Magnetic Field Indicator (Burmah-Castol)

The Burmah-Castrol Magnetic Field Indicator is a thin, flexible test strip designed to provide visual indications of magnetic fields in non-destructive testing (NDT) applications. It consists of three precision-engineered layers, each 0.05 mm thick:

• The middle layer is made of a nickel-iron alloy with high relative permeability, ensuring sensitive magnetic response.

• The outer layers are non-magnetizable, providing protection and durability.

The middle layer features three parallel slots, 42 mm long, evenly distributed across the width of the strip. These slots react to applied magnetic fields, producing visible indications that help assess field strength and distribution.

The Burmah-Castrol Magnetic Field Indicator is available in two versions: Type I and Type II.
