Crack gauge Electropotential EPD-8

(Equipment / Material)
Model Number: ЭПД-8
Condition: New
Location or Storage Country: Russia
Service Engineering Support: Yes
Warranty: No
Price: Call for price
Description:
Designed to measure the depth of surface cracks on products made of carbon steel, both low and high alloy (including austenitic stainless). The principle of operation of the device is based on measuring the voltage drop that occurs at the edges of the crack, when current flows through the product in the direction perpendicular to the crack.
Overview:
