Fluke 117 vs. 179: What is the difference?

Additional Measurement Options

Both the Fluke 117 vs. 179 are capable of measuring a variety of ranges, including voltage, capacitance, resistance, and frequency. This makes them ideal for a variety of general-purpose projects, but don’t represent the only needs that might arise in this sector. In some cases, additional features will be required in this category so as to fulfill your operational needs. Some of these features can be included with the integration of an external system, while in other circumstances, you will simply need to find a product that offers a more reliable function for the capacity in question.

One of the main reasons that the Fluke 179 is an attractive option for those performing light industrial tasks is due to its reliability regarding the range of options available with its measurements. Diode measurements, for example, are one of the features included with 179’s alternative that functions better as compared to the Fluke 117. The Fluke 179 also comes with an inbuilt thermometer, which can be a lifesaver if your work entails a lot of temperature measurements. Though the same objective can be accomplished with the Fluke 117, you will need to purchase an external accessory to accomplish this. The need for such a connection can significantly slow down the overall pace of your work.

Non-contact Voltage Detection

A popular feature that comes with the Fluke 117 is its non-contact voltage alert system. This is a particular feature that is extremely useful for people who work with a lot of live wires and perform multiple tasks related to electricity. This feature allows the user to determine whether a particular wire has a current running through it without having to make any sort of direct contact with the area. Instead, they can just simply let the device hover over the section involved, and a beep will alert them of the presence of a current. This can literally save lives when dealing with larger equipment. Handling electricity is an issue that should always be taken seriously in terms of safety, as a small mishap with heavy currents can lead to severe bodily harm. It should be noted that this is not a feature that is present with the Fluke 179 alternative.

Automatic Enhancements

Another aspect to take into consideration when it comes to the implementation of these tools is the ease with which a variety of functions can be completed. One of the main advantages of working with a digital platform is the varying automatic features that accompany some of their operations. Though both the 117 and 179 have manual and automatic options, the latter doesn’t always present itself in the same manner in all models.

Both alternatives, for instance, offer the automatic detection of frequency ranges (thus, you don’t have to select the AC/DC options manually). This means that once you have configured your device to the needed setting, all you need to do is connect the test leads to their different slots. The Fluke 179, however, also features an Auto-hold button that allows you to lock on to a stable reading when dealing with highly fluctuating inputs. This can be quite a timesaver when compared to using a filter to observe such readings instead.

True RMS Capabilities

Both the 117 and 179 feature True RMS software, which greatly enhances the accuracy enjoyed from the readings. This can be a highly essential factor in a variety of industries, with sectors such as HVAC maintenance and repair setting this standard as the acceptable norm for meters working in this sector. The inclusion of True RMS ensures that the readings provided are accurate by up to 0.5%. This feature also enhances the capacity of these devices, including the detection of ghost voltages that might occur during a reading. This distinguishing factor allows the devices to negate a large number of false positives produced. They are also capable of reading clean and distorted waves, which can be a big plus when dealing with nonlinear loading.

Quality and Viability

As mentioned earlier, all of the products from the Fluke multimeter line go above and beyond with regard to the quality on offer. It should be noted that looking at this aspect is not as straightforward as it seems. It’s essential that the value for money provided with a product is established when determining the overall quality of the item. Both the 117 and 179 exhibits great quality with their provisions, depending on your particular needs. The former (117) provides a great alternative for multipurpose use and is especially ideal when dealing with live wires and other electrical equipment. The 179, on the other hand, comes with a myriad of additional features – which arguably makes it the best option for light industrial work. It also comes with some options unavailable with its counterparts, such as the sufficient measuring of diodes, temperatures, and readings offered in Milliamps. These extra features have been slated as the main reason impacting the price difference between these two options.

Safety Ratings and Warranty

The last major factor that should be taken into consideration is the safety ratings of the devices, as well as the warranties on offer. One of the primary elements that prove the quality of Fluke multimeters deal with their adherence to the safety concerns implemented in their sector. Both the 117 and 179 boast official ratings in this category, with the latter a step ahead in this particular provision. The Fluke 117 features CAT III 600V safety ratings, which makes their use application for a variety of equipment and appliances around the house. The Fluke 179, on the other hand, comes with CAT III 1000V and CAT IV 600V ratings, which technically extends their potential application to light industrial purposes as well as DIY projects. It should be noted, however, that both are quite suitable for a range of fieldwork. Both devices also come with a three-year reliable warranty from the manufacturer.
