fluke 107 digital multimeter review 2021

The Fluke 107 is a useful electronic multimeter that is super compact and smooth. Part of the Compact 100 series of ‘budget’ multimeters, it can do most of the full range digital multimeters including range current, capacitance and millivolts. It is an auto-ranging meter with a backlit screen and good section rating that comes with a magnetic strap.

In-depth Review of the 107

Although classified and recognized as pocket multimeters, the 107 bears somewhat larger when the tops are plugged in; Say, compare it to PM55A which is a true pocket multimeter. There is no milliamps / micro-amps range and since millivolts are only AC it is not really suitable for heavy electronics. It auto-ranges, although there are no manual limit buttons. This is not a problem for most work, perhaps to take a low, pendulum voltage. The continuity is fast enough and it has a latching, scratch-free beeper.

Build Quality

Like all flukes, the 107 is very well built. Like the 110 series, these models are made in China to reduce costs. It does not stop the quality with the help of dials and buttons, in any tough case. It is light and compact, fits well in the hand and has a combined plastic holster to keep the size down. This will provide less protection during drops. The interface is also raised so it opens up to the bangs. There is no built-in bail, but it can be folded into the stand by hanging the ships with the help of a magnetic strap. The probes are TL75 and are of flexible and decent quality, although they are quite long. The battery bogie is easy to find with the lock screw.

Interface and Function

The display is nicely backlit and 6000 times, which is updated three times a second. It is crisp and clean but can wash away when viewed from any angle. With the exception of resistance, continuity, and the diode tester – the rest is also clear with the dedicated dial position of most ranges. Select the frequency and duty cycle and the button is controlled with the hold properties. The buttons are rubberized and hard to the touch. Battery life is attempted at 200 hours. Using backlights can reduce this a bit. 

Battery/power down: The backlight will turn off automatically after a few minutes of inactivity. Auto power-off is set to 20 minutes.

Safety

The Fluke 107 is a large HRC-type, fast blow fuse rated at 11. This meter has only one fuse as there is no low current input. Input protection with MOV, PTC and current limiting resistors are just as great as any other fluke. It is rated at Kate-III @ 600V, so can handle 6 kV surges. The probes are rated CAT-IV at the same ground voltage.

Pros and Cons

PROS

  • Compact, nice feel
  • Solid build
  • Good input protection
  • Measures most ranges
  • Backlit screen
  • Fits in overall pockets

CONS

  • No manual rang
  • Not Min/Max
  • No low current input

Fluke 101 vs Fluke 107 – Digital Multimeter Comparison

The Fluke 101 and Fluke 107 are 10 *series digital multimeter. These are primarily intended for use by users or professionals as a backup multimeter. They will do their job well if used in the manner described in the previous sentence. These are not suitable for any kind of high demand use as they have only basic functions.

Fluke 101 multimeter vs Fluke 107 multimeter: Which one is the best?

I will compare the features of these multimeters with their price range and the types of uses they have in mind by designing them as they are both designed as general backups or primarily as multimeters.

Quality of build

In the case of multimeters, the quality of the build is very important because they need to be able to withstand severe forces and still be able to function properly without compromising all their functions. It comes with rubber shells on the outside or hard, more powerful plastic multimeters on the inside when it comes to multimeters but in most cases, the covering itself is made from strong plastic. People usually expect their digital multimeters to be hard and solid or at least have a hard rubber shell because the rubber is not very expensive. If a multimeter is light, a casing made of recycled plastic will work. Size is also important when the purpose of the multimeter is observed in context.

The Fluke 101 is a compact, lightweight multimeter that will fit perfectly in your pocket and your hand.

Although the Fluke 101 does not have a rubber shell on the outside, it was made from great plastic which will protect it quite well from low to medium damage. The outer shell can sometimes be slippery, so it can be bad if your palms sweat. The Fluke 107 digital multimeter is larger than the Fluke 101 digital multimeter, but it is still classified as a compact digital multimeter because it can fit in your pocket as well.

The Fluke 107 also has no rubber, but when you take it in your hand you can get a better feel for the thicker plastic cover in this case. These multimeters are not slippery, although they could do something to grab a little more.

WINNER: FLUKE 107

Accuracy

Accuracy is the most important feature when it comes to multimeter functionality. While it is unreasonable to expect the backup digital multimeters to have the true RMS feature, both of these digital multimeters are more accurate than other products in this price range. If you decide to get one of these multimeters, you can be sure that they will measure their things exactly as they should and you will be happy to read their output.

Fluke 101

This multimeter is sent with a manual that gives you detailed instructions on how to calibrate the Fluke 101. The Fluke 101 is accurate when first purchased, but its level of accuracy is at the level of other multimeters on the market in this range of prices. The accuracy will be set after setting the fluke standard.

Fluke 107

The Fluke 107 doesn’t need to be calibrated because it makes accurate measurements from the moment you buy it. As you decide to calibrate it as the manufacturer recommends, its level of accuracy will rise to the next level.

WINNER: FLUKE 107

Safety

This is a very important feature in the case of multimeters, but when it comes to multimeters that are intended for use as backup models, it can be neglected to a certain degree. Initially noticed models usually do not have any safety certificates like CAT III and IV and fuses are usually of poor quality but since Fluke manufactures these multimeters you can relax because they took care of everything.

Fluke 101

The Fluke 101 is CAT III certified up to six hundred volts but has no fuse. I understand the conclusion since it cannot measure amps but still, the manufacturer should have made a fuse because the fluke can measure 101 volts. If it breaks, you can replace or repair the Fluke 101 within one year of purchasing it after you have brought the warranty.

Fluke 107

Fluke 107 was made for use by electrical technologists. Unlike the 101 models, the Fluke can measure 107 MPa. The manufacturers have decided to make the fat in this multimeter, in addition to the CAT’s third certificate that can handle juice up to 600 volts.

WINNER: FLUKE 107

Ease of use

If one of these multimeters is used by the user as a backup, ease of use is no reason, but if they are purchased by new users who plan to use them for practice, this should be taken into account when making a decision.

When thinking about multimeters in the price range of up to a hundred dollars, customers generally expect that multimeters will be difficult to use because of the crammed features or simply, although these models have very few features. This is a reasonable expectation because most multimeters are like that. Instead of the Fluke model, it is.

Fluke 101

To cut straight to the point, the Fluke 101 can only measure basic features and is easy to use. I think this is great because manufacturers could easily try to further complicate these basic features to apply them to inexperienced buyers without being able to detect them in time.

Fluke 107

This multimeter is easy to use. While it has more features than the Fluke 101, such as backlight, hold setting, and frequency setting, the Fluke 107 is just as easy to use as the Fluke 101. This should initially apply to most of the applicants, as they will get more settings for ease of use at the same level.

WINNER: FLUKE 101

Roundup

The Fluke 107 review has a well-rated multimeter that fits nicely in the hand. It can measure most test ranges, including amperage and capacitance, but will not be the ideal tool for electronics. The build quality and leads are good and it has a backlit display, where the 101 is not. There is a very capable meter which has an alloy carrying case.
