Air Ion Tester High Concentration of +/- Air Ion Portable Negative Ion Concentration Detector With Peak Maximum Hold LCD Display
Description:
This negative ion concentration tester is specially designed to measure the concentration of negative and positive ions generated by an air negative ion generator.
Using this machine, you can determine whether the polarity of the negative ions generated by the air negative ion generator or air purifier is correct, and roughly estimate and measure the level of ion concentration generated.
This tester is suitable for testing various positive and negative ion generators, air purifiers, air conditioners and other high concentration ion sources.
Please dont take it as an precision instrument!
Specification:
Measurement range: 1x10000 to 9999x10000 ions/cm³
Maximum display value: 9999 × 10000 ions/cm³
Can test the concentration of negative ions in the air (For example: living room or childrens room at home, hotels for business trips, forests, etc.)
The tester can truly display the concentration of negative ions in the air, the concentration is different in different places, such as the wind at the concentration is high!
The tester is easy to carry, beautiful and generous.
Power supply: 2 * 2032 button batteries (not included)
Attention: Dont touch the rear square metal of the tester when testing
Package Included:
1 x negative ion concentration tester
