very pleasantly surprised
Never thought it would really work but it did. You really have to take the time to figure it out but it actually produces a meaningful reading. It has to be in very close proximity to the device and it won't read thru walls or cabinets. I tested it on my two room air cleaners and got reading in the 14 to 16 range. I have no idea what the reference is so I can't say much but that the air cleaner is producing ions. But that is all I really wanted to know anyhow. I took the panel off my house air handler and I got a reading of 1400 -1500again I have no point of reference but i know the ion generator is working which again is what i was after.for $50 as opposed to thousands for a meter it's a winner.

Provides no usable readings
I doubt this device has any clue what it is looking for, or how near or far it may be. I wanted something more reliable for measuring negative ions than licking the back of my hand and holding it @ 1/4" from the ion emitters, this electronic device is not what I was looking for. The instructions show that the device must be connected to a hard ground to work, but it is not set up to do so and even if it were there is no way to verify that the ground is properly grounded. I'll be licking the back of my hand from now on.

A little Difficult to understand but I guess it’s working ...
A little Difficult to understand but I guess it’s working ok....I think I still need practice with it. It’s not always consistent.

Detects both positive and negative ions
It came with a battery that I was able to use it immediately. Thank you!Bought this to make sure that my personal air purifier/ negative ion generator is working so I will not worry about pathogens, etc.—the purpose of having the air purifier in the first place. With the current coronavirus scare, this little device gives me a peace of mind.
