Recommendations on Wattmeter

[alphacat]

Hello.
I'd like to purchase a Wattmeter.

The requirements are:
0.1% accuracy level in Watt (0.1W and above), Amps (0.4mArms and above), Volts (~125V & ~250V), Apparent Power (0.1VA and above) and Power factor.

Do you know any good wattmeters that arent much expensive?

Thank you

Apparently you wish to measure power as low as .1W.

What is the maximum power you want to measure?

Asking for .1% accuracy will increase the price.

For low price, you will need to buy a used meter such as these:

Hey, and thank you.

The power range is from 0.1W to 4KW.
The current range is from 0.4mArms to 16Arms.

The accuracy is the most important requirement, and it must be 0.1%.

Have a look at this companys' products:



I have used a PM1000 in the past, worked OK but may not quite make the 0.1% accuracy on power.
The PM6000 probably does though, for a price!

The base price of the PM1000 is US$2250, with .2% accuracy.

The base price of the PM6000 is US$9490, with .02% accuracy.

You can also find such digital meters from Yokogawa.

"Not very expensive" isn't a phrase I associate with instruments like these when purchased new. I have on occasion seen them on eBay at used prices.
