PTC® Direct Contact Thermometer with Magnetic Leaf Spring 50° to 500°F #572FM

Direct Contact Spot Check® Surface Thermometer with Magnetic Leaf Spring 50°F to 500°F 

All Spot Check® thermometers come with a spring lifter knob to enable the user to safely remove the instrument from a heated surface. The knob is threaded and attaches to the center post of the thermometer. The instrument’s bimetallic coil directly contacts the surface to be measured. In response to temperature, the sensor expands or contracts, causing the dial itself to rotate.
