Product Introduction of DDC-II Point Corrosion Sounder

Point corrosion depth gaugeIt is a new type of measuring instrument that combines optics and electronic circuits. Its working principle is to use microscopic focusing method to make its surface and the bottom of the pit clearly imaged twice in the field of view of the microscope. The change in focal length is converted into electric quantity through a transmitter, and the pit depth value is directly displayed by a digital meter.

Instrument principle

The point corrosion depth gauge is a new type of measuring instrument that combines optics and electronic circuits. It mainly consists of four parts: frame, instrument box, optical microscope, and electronic circuit; Its working principle is to adopt micro focusing, which means that the surface and ground of the pit are imaged clearly twice in the field of view of the microscope. The change in focal length (displacement of the microscope) is converted into electricity through an electronic circuit, and a digital meter directly displays the pit depth value.

Technical Specifications

Measurement range: 0-5mm

Error: The error within the full range is less than 0.02mm

Voltage: 220VAC ± 10%, DC 9.6-12V

Used in environments without strong magnetic fields and high currents

Instrument maintenance:

The power supply used for the point corrosion depth gauge is dual-purpose AC and DC. The DC power is supplied by a battery and stored in the instrument's battery box. It is equipped with a charging mechanism and can last for more than four hours without being charged once (AC power should be used as much as possible in places with AC power).
