Enclosed Ultra Magnetic Rail Thermometer -20° to 160°F

These fully enclosed ultra-magnetic surface thermometers are the toughest yet. The Models 550F and 555F are built using quality materials using the strongest magnet ever designed for a surface thermometer. The surface thermometers were designed specifically for the rail industry for checking rail temperatures prior to welding for determining gap size.

The Gauss rating for the magnet used in this unit is a minimum of 3400. Use care as the unit will snap to the surface when attaching to ferrous materials. The Model 550F and the 555F also feature an unbreakable plastic (Lexan) lens and a red pointer for quick and easy readings.
