Features and Benefits of the Fluke 325 Clamp Meter
Let’s dive in and see if this circuitry tester has sufficient capacity and features for the pro operative.
Capable of investigating heat levels from 14 degrees through to 752 degrees Fahrenheit via an included Type K thermocouple — the 325 Fluke is ideal for addressing HVACR (heating, ventilation, air-con, and refrigeration) systems.
This separates the unit from its close cousin, the 323, which doesn’t possess temperature testing. Furthermore, European users may appreciate that with a quick press of a button, the display will switch from Fahrenheit to Celsius.
CAT IV Safety Rating
Harcore contractors need an extreme testing machine when dealing with high energy loads. Therefore, it’s pleasing to see that the 325 from Fluke boasts CAT III (600 volts) and CAT IV (300 volts) safety ratings.
This permits the unit to be safely operated in conjunction with three-phase systems and mains utility cables, transformers, and distributors — crucial for the commercial user.

If you’re a busy trade pro — you have a lot on your mind. The last thing you want is to try and memorize your meter readings for later investigation and scrutiny. Hence, it’s rewarding to discover that the Fluke Clamp 325 features Hold, Min, and Max functions.
The memory hold stores your most recent reading on the generous LCD display, while the Min and Max systems detail the peaks and troughs encountered during your analysis.
The Fluke Multi Clamp Meter 325 promises impressive versatility in circuit testing. In addition to the temperature checking facility mentioned earlier, this unit can also deliver results on:
- AC and DC current.
- AC and DC voltage.
Furthermore, with in-built TRMS (True Root Mean Square) technology, the meter boasts greater accuracy than its standard RMS competitors.
Generous Backlit LCD Screen
The design boffins at Fluke understand that electrical testing jobs can take the electrician into some poorly illuminated environments — such as basements, attics, and beneath floorboards.
Hence, with this in mind, they not only included a large-digit substantially-sized display for effortless reading — but also a backlit screen to permit use in dim locations. This also negates the need for a secondary work light — which can be awkward to utilize in areas where space is at a minimum.
Weighing just 9.89 ounces and measuring 8.14 x 2.95 x 1.33 inches — this is a pleasingly slimline and compact clamp meter. Not just promoting effortless portability and transportation, it also permits the unit to access tight spaces, such as inside air-conditioning housing.
Large Jaw Opening
Squeezing the large, tactile, side-mounted trigger of the Fluke Meter 325 opens the clamp jaws — up to a maximum of 1.18 inches. This allows you to investigate the voltage and current of significantly proportioned wires, such as underground and reinforced cables.
Ample Selector Dial
A considerably proportioned selector dial, together with its easy-rotate operation, permits you to effortlessly switch between analysis metrics — whether wearing gloves or using one hand.
When you purchase the Clamp Meter 325 from Fluke, you don’t just receive the base testing unit.
Arriving with the circuitry tool are:
- Type K temperature testing thermocouple.
- Probe leads.
- Probe tip protectors.
- Instruction manual.
- Padded carrying case.
- 2 x AAA batteries.

What Do Users Say About the Fluke Clamp Multimeter 325?
For me, the 325 clamp meter is a pro-grade unit that will meet the requirements of light-to-medium contractors and serious amateurs. Premium-priced, yet offering the precision and durability concomitant to the brand — the machine promises reassuring reliability even with intense use.
However, I’m not utilizing this circuitry tester on a day-to-day basis — unlike hardcore electricians. Therefore, to guarantee the most accurate review possible, I sought the opinions of 325 owners — to reveal exactly how this tool stands up to extreme operation.
The views expressed were positive, and in most circumstances echoed my own feelings. Operators of the Fluke 325 appreciated the CAT IV certification, welcomed the memory function, and applauded the backlit LCD screen.
Naturally, there were a few disgruntled operatives.
One trade electrician indicated that the temperature testing function limit of 752 degrees Fahrenheit was too low for their HVAC requirements. Furthermore, a downbeat DIYer considered the machine to be seriously hard on the pocket — with comparable units available at half the price.
That said, all owners concurred that the Fluke Clamper 325 was a solidly built and trustworthy meter for the genuine pro.
Alternatives to the Fluke Clamp 323
If you’ve made it this far in this 325 Fluke Clamp Meter review, and you’re still not convinced that this electrical tester ticks all your circuitry boxes — stick with me.
Knowing that it will not be ideal for all users and project types, I’ve sourced some alternative machines that may be more applicable to your demands.
The 323 hails from the same brand, and, like the 325, boasts TRMS tech, CAT III and IV safety ratings, and a memory hold feature. However, it omits some of the lesser utilized features of capacitance and frequency — abilities of the 325.
- Unlike the 325, it cannot measure temperature.
- Lacks the backlit screen of the 325.
- Significantly lighter on the pocket than the 325 machine.
The CL800 has an impressive heat investigation range of -14 degrees to 1000 degrees Fahrenheit — giving you more scope than the 325. That said, the Klein Tools machine offers a comparative CAT IV rating and TRMS technology.
- Easier on the wallet than the Fluke.
- Boasts non-contact voltage detection, not featured on the 325.
- Low-impedance to eliminate ghost voltages — not possible with the Fluke.
If you’re a serious DIYer looking for a feature-packed clamp meter, but the premium price point of the Fluke is a dealbreaker — consider this more affordable unit from Extech instead.
Like the 325, the MA445 includes temperature testing, a backlit LCD screen, TRMS tech, and memory functions. However, in the sub-$100 bracket, I suggest it will be more appealing to non-pros than the Fluke model.
- Measures temperature, not possible with the Fluke.
- Like the 323, boasts TRMS technology.
- Low impedance to eliminate ghost voltages — not possible with the 323 model.
Temperature testing permits the machine to be utilized in HVAC application, while its substantial jaw opening allows the scrutiny of wide diameter wiring. A generously-sized backlit LCD screen offers effortless reading in dimly lit conditions, and its CAT III and IV ratings mean the meter is suited to industry-grade systems.
For home users, the price may be a barrier. And, the lack of low-impedance and inrush filters may deter some hardcore tradespeople. But, for commercial operatives who demand function combined with durability — I suggest taking a look at the Fluke 325.
