The Fluke General Purpose Test Probe is a Type-J thermocouple probe designed for insertion into air and non-caustic gases. With a 1-meter (39-Inch) lead, the 15.25 cm (6-Inch) stainless steel probe has a measurement range of -40 to 260 Degree Celsius. General Purpose Test Probe is sold as one item per package. Expand your testing capability or update your tools with test lead sets and kits. Designed for industrial, electrical, and electronic needs, the collections range from starter to master test lead selections. Because they are an integral part of the complete measurement system, worn or under-rated test leads can cause inaccurate readings and pose a serious shock or electrocution hazard if live wires are read as being de-energized. To avoid these risks, use the correct test probe for the application. Fluke Corporation is the world leader in the manufacture, distribution and service of electronic test tools and software.
