Product overview: Fluke 17B+ Digital Multimeter

Fluke quality is always within your reach

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. 

The CAT III 600V safety rating provides peace of mind for everything from routine checks on electrical equipment and appliances, to checking voltage levels at power outlets or switches, to diagnosing issues with circuits. If you’re looking to build out your toolkit as a DIY enthusiast or early career electrician, look no further than the Fluke 17B+ Digital Multimeter, a reliable and versatile tool that provides the essential features you need.

Specifications: Fluke 17B+ Digital Multimeter

Accuracy Specifications

Accuracy is specified for 1 year after calibration, at operating temperatures of 18 °C to 28 °C, relative humidity at 0% to 75%. Accuracy specifications take the form of: ±(% of Reading + Number of Least Significant Digits).

2Typically, open circuit test voltage is 2.0 V and short circuit current is <0.6 mA.
3Specifications do not include errors due to test lead capacitance and capacitance floor (may be up to 1.5 nF in the 40 nF range).
4Typical means when the frequency is at 50 Hz or 60 Hz and the duty cycle is between 10% and 90%.
