NDT（非破壊検査器） 超音波厚さ計
AD-3253/AD-3253B中文介绍：AD-3253/AD-3253B超声波测厚仪
- 超音波厚さ計 AD-3253 / AD-3253B
シンプル操作 - 専門知識や熟練技術がなくても、簡単に厚さを測定することができます
- 自己診断機能
電源投入後ただちに、自動的に動作チェックを行います。 - 音速調整機能
音速不明のサンプルでも、同じ材質で厚さが既知の試験片があれば音速値を調整でき、その材質の厚さを測定することができます。 - オート・パワーオフ
約5分間以上使用しないと自動的に電源が切れ、電池の無駄な消耗を防ぎます。 - 音速のメモリ
音速設定値のメモリーをするので、電源を切っても設定値を呼び出すことが可能です。（電池を抜くと設定値を保持しない場合があります。） - 軽量・コンパクト
本体は片手で持てる大きさで、約180gと軽量です。 - 液晶画面表示
超音波厚さ計AD-3253、AD-3253Bは、金属腐食の検査からガラス、プラスチック、セラミックス等、 - 範囲にわたる材料の肉厚測定や検査に最適なローコストタイプの計測器です。
測定範囲2.0～200.0mmのAD-3253と、測定範囲0.8～100.0mmのAD-3253Bをご用意しております。

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.
Feature
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
