waveforms

Rectification Mode

RF, Half Wave Positive, Half Wave Negative and Full Wave Rectification

Steel Thickness

5MHz probe: 0.040 to 20" (1.0 to 508mm); 10MHz probe: 0.030" to 2" (0.76mm to 50.8mm)

Velocity Mode

Displays acoustic sound speed to measure thickness of unknown materials
