Kaiweets HT208D Digital Clamp Meter Review Summary

The Kaiweets HT208D is an affordable clamp meter that would suit professionals, mechanics, and hobbyists alike. It combines user-friendly features for newcomers to testing with more complex measurements for the experienced electrical scrutineers.
It includes multiple functions — checking 100A AC/DC current, 1000V AC/DC voltage, resistance, temperature, and more. And, this clamp meter also boasts a number of advanced features that make it stand out in its category, like True-RMS, and inrush current.

The device also comes with test probes, a thermo-couple for measuring temperature, and a clamp for checking live wires. Additionally, it has a built-in flashlight and permits the detection of live wires without using a probe (NCV).

With a rugged design, a ribbed silicone frame, and a spring-operated clamp mech, the HT208D is easy to hold and operate.

Kaiweets is a Shenzhen-based manufacturer — founded in 2018, it has rapidly grown to become one of the leading names in the electrical testing industry. Clamp meters aside, the brand also manufactures multimeters, voltage testers, and laser measuring equipment for contractor use. The HT208D is Kaiweets’ top-of-the-line clamp meter.

Features and Benefits of the Kaiweets HT208D Clamp Meter

The Kaiweets HT208D packs in plenty of features at a reasonable price point. Let’s take a closer look.

Inrush Current

The HT208D features an inrush current function. This helps you keep electrical systems efficient and safe by monitoring the initial surge of current a load draws when powering on. In short, it establishes whether it’s using more power than it should be.

This feature quickly identifies any issues with the starting circuit or load and accurately measures the inrush current in just 100ms. Doing so — prevents electrical failures, improves reliability, and enhances safety.


Clamp meters are either equipped with RMS or True-RMS (root mean square) measurement technology. The latter provides a far more precise reading than RMS.
Hence, this could prove invaluable if you need to avoid ‘best guesses’ in heating or air conditioning systems, computers, or other modern tech. Admittedly, for the casual tester, it won’t be so crucial, yet if you’re obsessed with accuracy, this will appeal.


The Kaiweets digital clamp meter offers a versatile range of functions for measuring:

  • Resistance.
  • Capacitance.
  • Diode and continuity tests.
  • Temperature — Celsius and Fahrenheit.
  • AC/DC current.
  • High/Low impedance.
  • AC/DC voltage.

You can also take advantage of auto-ranging. This is where the device picks the most suitable range according to the measurement you’re taking — ideal if you’re still learning the clamp meter ropes. The HT208D automatically selects auto-ranging unless overridden.

However, if you’re a little more experienced in the testing field, you’ll appreciate the RAN function. This allows you to select the range of your choice by manually cycling through them.

NCV Detection

You don’t need me to remind you that testing electrics doesn’t come without safety precautions.

Thanks to the NCV — aka non-contact voltage — detection function, you can check for electrical current without hooking up any probes. It’s dead handy for when you’re not quite sure whether the circuit is live or when you need to track its location within walls.

Rugged Design

The device’s rugged design offers both durability and ease of use. The ribbed silicone frame ensures a secure grip, while the spring-operated clamp mechanism makes opening and closing the device effortless.

These features make the unit less prone to damage and more user-friendly, reducing the risk of it slipping out of your hand. It also means that the device can withstand daily use and maintain its functionality.

Memory Function

When troubleshooting or performing maintenance, you’ll want to be aware of changes in the system. The HT208D permits you to store current readings as reference points, by way of a memory function — allowing you to compare current to previous readings. This saves you the hassle of either having to remember or routing around for a pen and piece of paper.

CAT III and CAT IV Safety Rated

The Kaiweets carries both a CAT III (1000V) and CAT IV (600V) safety rating. This means that this unit can handle testing anything from home appliances up to the seriously pro-grade mains connections.

What’s Included

You can use the HT208D digital clamp meter straight from the box. This is what you’ll find inside:

  • Clamp meter unit.
  • Thermocouples (k-type).
  • Carry case.
  • A pair of test leads.
  • 3 x AAA Batteries
  • Instruction manual.

What Users Say About the Kaiweets HT208D

For me, the Kaiweets has some pretty impressive features for both the newbie and the experienced pro — and the price is something to smile about too. However, that’s just my point of view.

What do users have to say about it?

Many rave about the device’s solid build and design, praising its sturdiness and durability. They also applaud the color display, stating it makes it easy to read the measurements and navigate through the device’s various functions.

Additionally, the integrated NCV detector was a major plus for operators, determining the presence of voltage swiftly. The device’s advanced features, like the inrush current testing and low Input Impedance modes, were also highly appreciated for their ability to provide even more precise readings.
However, a few moaned that while it’s a sturdy device, it’s a touch heavy.

Alternatives to The Kaiweets Digital Clamp Meter

Not everyone will find the Kaiweets HT208D the ideal fit for their requirements — and I get that. So, I’ve scoured the market and picked three alternatives that may be better suited.

Kaiweets HT206D Digital Clamp Meter

If you’re happy with the brand, yet you’re not bothered about inrush current testing, you may wish to consider the Kaiweets HT206D.

It offers many of the same features as the HT208D — 6000 count display, True-RMS, NCV, and temperature measurements. Plus, functions like resistance, capacitance, and continuity testing.

However, it’s safety rated for CAT III (600V), unlike the HT208D that’s capable of testing CAT IV.

  • HT206D has a lower price point compared to the HT208D.
  • Weighing 9.1 ounces, the HT206 is lighter than the HT208.
  • Both include a pair of test leads and temperature probe.

Check Out the Extech MA440


The Extech MA440 is a budget-friendly alternative to the Kaiweets HT208D. It offers a range of comparable features such as AC/DC voltage, current, resistance, continuity, and diode tests.

The MA440 also has a 4000-count LCD display, True-RMS, NCV, and temperature measurements. Its 1.18-inch jaw size opens wide to accommodate conductors up to a whopping 500MCM, making it a worthy adversary.

However, it doesn’t include inrush checking, a standout feature of the HT208D.

  • The Extech MA440 is more pocket-friendly than the HT208D.
  • Both have an auto-ranging capability and a data hold function.
  • The MA440 has a larger display compared to the Kaiweets HT208D.

Klein CL600 Digital Clamp Meter

If you’re looking for something a little less bulky and not so weighty as the Kaiweets, the Klein CL600 digital clamp meter may appeal.

The CL600 also offers similar functions as the HT208D, such as AC current measurement, AC/DC voltage, resistance, continuity, and diode testing.

However, unlike the HT208, the CL600 lacks the handy feature of a LED flashlight for dimly lit areas.

  • The CL600 is a touch lower in price compared to the HT208D.
  • Weighing 11.8 ounces, the Klein is lighter than the Kaiweets.
  • Falls short in inrush current measurement, a feature the HT208D boasts.


The HT208D Clamp Meter is a fantastic option for those in the market for a reliable and cost-effective device. Not only does it offer a wide range of measurement capabilities, including the ability to measure inrush current, NCV detection, and more, but it also boasts a user-friendly design.

Admittedly, for the novice tester, this clamp meter may be overkill for advanced functions. Yet, given the pleasing price point, it’s certainly worthy of consideration. So why wait? Check out the Kaiweets HT208D.
