MEASURING RANGE:10000 --- 19,990,000(ions/cc). Please note that the packaging does not contain batteries! !
LCD DISPLAY: display value units for the million, the maximum reading 1999.
SIMPLE AND SMALL DESIGN:This air ion tester is easy to carry as there is a wrist strap, and it is used to static from you.
APPLICATIO:This air ion tester is designed for test high level concent ion of negative or positive air ion. This instrument can be used to determine whether the negative ion polarity produced by air negative ion gene or or air purifier is correct, and the concent ion of ion concent ion can be estimated .
EASY TO READ:AIT (P) anion ion gauge is AIT gauge improved, it is the biggest difference between the AIT is the maximum value of the measured air ions remain on the display, it will give the instrument readings more stable.
