Type K Surface Temperature Probe Surface probe is ideal for flat stationary surfaces such as molds, heating elements, integrated circuits, transistors and transformers. Very low sensor element mass enables fast response measurement time. Type K thermocouple temperature probes are commonly used with all types of industrial temperature controls and measurement equipment, and are compatible with Tenma handheld thermometers and digital multimeters that include temperature function. All are terminated with standard Type K plugs. Optional Transition Adaptor converts Type K plug to dual banana plug inputs for use Tenma Digital Multimeters having temperature function. Optional 3m Extension Cable provides additional probe cable length. Multiple extensions may be added together. Specifications: Dimensions: 5¾" (L) x ½" (dia) Sensor head diameter: ⅝" Maximum temperature: 752°F (400°C) Cord length: 36"
