Why Buy the Fluke 179 Multimeter?

Let’s examine the main advantages of the Fluke 179 True RMS digital multimeter and how these features can help during everyday electrical work.

Durable Construction

If you’re looking for a digital multimeter that can withstand regular professional use, the Fluke 179 is worth considering.

Its rugged housing is designed for demanding work environments, while the rotary dial and buttons feel solid during operation. The meter is suitable for workshops, maintenance departments, and electrical service work.

However, you should always inspect the multimeter and test leads for damage before using them. Even a durable meter can become unsafe if its protective housing or insulation is damaged.

Easy-to-Use Device

Although the Fluke 179 offers several advanced functions, its controls are relatively straightforward.

The large LCD screen displays measurements clearly, while the backlight improves visibility in poorly lit working areas.

Its automatic ranging function selects the appropriate measurement range, reducing the need for manual adjustments. Experienced users can also choose manual ranging when needed.

The analog bar graph is another useful feature. It helps users observe rapidly changing signals that may be difficult to follow using numerical readings alone.

Designed for Electrical Safety

The Fluke 179 carries CAT III 1000V and CAT IV 600V safety ratings, making it suitable for a wide range of electrical environments within its specified limits.

Its input protection and safety-rated construction are especially useful for professionals who regularly troubleshoot electrical equipment.

However, safety ratings do not eliminate the dangers of electricity. Always follow proper electrical testing precautions, use appropriately rated test leads, and verify the meter on a known source before and after checking for the absence of voltage.

Never measure resistance, continuity, or capacitance on an energized circuit.

Easy to Carry

One challenge electricians face is carrying several testing instruments between job locations.

The Fluke 179 weighs approximately 420 grams, making it portable enough for everyday service work.

Its compact design allows it to fit inside most technician tool bags. A compatible protective carrying case can also be purchased separately if one is not included with your chosen package.

Versatile Measurement Functions

Many inexpensive multimeters perform only basic voltage, resistance, and continuity measurements.

The Fluke 179 goes further by offering capacitance, frequency, diode, and temperature measurements.

The built-in thermometer is particularly useful for HVAC technicians and maintenance professionals. With the included temperature probe, users can measure temperatures from -40°C to 400°C within the specified conditions.

This reduces the need to carry a separate thermometer for many routine troubleshooting tasks.

Accurate True RMS Readings

One of the biggest advantages of the Fluke 179 is its True RMS technology.

Unlike average-responding meters, True RMS multimeters can measure the effective value of many distorted AC waveforms within the instrument’s specified bandwidth and crest-factor limits.

This is useful when testing electrical equipment with electronic controls, switching power supplies, and other loads that may not produce clean sine waves.

The Fluke 179 also offers DC voltage accuracy as good as ±(0.09% + 2 digits), making it suitable for precise electrical troubleshooting.

Fast and Convenient Measurements

The Fluke 179 responds quickly during routine testing. Its digital display and analog bar graph help users monitor changing measurements without constantly adjusting the meter.

The Min/Max/Average recording function is useful when checking voltage fluctuations or monitoring a circuit over time.

Display Hold and Auto Hold can also make readings easier to record, especially when working in awkward positions.

Limited Lifetime Warranty

Another advantage of the Fluke 179 is its limited lifetime warranty.

Fluke provides warranty coverage for qualifying defects in materials and workmanship, subject to the manufacturer’s terms and exclusions.

This adds long-term value for professionals who depend on their multimeters regularly. However, the warranty does not cover every type of damage, misuse, or normal wear.
