Air Ion Counter Tester NKMH-103 (Bi-polar/ Ultra wide range)
Product Summary
§  This ion counter measures positive/negative ions simultaneously.
§  There are very few products which measure both ions simultaneously in this price range.
§  It has an ultra wide measurement range of 100-19,990,000 (pcs/cc).
§  It is good for R/D & Product Promotion.
§  This lightweight counter weighs approx. 770g, so it is easy to carry around and great for outdoor use.
§  It is easy to operate because no complicated setting is required before measurement.
§  It outputs DC analog voltage, which allows you to remotely monitor the ion count.
