Description of ๐ŸŒฌ๏ธ KT-401 Mini Air Ion Tester: Accurate LCD Display of High +/- Air Ion Concentrations

This Air Ion Tester is designed for test high level concentration of negative or positive air ion. It is effective to test the electric charge on the surface of textile by strict. With it you can estimate whether the air ion generator or air purifier is working in good state. The reading of the tester is correlative to the air ion concentration, but not exactly the number of it. In factor, this tester can only provide you a rough measurement to the air ion source.

Detects both positive and negative ions

It came with a battery which I was able to use immediately. Thanks very much! Bought this to ensure my personal air purifier/negative ion generator is working so I don't have to worry about pathogens etc - to even have an air purifier. In light of the current coronavirus panic, this little device gives me peace of mind.

Pros
  • Impressive
Cons
  • I'll write later

Airflow is important

I don't have this unit but am considering buying one. But please note that sufficient air circulation is necessary. Use a powerful fan in the room where this device is used. Wait a while for the reading to stabilize and, if possible, leave the room at that time. Come back in about 45 minutes and check your reading.

Pros
  • Comfortable to use
Cons
  • Some difficulties

Glorious Truth?! Real love !?

Like a good metal detector looking for a source! The numbers fly up and down! until you do! Big minus 1! Shows Max Out! The square wall wart was weak! And a flat black magic wand with a wire brush looks great! eye opener? opinion changer? Thanks again Revan! Important ? These negative ions are called vitamins in the air! So small! Easy to keep with you!

Pros
  • Inspires confidence
Cons
  • Protection

Doesn't give any useful readings

I doubt this device has any idea what it's looking for or how close or far it might be. I wanted something more reliable for measuring negative ions than licking the back of my hand and holding it 1/4 inch from the ion emitters, this electronic device is not what I was looking for. The manual states that the device must be connected to a hard ground in order to work, but it is not configured for this and even if it were, there is no way to verify that the ground is properly grounded. From nowโ€ฆ

Pros
  • Satisfied so far
Cons
  • Appearance

very pleasantly surprised

Never thought it would actually work but it worked. You really need to take the time to find out, but it's actually worth reading. It must be in close proximity to the device and not read through walls or cabinets. I tested it on both of my room air purifiers and got readings between 14 and 16. I have no idea what the reference is, so all I can say is that the air purifier produces ions. But that's all I really wanted to know anyway. I removed the panel from my home air conditioner and againโ€ฆ

Pros
  • Stable test results
Cons
  • Could have chosen a newer model
