AIR ION COUNTER

 

Highly Accurate Air Ion Counter
TNC A101

  • Highly accurate measurements and easy to operate ion counter.

  • Starts measuring ions after 10 seconds' warm-up

  • Measures positive/negative ions by changing the ion measurement mode.

  • Large LCD clearly shows the ion count.

  • Measures up to 3,000,000 ions/cm3.

  • Wide measurement range usually covers negative ions generated by ion generators or hair dryers.

   

Double coaxial cylinder type detector to provide highly accurate/reliable measurement.

The double coaxial cylinder type ion detector is used to maintain an ideal laminar flow.

This detector ensures the TNC A101 provides highly accurate/reliable air ion measurement.

Clear display of ion count

You can measure positive/negative ions by changing the ion measurement mode.

 

 

Selectable measurement interval

You can push the INT switch to make the measurement interval longer when the ion count fluctuates too fast, so that you will be able to read the figure more easily.

   

Easy to carry around

The compact body weighs only 1.3kg and comes with a shoulder strap. It is easy to carry around and good for outdoor use.

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

Production Description:
The Air Ion Counter is a handheld meter designed to measure ion density - the number of ions per cubic centimeter (ions/cm3) 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/cm3 (for comparison, outdoor air typically has 100 to 1000 ions/cm3, 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/cm3 are also available. (Range can be specified on the checkout page; all three ranges .)

    Instructions
 

 

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 .)

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 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.

 

SPECIFICATIONS: Air Ion Counter -10C to 50C, Wind Speeds < 15 km/hr (9 mph)

Range/Resolution1:

million / 10 (ions per cc) Range change is manual.

Accuracy2:

+/- 25% of reading

Noise:

10 ions/cm3 (2 second averaging)

Meter Size:

6.5 x 3.7 x 3.0 inches; 165.1 x 93.98 x 76.2 mm

Weight:

14.8 oz (420 g)

Battery:

9 volt alkaline (~ 2 hour life) at maximum drain.

 
  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.)
