Description

TKG100 Digital Ultrasonic Thickness Gauge by Extech

Extech offers Thickness Gauges designed in compact, handheld, rugged housing ideal for field use. The ultrasonic technology allows for non-destructive thickness measurements for primarily steel structures. Select models with digital thickness readout or live color waveform and datalogging function.

Features

Wide measurement range: 5MHz probe: 0.040" to 20" of steel; 10MHz probe: 0.020" to 20" of steel (optional)
Sunlight readable dot-matrix display with backlight
Multiple transducer options for high temperature and difficult to measure materials
Fast minimum feature to capture minimum thicknesses
On screen display of 8 languages
Splash-proof (IP54), high impact, compact housing
Sun light readable

Applications

Boiler Tubes
Pressure Vessels
Storage Tanks
Ship Hulls
Containers
Home Oil Tanks
Pipes
Steam Lines
Compressors
Shafts
Bridge Pins
Bond Inspection

Specifications

Size	5" (127 mm) (L) x 3" (76.2 mm) (W) x 1.25" (31.75 mm) (H)
Weight	8 OZ (.23 kg)
Thickness range	0.008 - 20 inches (0.20 mm - 508 mm), depending on material, temperature and transducer selection
Material velocity calibration range	0.200-0.7362 in/μS (0.508 -18.699 mm/μS)
Temperature	Gauge Operating: -4° F to 122° F (-20° C to 50° C) Surface temperature of material: Depending on probe used, from -5° F to 1000° F (-20° C to 537° C)
Battery life	Up to 200 hours (40 hours with backlight on)
Battery type	2 "AA" Alkaline
Display	128 X 64 Graphics LCD monochrome
Information displays	LOS, min, max, large reading while displaying min at the same time, velocity, zero, calibration, units, freeze, unfreeze, % battery life remaining, gain - low, std, high, echo-to-echo symbol (option)
Resolution	0.001" (0.01 mm), 0.01" (0.1mm)
Accuracy	Basic Accuracy is 0.004" but on clean smooth steel an accuracy of 0.001" is not uncommon. The more corrosive the environment, and pitted the surface under test, the closer to the 0.004" accuracy one can expect to be. As noted, a higher accuracy can be obtained when measuring on cleaner steel.
Probe recognition	Via pick list from a menu
Delay line zero measurement	Auto at power up with listed numeric value. Ideal for correcting delay line wear/curvature and for transducer acoustic drift at elevated temperatures
Package	Custom, splash-proof, high-impact plastic with rubber, illuminating keypad for go/no-go testing
Bandwidth	: 0.5-20 MHz (-3dB)
Units	English/Metric/Microseconds
Gain	Low, Standard and High for varying test conditions
Measurement rate	4/sec and 20/sec in fast mode
Differential Mode	Displays the difference from the actual thickness measurement and a user entered reference value
Alarms	Minimum/Maximum depth, vibralarm, audible/visual indications as well as keypad illumination
Illuminating keypad	F1 = Red, F2 = Yellow and F3 = Green for easy, go/no-go testing (Patent Pending)
Automatic probe wear indicator ( Transducer attendant)	Automatically informs the operator to replace the transducer (Patent Pending)
Ergonomics	User selectable left-handed or right-handed display changes via keypad (Patent Pending)
Backlight	Light Emitting Diode, On/Off or Auto ON based on valid readings or last key-press
Shut off	Auto, time out (after X minutes user programmable after no reading, loss of signal LOS, or no key press)
Scan mode	Displays minimum or maximum thickness value at 20 measurements per second (ideal for high temperature thickness reading and tracking the minimum depth alarm). Press Freeze to capture last valid minimum thickness readings prior to Loss of Signal (LOS), without reading the couplant upon lifting probe off the test piece
Carrying case	Custom molded pouch with wrist strap for either left- handed or right-handed operators (optional)
Shipping case	Hard plastic with high-density molded cut out for all accessories (optional)
Freeze mode	Freezes display
Hold mode	Holds display to retain last thickness reading in reverse video display
Standard TKG includes	Ultrasonic thickness gauge, DK-537 potted, 5 MHz 0.375 inch diameter, operational manual, cable, couplant
Warranty	Limited 2 year warranty
