日本aandd公司AD-3253/AD-3253B超声波测厚仪的英文介绍：
AD-3253/AD-3253B Ultrasonic Thickness Gage
Designed for Light Gage Materials
0.8mm to 200mm with 0.1mm Accuracy
Low Cost & High Technology
The AD-3253 Ultrasonic Thickness Gage uses ultrasonic waves to determine the thickness of a wide variety of solid objects from metals to plastics.
It is comprised of the digital instrument that controls the operation and a probe that transmits and receives the ultrasonic waves.
Features
. Compact and Light Weight
With a weight of only 180g, the AD-3253 is easy to carry and easy to use. Its light weight allows hours of fatigue free operation.
. Easy to Operate
Simply calibrate the AD-3253 to the material to be tested, place the probe on the test material and the AD-3253 automatically
displays the correct thickness. No special qualifications or training are required.
. Easy to Read LCD Display
Displays both measured thickness and sonic velocity of the sample.
. Sonic Velocity Stored into Memory
Sonic velocities are easily entered into the AD-3253 unit through simple up and down keys. When a new entry is made, it replaces
the previous entry and stores the new one until changed, even if the unit is powered off or the battery is changed.
. Low Battery Indicator
Low Battery appears when the battery is low, after which the operator has one hour of operation before battery replacement is required.
. Able to determine unknown Sonic Velocities
Simply calibrate the AD-3253 against a known test block and place the probe on the sample material of the same thickness.
One button operation sets the unit to the proper thickness and the AD-3253 automatically enters the correct sonic velocity.
. Selectable Units of Measure
When performing thickness measurements, the operator is able to easily select between inches or millimeters units of measure.
. Automatic Power Off Function
The AD-3253 operates continuously for more than 30 hours off of one AA alkaline battery (25", 5 mm sample thickness) and,
automatically powers off the unit after 5 minutes of non-use, substantially extending operating life between battery changes.
. Applications
Thickness Measurement, Corrosion Test, Inspection
. Samples
Steel, Cast iron, Titanium, Aluminium, Copper, Brass, Glass, Ceramic, Plastic, etc.
Standard Accessories
Soft carrying case
5mm thickness test block
