The Fluke 115 is for general purpose electrical and electronic test requirements, the Fluke 115 true-rms digital multimeter provides the perfect answer. Its simple operation, compact design and ease of use makes it perfect for quick verifications and field service use.

The Fluke 115 displays true-rms voltage and current readings with 6000 count resolution, tests diodes, frequency, continuity and capacitance and provides Min/Max/Average readings to record signal fluctuations. A large white LED backlight aids work in poorly lit areas. Its easy-open battery access door makes battery changes a snap.

Fluke 115 multimeters are independently tested for safe use in CAT III 600V environments.
