The Air Ion Counter or ion meter may be utilized for the detection of normal and artificial ions. Natural ions include those generated from the decay of radioactive minerals and radon gas; ions generated by fires, lightning, and evaporating water; ions produced by active water for instance falls, etc.; and ions associated with storm activity. Remark that in fair weather at sea level, general ion counts are about 400 negative and 500 positive ions per cc. Prior to a storm, positive ions increase drastically. During a storm, negative ions raise radically.
The higher range variants of some quality manufactured ion meter may gauge the output and coverage of artificial sources such as ion devices, improperly grounded air conditioning vents, combustion vapor and electrically charged or heated surfaces, and plasma-discharge ions in air and other gases.
The air Ion Counter compensates for wind via the detector plate and polarizing field design. In still air, the ion detector is engineered to gather only somewhere around 60% from the ions. If there is a wind that pushes air by means of the meter quicker than the typical pace, then much more ions per second will probably be traveling by way of the meter. This impact could make the meter read too high, though as a result of the instrument's style, the assortment fraction drops below 60% if the air flow is faster than regular as well as the collection fraction increases above 60% if the air flow by means of the meter is slower than regular, i.e., if wind is blowing into the back with the meter. The net effect is that the Air Ion Counter stays within +/- 25% accuracy in up to 15 km/hr wind in any direction. (For faster air speed, the meter must either be partially shielded or held perpendicular towards the wind.)
