Need advice on Clamp Wattmeters

Hi members
I am looking for inexpensive handheld (maybe clamp) meter which can measure power factor, Power KW or HP equipment & other basic things voltage, ampere, frequency. I'm working with 3 phase motors and power so I need an equipment for the same. I cannot go beyond 250$ I know its low but I wish to know if anything is near that range?
Thank you

Hi Mudz, I do not believe that a Clamp Wattmeter is available. One needs potential and current to derive wattage. While the clamp meter will give you current if calibrated for a particular system it can…

There are many "Clamp on Watt meters" but as John has already stated, clamping alone is not enough

The clamp will measure the current, then probes (Same as standard DMM) will be used to measure the voltage, the meter will then do the math for you to show the power.

for instance here is a fluke that can do the job (And alot more) Wattage Meter | Electric Power Meters | Fluke 345 Power Quality Clamp Meter
