Magnetic Developer
Sprague-Mag is a magnetic developer which permits the visual examination of the magnetically recorded data on such items as the mag-stripe on an ATM card, hotel card keys, Driver's licenses, currency, or credit cards.
A data sheet for our Sprague-Mag Magnetic Developer is available for download on our
Technical Library page.Uses include manufacturing quality inspections, field service troubleshooting, anti-fraud/security checks, and as an engineering prototyping tool. This developer is so versatile that if you are involved with any product associated in any fashion with magnetic recording, then the potential applications for this developer is limited solely by your imagination.
As with many virtually indispensable tools, the concept of this developer is simplicity itself. The formulation contains iron particles suspended in a fluid with a high and rapid evaporation rate. When the developer is placed onto a magnetic surface, the liquid evaporates and the magnetic particles orient themselves in accordance with the magnetic pattern on the surface of the material.
It is available with two different sizes of iron particles; regular, and extra. The choice of particle size is determined by your application and the density of the magnetic fields/information.
Sprague-Mag is rated
Environmentally Safe. There used to be a number of similar products available, but all of them used ozone-depleting CFCs to insure quick liquid evaporation. With the advent of US Federal regulations restricting the use of such chemicals, these other magnetic developers have disappeared from the marketplace.
Sprague-Mag does not contain CFCs, and fully complies with all US regulations on the use of ozone-depleting chemicals.
