Measures Positive/Negative Ions Simultaneously, Wide Range, Good for R/D & Product Promotion


✔ Measures Positive/Negative Ions Simultaneously


The NKMH-103 is an affordable ion counter yet measures positive/negative ions simultaneously.

Unlike other ion counters in this price range, you do not need to switch to the positive <-> negative ion measurement mode. This model simultaneously measures both ions and displays the ion counts on the LCD display.


✔ Measures up to 19,990,000 (pcs/cc), Ultra Wide Range

The NKMH-103 measures 100-19,990,000 (pcs/cc). There are very few ion counters which can measure over 10,000,000 (pcs/cc).

This ion counter is good for measurement of 2,000-300,000 (pcs/cc) ions emitted from negative ion products up to over 10,000,000 (pcs/cc) ions generated by high-performance ion generators.

The NKMH-103 is not good for low density ions. The NT-C101A is available to measure ions in the range of 0-10,000 (pcs/cc).


✔ Good for R/D & Product Promotion

It is good for R/D & product promotion as it clearly shows the ion count.


Lightweight and Compact Body, Runs on a Battery or AC


✔ Lightweight and Compact Body



This product weighs 770g (including the battery), so it is easy to carry around. Ion tester good for outdoor use!


✔ Runs on a Battery or AC



This ion counter runs on x 006P dry battery or 100-240VAC/50-60Hz via the AC adapter. You can use it in most countries.


How to Operate


 1. Air ion measurement

Please note: Air ion measurement can be greatly affected by ambient conditions such as temperature and humidity.

(1) Use it on a stable desk or table. (2) Do not touch or move the counter during measurement. Static electricity can cause inaccurate measurement. (3) Proper grounding provides more accurate measurement.

 Turn on



 Measurement & Reading

No setting or calibration is required. You just place the sample close to the air intake part, turn on the ion counter and wait 30 seconds before you start to measure ions. You can refer to Actual negative ion measurements.

The actual ion count is [the reading] x [the selected measurement range].

e.g. The 102=100 range is selected.
Positive ion: 008 x 100 = 800 (pcs/cc)
Negative ion: 018 x 100 = 1800 (pcs/cc)




You can change the measurement range at any time.


 Measurement range

You can select:
102 range
100-199,900(pcs/cc)
103 range
1,000-1,999,000(pcs/cc)
104 range
10,000-19,990,000(pcs/cc)


 2. DC analog output

You can use the cable, which is included in the package, to connect a DC voltage meter or digital multimeter to the ion counter. DC voltage, which is in proportion to the ion count *1 *2, is extracted from the counter. This allows you to remotely monitor the ion count. You do not need to stay close to the counter during the measurement!

*1 1mV/1digit
*2 +/-1V is outputted when the reading is +/-1000.

Q & A


Q & A: Ion counter

(1) How long do I have to wait after I turn on the counter?
You have to wait 30 seconds. No complicated setting or calibration is required before measurement.
(2) Do I have to perform zero adjustment before measurement?
No, you do not. The counter is automatically calibrated.
(3) What is the ideal distance between the detector and the sample?
There is not an ideal distance. However, the ion count detected by the counter can be lower than it actually is when the sample is too far away from the counter. 10mm +/- will be fine. Please be sure that the sample never makes contact with the detector.
(4) Can I select a measurement range for positive ions and another range for negative ions?
You cannot select different measurement ranges for positive and negative ions. They are simultaneously measured within the same range.
(5) Do I have to wait 30 seconds after I change the measurement range?
We suggest you should do so because it provides more accurate measurement.
(6) Can I store the ion data in the counter?
No, you cannot.
(7) Can I measure ion densities in water?
No, you can't. This ion counter is for air ions.
(8) What is the lowest ion density this counter can measure?
It is 100 (pcs/cc).
(9) Do I need to adjust or calibrate the detector?
No, you do not need to.
(10) Does this counter require grounding?
We suggest you should ground it because it provides more accurate measurement.
(11) I cannot find a measurement tolerance in the specs. Why?
This is because there is no official standard to measure air ions and the tolerance. Measurement tolerances can be found in specs of products supplied by other companies but they can be theoretically calculated values.

We inspect every counter prior shipping and compare the actual measurement with that of a precisely calibrated ion counter to make sure that the tolerance is within 10%.
(12) Do you have a users manual written in other languages?
We only have English and Japanese versions.
(13) Can I transfer the DC output signals to my PC?
No, you cannot. It can cause failure of both the PC/counter. You can use the cable to connect a DC voltage meter or digital mulitmeter to the counter.
(14) How can I use the DC analog output jack?
You can connect a DC voltage meter or digital multimeter to the ion counter by using the cable, which is included in the package.

When X is displayed on the LCD, XmV is outputted regardless of the selected Range. The actual ion count is calculated by: X*Range.

(15) Can I use this ion counter in my country? I think the voltage and AC plug are different from Japan.
You can use the NKMH-103 in most countries as it works with AC100-240V and comes with the AC plug adaptors for the countries.

Q & A: Maintenance work

(1) Does the ion counter require calibration? If it does, how often does it need to be calibrated?
It depends on your usage and ambient conditions but we suggest it should be calibrated once a year. We can calibrate your counter. You can feel free to contact us.
(2) How much/long will it cost/take for calibration work?
It will cost 225USD+/- depending on the exchange rate and will take a week or two. We will contact you to give you a quote if the counter needs calibration work.
(3) Can I clean up the detector by myself? If I can, how can I do that?
Yes, you can.
  1. Remove dust from the exhaust fan on the right side panel and inside the detector.
  2. Open the air intake panel cover and use an air compressor if there is a lot of dust inside.
Please note: The detector can wear out prematurely if you clean up too often. Do not rev up the fan too much when you use an air compressor.
If the counter still seems to be working improperly after cleaning up the detector, please contact us.

Q & A: Others

(1) Does this counter come with a warranty?
We offer a one year warranty.
(2) Can I return the counter?
We accept returns within 8 days of delivery.
(3) Do you offer a rental service?
No, we do not.

It shows how the air quality changes depending on ambient conditions as both positive and negative ion counts are displayed.
I am amazed as exact ion counts are displayed in every living environment. I am glad to confirm that the air in a forest is as clean as the air in a room painted with paint containing antioxidative substances. It shows how the air quality changes depending on ambient conditions as both positive and negative ion counts are displayed.

I received the product earlier than expected as you kindly shipped it the day I ordered. Thank you.
I am happy because: I started to promote a negative ion generator named Waterfall Breeze Ion Medic. We considered purchasing an ion counter because we wanted to measure ion counts around the demo unit, which is installed in our shop, and to show the figures to customers. We were advised to visit your website by the supplier of the Ion Medic.   >> Read more
