Experience the precision, durability, and safety of a professional-grade test tool with the Fluke 17B+ Digital Multimeter. With the Fluke 17B+, you'll have a rugged, portable tool that's designed to be used with one hand, even while wearing gloves. It provides all the essential features you need in a digital multimeter, from AC/DC voltage and current measurements up to 1000V and 10A, to comprehensive capabilities including resistance, capacitance, and frequency checks. It also comes standard with a type K thermocouple so you can measure the temperature of things like your refrigeration systems, heat exchangers, and line sets. The 17B+ also supports relative measurements which allows you to zero out a source reading so you can easily measure changes in things like voltage drop or temperature making it ideal for identifying and diagnosing issues.
