Information about Corrosion and Electrochemical Instruments

Corrosion and electrochemical instruments use a variety of methods to detect and measure corrosion and electrochemical conditions in plant machinery, field equipment, batteries, fuel cells, colloids, and other solutions or systems. Typically, nondestructive test (NDT) equipment is used to detect internal corrosion and measure corrosion thickness. Specialized instruments are used to measure the corrosion rate and to monitor media and system conditions. The corrosion rate, which is often measured in mils per year (mpy), is the amount of metal weight loss over a unit time due to corrosion. Many corrosion and electrochemical instruments include probes, provide numeric displays, and feature data logging capabilities. Some advanced devices include alarms that indicate when readings are outside a range of values.

Products & Services Related to Corrosion and Electrochemical Instruments

Eddy Current Instruments

Eddy current instruments are nondestructive testing (NDT) devices that induce detectable eddy currents in conductive materials. They are used to detect flaws, determine thickness, inspect welds, measure conductivity, and sort alloys.

Flaw Detectors

Flaw detectors are nondestructive testing instruments that can detect or measure defects in raw materials or finished products.

Nondestructive Testing (NDT) Conductivity and Resistivity Meters

Non-destructive testing (NDT) conductivity meters and resistivity meters are devices for measuring electrical conductivity and/or resistivity of solid media to determine the characteristics of its constituent materials.

Nondestructive Testing (NDT) Equipment

Non-destructive testing (NDT) equipment is used to detect, inspect, and measure flaws, bond integrity, and other material conditions without permanently altering or destroying the examined part or product.

Nondestructive Testing (NDT) Material Testers

Non-destructive testing (NDT) material testers are devices, machines and equipment that are used to determine residual stress, alloy type, hardness, microstructure, elasticity, heat treatment and other material conditions without permanently altering or destroying the material being examined.

Ultrasonic Instruments

Ultrasonic instruments use beams of high frequency, short wave signals to inspect, monitor, and measure materials and components.

X-ray Instruments and X-ray Systems

X-ray instruments and X-ray systems use penetrating X-rays or gamma radiation to capture images of the internal structure of a part or finished product.
