Easy operation! It is possible to measure positive ions and negative ions by switching.
The Air Ion Counter NT-C101A is equipped with a highly reliable coaxial dual cylindrical sensor, and the measurement values are calculated based on a conversion formula in accordance with the JIS B 9929 standard. Its lightweight and compact design make it portable, making it ideal for outdoor measurements. It can be used for the development and promotion of products related to negative ions, as well as for quality verification (also suitable for measuring ion generators and ion dryers), and for research on natural air ions (such as those found in waterfalls, rivers, forests, mountains, etc.). 【Features】 ○ Achieves miniaturization with a unique structure ○ Capable of measuring a wide range of ion quantities (from 10 to 2,999,000) ○ Warm-up time is 10 seconds ○ Dual power supply system with AC power and dry batteries ○ Can be placed vertically or horizontally Please contact us for more details.
