Highly Accurate Air Ion Counter MOC-320

  • measures low-density ions accurately

  • conforms to official standard

  • designed to minimize influence of ambient conditions

  • displays ion data in waveform on your PC






  Settings Manual

This precisely designed, capacitor detector provides highly accurate ion measurement.

It is designed to minimize impact of static electricity which can cause inaccurate measurement.

The MOC 320 provides accurate ion measurement in ranges down to 10 ions/cm3.


  • You can manually switch to the positive/negative ion measurement.

  • It conforms to the official standard for measurement method of airbone ion density which rigorously defines the methodology to measure ion density.

Ion Count



The MOC-320 ion counter:

  • measures a wide range of ion counts from 0-2,000,000 (pcs/cc) with high accuracy

  • runs on single phase 100-240VAC.

  • is easy to carry around.

  • weighs approx. 1.5kg.

  • runs on the rechargeable built-in battery.

Specifically designed software


Using the specially designed software, which comes with the counter, you can save, open and print out files which contain the following data. It will help you to make a report. Great for making a report!

  • Ion waveforms

  • Maximum/Minimum/Average ion count

  • Date/Temperature/Humidity

  • * Interface: RS-232C (USB via conversion cable)
    * OS: Windows 98/Windows ME/Windows 2000/Windows XP/Windows Vista/Windows 7


    You can turn off the air suction fan to save power and to prevent an unnecessary load. Fans built into air suction type air ion counters generally consume a lot of power.
