Portable Air Ion Tester Meter - Mini Negative Ion Counter for Car & Home, Measures Air Quality - Perfect for Negative Ion Generators, Air Purifiers & Indoor Environment Monitoring

Product Description

Features:This air ion tester is designed for test high level concentration of negative or positive air ion. 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. With it you can estimate whether the air ion generator or air purifier is working in good state. Simple and small design, easy to carry, very easy to hang as a necklace Measuring range:10000 --- 19,990,000(ions/cc) Resolution: 10000 (ions / cc) Compact, easy to carry Can show positive and negative ion concentrations For a variety of negative ion generator, air purifier, air conditioning, high concentration of the ion source to measure Usage: 1. Switch to the "ON" position. 2. keeping the thumb and the square in front of the sheet metal, the metal plate toward the back of the air tested negative ion generator, and tested the closer air anion generator tester readings higher, whereas smaller. Therefore, to ensure the accuracy of the measurement results, leave the meter and test negative ion generator to maintain an appropriate distance. 3. the measurement process, do not touch the metal piece to the back of the instrument, otherwise it would be inaccurate readings.
