The 6 Best Klein 400 AAC Clamp Meters (2023 reviews)

Klein Tools has been making feature-packed meter for years, thanks to a combination of clever design and high-end materials. This meter is the only one that will reliably give an accurate reading on a ground or a neutral wire. It measures ac current and ncvt via clamp and ac/dc voltage, resistance, and continuity via test-leads, and temperature with thermocouple. The temperature test is just a rough induction and has a2% swing over 0 to 100 degC. It is good for around the house. The no touch voltage detector is a bit too sensitive but that’s good if you are not a trained electrical person. It is easy to use and very useful for appliance service work. The auto turn off feature helps save battery life.

Why We Like This:

Nice to have an easy to use meter to grab and go
Good entry level product for diy electric work

Middle/economy model for lighter duty use, good for around the house

Best With Inrush: Fluke Capacitance Measurement

Buy on Amazon

The fluke capacitance measurement is suitable and reliable and fits well with your daily purpose. This is a well made and well designed DMM. It provides accurate readings when measuring linear or non linear loads, regardless of waveform. It is light and small so it does not take up a lot of space in your tool bag/box. It is designed to verify the presence of load current, ac voltage and continuity of circuits, switches, fuses and contacts.

The meter will display OL when measuring above 600V. It is easy to open and has lines marked on the clamp face to show where the wire should be located for the most accurate reading. It works very well with alternating current at low voltages. The hold feature comes in handy for over head measurements.

Why We Like This:

A nice backlight for the lcd display
Testing leads and a nice carrying case
Comes with a case, meter, thermocouple, and a standard set of probes

Best For troubleshooting circuits: Fluke Klein 400 AAC Clamp Meter

Best For Testing start: Ideal industries Klein 400 AAC Clamp Meter

Buy on Amazon

We know from years of feedback from readers, customers and amazon sellers, what most people want in a convenient and appropriate meter. The ideal industries klein 400 aac clamp meter is exactly that - it's a simple meter that hits all the right notes. There is an ideal continuity / voltage tester with vibration but it doesn't have all the features this does. It features a compact jaw design for reaching into tight spaces. It will test if the battery is reading full or low juice on it. It is lightweight and perfect for checking water well and amperage while the pump is running.

This will detect voltages through 70 to 600 volts AC. It also has manual settings. The meter emits a tone when checking for continuity, but does not vibrate when testing voltage or current. It is very accurate and extremely easy to use.

Why We Like This:

Dials to turn making it very easy to use
Well worth the accurate and simple application for all your trouble shooting needs
Good investment for long term

Best With Temperature: Klein Tools advanced HVAC Clamp Meter

Buy on Amazon

We know from years of feedback from readers, customers and amazon sellers, what most people want in a convenient and appropriate meter. The klein tools advanced hvac clamp meter is exactly that - it's a simple meter that hits all the right notes. The Klein Tools Cl440 clamp meter is an advanced hvac clamp meter with automatically ranging true root square (trms) for maximum accuracy. It allows simultaneous viewing of voltage and current measurements. The meter measures ac current, inrush current, ac / dc voltage, dc microamps, resistance, continuity, frequency, capacitance, temperature, diodes, and more. The backlight stays on til you shut it off, which is how it should be.

The beeper is actually loud enough to hear by older guys who've been too long in noisy environs, which a lot of meters can't boast about.
