美國DAKOTA VX手持式超聲波聲速測定儀|VX球化率儀|VX聲速儀

DAKOTA公司VX是一種手持式超聲波聲速測定儀(球化率儀)。當(dāng)被測定的材料是鑄件、合金或者塑料時，VX球化率儀就會測出聲波穿過它們時的速度。因此，可得出所測材料內(nèi)部組織是否緊密無缺陷。 如可預(yù)先將球墨鑄鐵不同球化率百分比(通過金相法)試樣做出，分別測量其不同的聲速值，然后和實際工件的聲速值進(jìn)行比較，以此判斷球化率情況。用于對鑄件進(jìn)行批量檢查。
 

With the hand-held VX Ultrasonic Velocity gauge, you can determine material velocities by measuring a known thickness, entering a known thickness into the VX, and the material velocity will be displayed. The tool’s backlit display is easy to read, even in dim light, and the unit operates for up to 200 hours on a single set of batteries.

The VX comes complete, ready to use and is protected by Dakota Ultrasonics 5 year limited warranty.
