Okay, let's break down the Fluke 323 and T5-600, and see if either fits your needs, and if there are other options to consider.

Fluke 323: Pros & Cons Pros



Current Measurement (AC)

This is its strength. If you need to measure current regularly, particularly AC current (which is common in household and many industrial applications), the 323 is a good choice. It uses a clamp meter, which is much safer and easier than breaking the circuit to insert a meter.

Accuracy

Fluke is known for its accuracy and reliability. The 323 provides good accuracy for general electrical work.

Simplicity

Relatively straightforward to use. Fewer functions means less chance of selecting the wrong setting.

Rugged

Built to withstand abuse, which is important in a work environment.

Price

Usually can be found under $200.

Cons



Limited Functionality

It only measures AC current, AC voltage, resistance, and continuity. No DC voltage, no capacitance, no temperature, no frequency. This can be limiting depending on your needs.

No DC Current

If you ever need to measure DC current (e.g., in automotive applications or some electronics), this meter won't do it.

No True RMS

While acceptable for measuring sinusoidal AC waveforms (like from the power company), it won't give accurate readings on non-sinusoidal waveforms that can be present in circuits with electronic devices (like variable frequency drives or dimmer switches). This is important if you are doing work with more modern equipment.

Fluke T5-600: Pros & Cons Pros



Open Jaw Voltage Measurement

A unique feature. It allows you to measure AC voltage without making metallic contact with the circuit. This can be very convenient and sometimes safer for certain applications (although you should ALWAYS de-energize when possible!)

Continuity

Standard continuity testing.

AC Current Measurement

Also has AC current clamp meter function.

Simplicity

Very easy to use. It's designed for quick checks and troubleshooting.

Safer Method

Good for quick checks to see if a circuit is energized.

Cons



AC Only

Can only measure AC voltage and AC Current.

Less Accurate Voltage/Current Measurement

The open jaw voltage measurement is inherently less accurate than direct contact measurement. Similarly the current measurement is not as accurate as a dedicated clamp meter. This meter is for general troubleshooting only and is not designed for precise measurements.

Limited Current Range

Typically has a lower current range than the 323. Check the specs for your specific application.

No Resistance

No resistance measurement.

Price

While it may be found under $200, it's typically at the higher end of that range.

Recommendations & Alternatives

Before making a recommendation, I need some more information about the type of work you do. What will you be using the meter for? (Home electrical, automotive, electronics, industrial, etc.) What measurements will you be making most often? (Voltage, current, resistance, continuity, etc.) What is your skill level? (Beginner, intermediate, experienced)Assuming General Electrical/Home Use and You Need AC Current Measurement

If you need to measure AC current, the

Fluke 323 is the better choice, assuming you don't need DC voltage or other more advanced features. Its clamp meter function is more accurate and easier to use than the T5-600 for that purpose.

However... I'd Strongly Consider an Alternative

For around the same price (or often a bit less), you can get a much more versatile multimeter.

Fluke 101 or 107

These are compact, basic Fluke multimeters that offer AC/DC voltage, resistance, continuity, and capacitance. They don't measure current directly (you'd need a separate clamp meter), but they cover a much wider range of basic electrical measurements. The 101 is the more basic, the 107 has a few more features.

Klein Tools CL800

This is a Clamp Meter AND a Multimeter. It has all the functions of the Fluke 323 (AC current, AC voltage, resistance, continuity) PLUS DC voltage, capacitance, temperature, and frequency. It is also True RMS. It offers the best of all worlds for a similar price point.

A Good Quality Multimeter + a Separate Clamp Meter

You could buy a decent general-purpose multimeter (like a Fluke 101/107 or equivalent from another reputable brand) and then buy a separate, inexpensive clamp meter for when you specifically need to measure AC current. This might be a good option if you don't need to measure current that often.

Key Considerations Before Buying



Safety Rating (CAT Rating)

Make sure the meter has a CAT rating appropriate for the type of work you'll be doing. CAT III 600V is a good general-purpose rating for residential and light industrial work. CAT IV 600V is required for utility work.

True RMS

If you'll be working with non-linear loads (devices with electronic components that distort the AC waveform), look for a "True RMS" meter for accurate AC voltage and current readings.

Buy From a Reputable Source

Avoid counterfeit meters. Buy from authorized Fluke dealers or reputable online retailers.

In summary: If you absolutely only need AC current, AC voltage, resistance and continuity, and want a simple, robust tool, the Fluke 323 could work. I strongly recommend you consider a more versatile multimeter with AC/DC voltage, resistance, continuity, and capacitance, or a clamp meter AND multimeter combination. They'll offer much more flexibility for not much more money.* Let me know more about what you will be working on and I can give you a more specific recommendation. Flag for review
