What is the hertz of this machine?

I can't find any information on the list one other than through the company they're very um and they're very hush hush about it I think it's like a snake oil app instructions were very brief and singing you can't return it to the company it doesn't work don't buy it

The instructions state Volts 120 VAC: Hertz:60 hz- plug into a grounded 3 prong outlet. do not remove ground prong do not use adapter, do not use extension cord.

The noise level is moderate and what would be expected for what the machine does. The noise has not been an issue for me.

This is hard to answer because the manual is very poor. About what you would expect from the Chinese. The speed adjustment has arbitrary numbers from 1 to 20. I think it goes from 10hz to 30 hz. But I cannot be sure.

Not sure. More than enuff for average listening. If I have to crank it up because it is loud in the shop it drains the battery faster. If you don't care about the battery... It is ridiculous!!!!

I can't tell you in decibels, but my experience is that it is typical for a cordless vac. Quieter than a shop vac. Would buy this again in a heartbeat, the only thing I wish it had was a constant "on" switch in addition to the trigger switch.

Honestly...I wouldn't worry about the KHz. It is a great machine for the price. Nice looks, functions well and again...far less $$$ than in the dental catalogs.

If you got a model specifically for your power and hertz. U.S. specs are 110/120 60hz

I can't tell you in decibels, but it is pretty loud. Too loud to operate in the morning when some are still sleeping

It's between 77 and 80 according to the app "Decible Ultra." The sound is a low hum not the normal high pitch whine of most dryers. My old hair dryer was 90 decibles. For comparison it shows that the sound of a running toilet is 62 Decibles and a completely silent room is 40 Decibles.

Mine is 120-130 VAC 60 HZ. Goodness, all the way from the Land Down Under to Memphis, TN USA? Wow. I have no idea what your standard electric power is in Australia. Oh, and one other thing, if it has a 120 to 240 switch on it somewhere, I don't know, but it is 0130HRS (1:30 AM) here right now, so I will have to wait and get back to you tomorrow. The thing is packed up in my shop out back. Later Jude.

Tale Gunner offered the best answer; the picture on the Amazon product page shows a 230v/50Hz machine (although US buyers receive 110v-130V/60Hz units), so you should take care to ensure you get the right version sent Down Under. Cheers!

According to the computer properties screen, and the box, it is 3.5ghz. I think that was in my review of this product, too.

Sorry it took so long but had to ask someone else as this was a gift.. It is 27.145 mhz

Hey. I really wish I could help you but I have no idea on an ACCURATE frequency range. I remember reading some stuff when I bought them, but that was only what the company or Amazon claimed about them. I don't know if there's a way to measure, but I don't have any tools for that kind of thing.

I'm unsure but, I think it will affect it's operating speed. Hertz in this case refers to alternating current cycles per second.
