Features and Benefits of the Klein CL700 Clamp Meter

It possesses a bold black and orange design and is available at an affordable price point — but does the Klein clamp meter CL700 possess sufficient versatility for the dedicated home user and trade electrician?

Time to dive into the features and discover whether this machine is a worthy multimeter or nothing but a short circuit.

Temperature Probe

Perhaps the most striking aspect of the CL700 Klein is that it boasts a temperature testing facility — rare in a budget-priced unit. This makes the machine ideal for HVAC engineers and automotive enthusiasts who need accurate heat readings in the course of their trade or hobby.

Checking temperature is effortless. Simply insert the compact heat-sensing attachment into the base of the unit, switch on the machine, and touch the thermocouple tip onto your target — the result will be displayed on the generously-sized backlit LCD screen.

Automatically, the CL700 defaults to Fahrenheit. But, for users of a more continental persuasion — just press the SELECT button and the reading will change to Celsius.

Able to check temperatures from -14 to 1000 degrees Fahrenheit — it’s suitable for inspecting condensers, heating elements, engine blocks, and apple pies.

Drop Proof

If you’ve used a multimeter before — you know you never have enough hands. Typically you require one for the positive probe, one for the negative, and one to hold the machine.

Admittedly, clamp meters make the process easier, permitting one-handed use. While this is fine for checking current — you still need wired probes for voltage, resistance, and continuity tests.

This means the machine is either grasped between your neck and shoulder or balanced precariously on a car engine or air con-unit — raising the risk of slippage and damage. Therefore, it’s pleasing to see that the robust build of the Klein Tools CL700 shields the unit from drops from a maximum of 6.6-feet — should accidents occur.

CAT IV Rated

Unlike DIY and home-use focused multimeters that are rated to either CAT II or III, the Klein CL 700 carries a CAT IV 600-volt safety certificate. This permits the machine to be utilized on hardcore electrical systems, such as three-phase industrial circuitry.

Hence, this elevates the Klein Tools C L700 into the trade-ready sphere — making it appealing to both pro users and experienced amateurs. If you’re a glutton for information and want to know more — check out my What Are Multimeter CAT Ratings 101.

Testing Versatility

Demanding DIYers and picky professionals will be pleased to know this clamp meter boasts the versatility to test anything electrical. In addition to the multimeter standard features of investigating current, voltage, resistance, continuity, capacitance, and frequency — it has a secret weapon, a low-impedance mode.

This raises the bar for budget-priced clampers, allowing the CL 700 Klein Tools to check for those annoying stray and ghost voltages.


While an affordable unit, the designers at Klein haven’t compromised price for precision.

Utilizing TRMS (True Root Mean Square) technology, the CL700 delivers greater accuracy than standard RMS machines. If you want to know more about how this works and what it means for your projects, take a look at my What Does RMS and TRMS Denote In Multimeters article.

Furthermore, this clamp meter possesses a welcome auto-ranging feature. This ensures that whatever you’re testing (voltage, current, resistance, etc.), you don’t need to know whether you’re in the tens, thousandths, or ten-thousandths of a unit — the machine will select the correct range.

This is a serious advantage for newbie users or inexperienced electricians who have no idea about resistance banding or internal capacitance — and functions as a pleasing downtime saver if you’re a pro, negating the need to be constantly resetting dials.

Included Accessories

Arriving with the Klein Clamp Meter CL700 are:

  • Thermocouple adapter.
  • Testing probe leads.
  • Carrying pouch.
  • 2 x AAA cells — batteries are included.

What Do Users Say About the Klein CL 700 Multi Clamp Meter?

In my opinion, the CL700 from Klein is a pleasingly-priced clamp meter that possesses sufficient versatility and accuracy for DIYers, pro-users, and HVAC engineers.

Yet, I’m not utilizing the machine on a day-to-day basis, meaning my experience of this unit is somewhat limited. Therefore, to ensure a full comprehensive Klein CL700 review, I sought the opinion of CL700 owners — to discover how this clamp meter really performs.

Reassuringly, guys using this unit shared a similar outlook to me and bestowed generally nothing but praise on this clamp meter. Appreciation was shown for its industrial-grade CAT IV rating, its useful temperature-testing facility, and its robust 6.6-drop-proof build.

Admittedly, a couple of guys delivered some negative feedback. One DIYer criticized the LCD screen, finding it difficult to read unless you face the machine directly head-on. Additionally, a trade user felt that it was heavy on battery drainage, especially when using the backlight.

However, all owners concurred that the CL 700 boasted an exceptional price-to-quality ratio with pleasing precision.

Alternatives to the Klein Multimeter CL700

It’s possible that despite the CL700’s noteworthy features, you feel that it isn’t quite right for your preferences or electrical projects. That being the case, below are three worthwhile alternatives that may be more appealing.

Klein CL600

If you appreciate the price and quality offered by the Klein brand but are seeking something a little more basic and lighter on the pocket — consider this machine.

The CL600 still hails from the respected Klein stable, but is available at a more budget price. It boasts similar functions to the CL700, including capacitance, voltage, and diode testing — but lacks a temperature function that may not be necessary for casual DIYers.

  • Lacks frequency testing, unlike the CL700.
  • Like the CL 700, it arrives with probes, a carrying pouch, and batteries.
  • Unsuitable for HVAC engineers, unlike the CL700.

Fluke 381

If you’re concerned that the Klein isn’t designed for use in confined spaces, such as inside car engine bays or between cooling pipes — check out this clamp meter instead.

The Fluke 381 boasts a removable and magnetic display. This permits you to position the LCD screen in the most suitable place for viewing, while you access the narrow and confined areas with the clamp or probes. Transmitting the info wirelessly up to a distance of 30 feet — you can even give the display to a friend or colleague to check the results.

  • Like the CL700, the 381 is rated for CAT IV 600 volts.
  • In contrast to the Klein, the Fluke has no temperature testing feature.
  • Significantly harder on your bank balance than the budget CL 700.

Fieldpiece SC680

If you’re something of a tech lover and fancy a clamp meter that can interact with your portable electronics — which the CL700 cannot — I may have the answer.

The Fieldpiece SC680 works in conjunction with the Job Link App (available on the Google Play and Apple App stores) — sending your testing results to your cell, tablet, or laptop. This enables you to effortlessly store the info for future scrutiny or forward it to work colleagues or clients.

  • Rated for 1000 volts — as is the CL700.
  • Boasts a CAT IV safety rating, like the Klein.
  • Premium price — unlike the budget CL700.


Easy on the wallet, demonstrating impressive accuracy, and incorporating a temperature testing facility — the CL700 is a solid clamp meter that should appeal to the serious DIYer, light contractor, and HVAC professional.

With auto-ranging and TRMS technology, it delivers reassuring precision without having to reset dials and metrics. Its CAT IV rating permits use in industrial three-phase scenarios, while a robust reinforced build delivers shielding against drops and knocks.

Sure, it’s not going to appeal to everyone. The battery drain can be disappointingly high when used for extended periods, and the probe leads can accidentally detach themselves from the main unit with a gentle tug.

But, if you’re seeking a heat testing clamp meter without a shocking price — I recommend considering the Klein CL700.
