PTC® Miniature Spot Check® Surface Thermometers 675 Series

This instrument is designed to measure surface temperatures, especially where space is limited. The bimetal sensor comes in close contact with the surface to be measured, which provides the thermometer with a fast response time. The small size makes for minimum "heat-stealing" from a part or surface. A lazy hand (max pointer) is held by a magnetic clutch and indicates the highest or lowest temperature reached in a given period. It will hold this reading despite the vibrations and jarring of normal use and can be reset indefinitely.
