Fluke 115 vs. Fluke 117 True RMS Digital Multimeter Comparison Guide

Customers often ask about the differences between the Fluke 115 and 117 digital multimeters, as both 6000 count 3.5 digit Fluke meters offer exceptional features at an affordable price point. While your intended application should always be the determining factor in deciding which multimeter to purchase, the information below can help you decide which meter is right for you. A couple points to consider:

Fluke Considers the 117 an Electrician’s Digital Multimeter while the 115 is Intended for More General Testing

Basically, the Fluke 117 was designed for settings where accuracy is of the utmost importance – such as the electrical maintenance of operation-critical commercial facilities. The AutoV/Loz function “prevents false readings caused by ghost voltage”, and the VoltAlert feature allows for “go/no-go non-contact AC voltage detection”. The Fluke 115 does not offer this functionality as is better suited for verification testing in the field. Additionally, the 117 includes automatic selection of ac/dc volts, a feature not included with the 115.

Transcat Comparison: Fluke 115 vs 117 - Key Differences

Both Units are Tested Safe for Use in CAT III 600V Environments and are Otherwise Quite Similar

In terms of Voltage, Current, Resistance, Frequency, and Capacitance measurement, the 115 and 117 are identical. Both are safe for CAT III 600V environments and boast a basic DC accuracy of +/- .5%. The general appearance and weight are also nearly identical, apart from the AutoV/Loz and Volt Alert indicators on the 117.

Neither the 115 or 117 offer Temperature Measurement, Data Logging, or a Lifetime Warranty

For those advanced features check out the Fluke 87-5, 179, or 289 Digital Industrial Multimeters.
