This cam action hold down clamp features a thermocouple probe that provides the clamping point and temperature measurement of the clamped object. The thermocouple probe can be adjusted for varying clamping forces and or object size and shape. The thermocouple probe is electrically isolated from the clamp. Clamp is ideal for multiple volumes of the same object or for a variety of different object shapes and sizes. The device can also be used for temperature monitoring of objects that are difficult to mount thermocouples to.
