Magnetic testing rods MTV
The stainless steel encased rare earth inspection rod MTV is designed to detect ferrous metals. The magnetic tube probe is used at scrap yards & recycling centers for the inspection of the collected non-ferrous metals, at critical control points (CCP) of the production lines etc.
How is the magnetic stick used?
Just insert the magnetic probe into the tested material in several locations and remove it slowly to check for ferrous contaminants on the magnetic tube probe. The very strong neodymium NdFeB magnets inside of the sorting tube can also detect even the finest ferromagnetic particles in plastic materials (such as plastic regrind and granules, crushed plastic materials, plastic crumb, rejected plastics etc.).
Cleaning of the magnetic testing rod
The magnetic probe is light-weight, easy to handle and can be cleaned quickly and efficiently by realeasing the catch and sliding out the magnetic inner tube (which causes the magnetic particles to fall away).
Dimensions of magnetic testing rods
The magnetic inspection rods are manufactured in diameters of 25 and 32 mm with a length of 400 mm, and in a diameter of 32 mm with a length of 1,100 mm. The length of the active magnetic part is 160 mm for both lengths.

The magnetic testing rod MTV is a handheld inspection tool for detecting ferromagnetic contaminants — typically when purchasing non-ferrous scrap or inspecting granules and regranulates in the plastics industry. Unlike the MTH, which has a tip for immersion into loose bulk material, the MTV is used for surface inspection or sweeping across freely accessible layers of material.
The MTV is fitted with neodymium NdFeB magnets with a flux density of 8,000 G and can capture ferromagnetic particles from as small as 1 micron. This allows it to detect even trace magnetic contamination that is invisible to the naked eye — making it a fast and effective tool for material intake inspections.
The MTV is manufactured in three versions: Ø25 × 400 mm, Ø32 × 400 mm and Ø32 × 1,100 mm. The active magnetic section is 160 mm long in all versions. The shorter rods (400 mm) are suitable for work in confined spaces and transport packaging; the longer rod (1,100 mm) makes it easier to inspect deeper containers and tanks without having to bend over.
The operator sweeps the rod across the surface or immerses it into a loose layer of the incoming material — scrap, chips or granules — and after withdrawal visually checks whether magnetic particles have been attracted to the active section (160 mm). The presence of attracted material signals magnetic metals in the sample and provides grounds for a complaint or repricing of the delivery.
The MTV has a telescopic design: pulling the handle slides the permanent magnets out of the stainless steel tube, and the captured metal contaminants then fall away on their own without direct hand contact. Cleaning is quick and hygienic — the rod is immediately ready for the next inspection.
The MTV is found in the plastics and rubber industry for inspection of regranulates and regrind, as well as in recycling, mechanical engineering, the ceramics and glass industry, the chemical and automotive industry, and the food industry — wherever magnetic metals in a material need to be verified quickly and without laboratory equipment.
