The PTC® Industrial Railroad Thermometers are designed to measure surface temperatures for continuous welded or jointed rails. These thermometers meet the criteria for the AREMA specification on track maintenance.
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 thermometers can be stored in your pocket or a belt pouch.
