Counting ions in the atmosphere. This atmospheric-ion counter relies on a fan to draw air through the instrument. A thin brass plate inside a conducting rectangular tube then detects either positive or negative ions in the airflow. The circuitry will detect a current (amperage) of 10 to the minus-15th power. Est. cost: $60.
