1. This Air Ion Tester is designed for test high concentration of negative or positive air ion
2. This instrument can be used to determine whether the negative ion polarity produced by air negative ion generator or air purifier is correct, and the concentration of ion concentration is estimated
3. With it you can estimate whether the air ion generator or air purifier is working in good state
4. Simple and small design, easy to carry, very easy to as a necklace
5. Measuring range:10000 ??? 19,990,000(ions/cc)

Spec:
Descriptions:
This instrument is a qualitative product, rather than quantitative products, because of the accuracy, only suitable for testing values of negative ion air purifiers and negative ion generator, and there are certain floating customers, if you mind, choose others please, thanks.

For a variety of negative ion generator, air purifier, air conditioning, high concentration of the ion source to measure.
LCD display: display value units for the million, the maximum reading 1999
LR44button battery is required(battery not included)
The maximum value remains (AITP)
AIT (P) ion meter advantages: 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
