The Fluke 177 and Fluke 179 are two popular digital multimeters in the Fluke 170 series. Known for their reliability, ruggedness, and precision, these models are favored by professional technicians for troubleshooting and maintenance tasks.
Quick Summary
While both models offer True RMS accuracy, a 1000V measurement range, and robust durability, the Fluke 179 includes a built-in thermometer for temperature measurements (-40°C to 400°C) and comes with a temperature probe. This makes the 179 more versatile, particularly for HVAC technicians or applications requiring temperature monitoring.
The Fluke 177, on the other hand, is perfect for general electrical troubleshooting, offering the same accuracy and ruggedness at a slightly lower cost, ideal if temperature measurement isn’t needed.
