操作说明：

１、连接仪器的接地线

２、选择确定ＰＯＬＡＲＩＴＹ在+或-,确定测定正、负离子

３、直立仪器，旋钮在OFF，按纽的开关放在STANDBY，然后然后旋钮至19.99×10n;

４、热机1分钟，当数字不变化时（基本在一个中心变化），按下按钮到RE-ZERO，并且保持3-5秒；

５、当显示的数字在-0.02-0.02时，就已经稳定；如果不稳定，需要重新调零；６、测量时，按纽的开关放在MEASURE就开始测量；

７、根据显示的数值的大小，旋钮可以跟踪旋至不同的量程范围上； 如果在测量过程显示数字1，则应调节到大一量程范围档位；

注意事项：

1、测量时，要保持空气的相对静止，不流动，同时测量人员应远离一个手臂左右；

2、电池电压低于7.5V，应该更换电池，待机情况下（STANDBY），电池使用时间约为10小时；测量情况下（MEASURE），电池使用时间约为2小时，否则，测量的结果会产生很大误差；

3、不要联续开机测定；

4、读数要取出现的数值范围的中间读数。
 

The Air Ion Counter measures the number of positive and negative ion in air.

Available Options:
AC Adaptor: $50 Rechargeable 9V Lithium-Ion Battery System (with charger): $75

Production Description:
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" 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. For these applications, models with ranges of 20 million and 200 million ions/cc are also available. (Range can be specified on the checkout page; all three ranges are $470.)

Output Description:
A plug (included) can be inserted in the left side of the meter to monitor the output, which is a slowly-changing analog voltage. This is a stereo phone plug identical to the plug on small headphones in which the ground has been cut. An output of +1.999 volts (or -1.999) represents full-scale of the meter, regardless of which RANGE is selected.

Option Description:
The rechargeable battery system (Lithium Ion battery at full charge runs six hours at maximum drain, recharges in three hours, has 500-1000 charge cycles of life). Both the AC adapter and the charger for the rechargeable system operate from 110 to 250 VAC (50 to 60 Hz), and either can power the meter directly. If the AC adapter is ordered, it disconnects the internal battery when plugged in, and it does not recharge the batteries.

Air Ion Counter Operation:

Air is sucked in at the top (photo), is measured, and exits at the bottom. The display shows the ion count within 2 seconds and it continues to display the ion density in the air, showing any changes within 2 seconds after they occur. The POLARITY switch determines whether + or - ion density is displayed. (In the photo, negative ion density is being measured.) To conserve power, the switch on the right side can be flipped to STANDBY; this turns the fan off and stops the measurement. A rotary offset control fine-tunes the internal amplifier so the display reads zero if no ions are present (or whenever the meter is on STANDBY). No adjustment of this is needed unless the temperature changes significantly. An analog output jack is present, which is useful for long-term automated monitoring. The meter uses a standard 9 volt battery, but an AC adapter and a rechargeable battery system are two options.

Please note: solids do not produce ions unless there is an energy source (such as radioactivity, high voltage or heat above about 600° C). For example, neither tourmaline nor "diodes" produce any ions at room temperature unless radioactive material has been added. However, liquids evaporating can produce ions.
 

1. When ordering the 20 million ions/cc model, multiply range and resolution by 10. For the 200 million model, multiply by 100.

2. The unpredictable nature of ion self-destruction in the air just outside the meter makes more accurate measurement impossible (some ions are lost as air is redirected, positive and negative ions neutralize each other spontaneously, etc.)
