Description
描述
The Air Ion Counter is a handheld meter designed to measure ion density– the number of ions per cubic centimeter (ions/cc) in air. It measures this number separately for positive and negative ions ( and – ions are usually present simultaneously). This instrument is a true ion density meter, based on a Gerdien Tube (Gerdien Condenser) design, and it contains a fan which pulls air through the meter at a calibrated rate. The standard model measures up to 2 million ions/cc (for comparison, outdoor air typically has 100 to 1000 ions/cc, both and -). The 2 million range is sufficient for almost all situations except for measuring very close to electric ionizers or strong radioactive sources.
空氣離子計數器是一種用于測量離子密度的手持式測量儀，在空氣中每立方厘米（離子/立方厘米）的離子數。它測量這個數字分別為正離子和負離子（通常同時存在）。該儀器是一個真正的離子密度計，基于Gerdien管（Gerdien冷凝器）的設計，它包含一個風扇將空氣通過一個校準率計。標準模型的措施，高達200萬的離子/毫升（用于比較，室外空氣通常有100至1000個離子/毫升，兩者和-）。200萬范圍足以讓幾乎所有情況，除了測量非常接近電離子發生器或強放射源。
