"Easy to read. The AIT (P) Anionic Ion Meter has an improved AIT calibration, AIT is the highest value of ions measured in the air that remain on the display, providing more stable instrument measurements."
"Simple and practical design. This ion tester is easy to carry, very easy to hang, it is a necklace."
"Application: This air ion tester was designed to test the concentration of high levels of negative or positive ions. This instrument can be used to determine whether the polarity of the negative ions produced by the negative ion generator or air purifier is correct, and to estimate the ion concentration."
"Measurement range: 10,000 --- 19,990,000 (ions/cc)"
"LCD display: shows the value unit in parts per million, maximum readability up to 1999"
