Air Negative Oxygen Ion Detector KEC900+||Series Overview：
The intelligent negative air ion detector KEC900+II series is the second-generation product upgraded by Wanyi Technology based on the KEC900+ series with an intelligent single-chip computer program. It adopts German imported standard parts and intelligent sampling fans, single-chip computer system control, and direct-reading LCD display At the same time, it adds the functions of maintaining the maximum value, one-key zeroing and average value measurement. It has the characteristics of good consistency, long life, and easy use. An instrument for measuring and demonstrating the negative ion concentration of negative ion generators and their products.
Air Negative Oxygen Ion Detector KEC900+||Series Features：
1. With average value measurement and MAX retention function
2. It can be grounded or installed with an electrostatic shielding plate to prevent electrostatic interference
3. It can measure positive ions and negative ions in the air, and the gear can switch automatically
4. There is a tripod mounting hole at the bottom of the instrument, which is more convenient for outdoor measurement
5. The service life is as long as more than five years, and it can measure the concentration of negative ions in the range of 200 million/cm³
