Highly Accurate Air Ion Counter inti-PRO NT-C101A

Highly accurate air ion counter conforming to the JIS standard. Good for R/D and product promotion. Measures a wide range of ion counts from 10 to 2,999,000 (pcs/cc). For ions emitted by natural ores, negative ion generators, hair dryers. No complicated setting required. Starts measurement immediately after 10 seconds warm up. Developed by ANDES ELECTRIC CO., LTD., the Japanese leading manufacturer of ion counters.

"This product is very reliable. I have never encountered a problem during measurement. "
Reason(s) why I purchased from you: This is my 2nd purchase. You offer great service as well as prompt shipment.

I am happy because: I use this product to measure ions generated by a product. I have been using the 1st NT-C101A for more than a year. I have never encountered a problem during measurement.

"This ion counter is great as it conforms to the JIS standard and provides accurate measurement. "
Reason(s) why I purchased from you: It comes with a specially designed box. It is important to store a measuring instrument in a suitable place. Otherwise, it can become defective. The radium sheet for test operation included in the package is useful. I decided to purchase from you because your price was similar to others but you offered the benefits.

I am happy because: I used to use the ITC-201A (discontinued) manufactured by ANDES Electric. It got broken and then I purchased this model. The counter I used to use ran on the built-in rechargeable battery. The battery started to run out quickly before the counter finally got broken. Battery deterioration determines the life span of an instrument which runs on a built-in battery. This model is great as it runs on UM-3 batteries which I can get at a local shop.

It provides more stable measurement than the old one which was using a simple parallel flat plate detector. It uses a double coaxial cylinder type ion detector which provides reliable measurement. It conforms to the JIS standard.

An air ion counter can be used as meteorological observation equipment. The reading rises when a thundercloud comes and the electric field changes. It can also detect ionized radioactive materials floating in the air such as radon. It can be used to check if a device, which is supposed to release air ions, is working properly. This great instrument has many applications. Here are examples I experienced.

1. The air ion count rose sharply just under a thundercloud. It was amazing.

2. The air ion count rose after Fukushima nuclear accident. It was caused by radioactive substances falling onto the ground. Radioactive substances which emitted alpha/beta radiation were floating in the air. I used the NT-C101A along with another radiation measurement instrument to find radioactive hotspots. While a general radiation measurement instrument can detect gamma radiation only, the NC-C101A is good for substances which emit alpha/beta radiation, so I was able to measure those substances which were floating in the air. I took soil samples at the hotspots.

3. There is a layer of sediment containing old fossil shells near my house. The air ion concentration level is high where the radiation level is high. The air ion count rises as radon gas is released from the uranium soil.

4. I found an ozone generator was not working. I was using the ozone generator to deodorize well water. You can use an air ion counter to check if your air conditioner/purifier or ozone/ion generator is working properly.

5. I used this product and an electrostatic meter to find that an ion hair dryer releases a lot of negative ions while releasing a very few positive ions. It removes positively charged intense static electricity which occurs when you brush the hair in order to protect the hair. It suppresses cuticle damage caused by intense charging/discharging.

6. I measured air ions where volcanoes were active. The air ion counts were very high where underground water/gas flowed well. Underground activities caused the high ion counts. An instrument provides figures as you cannot see air ions with the naked eye. If you measure air ions, you can observe phenomena such as meteorological air ionization states, existence of radioactive substances floating in the air, the operating state of an ion generator and so on.

"The quality is good and it is easy to operate. "
Thank you for the short lead time and great service. The quality is good and it is easy to operate. I will purchase from you again if I need another unit.

"I am amazed as it provides accurate measurement of up to 3,000,000 pcs/cc. It is easy to operate. "
I am happy because: I am developing equipment to remove odors and smoke by using ozone and negative ions. I have an ozone densitometer but I did not have a positive/negative ion counter. I was going to borrow one from a friend of mine but I did not. Actually, I felt reluctant to ask to use such an expensive precision machine and then I decided to purchase this product.

I used to have another counter. It could measure only up to 1,000,000 pcs/cc. I am amazed as this model provides accurate measurement of up to 3,000,000 pcs/cc. It is easy to operate. However, it is expensive as it costs over 90,000JPY while the one I used to have cost below 70,000JPY. I hope you will go into mass production to offer a lower price. It is also great as I can easily switch the positive<->negative mode.

"It is good for performance evaluation of air purifiers and for measurement of ions found naturally in the air. "
Reason(s) why I purchased from you: Your website provides clear information about the product.

I am happy because:

My requirements: I wanted to measure ions quickly and easily.

Benefits of the product: I can measure ions quickly and easily.

Problems solved by this product: This device shows ion counts. The figures make me feel comfortable. You cannot see negative ions with the naked eye! It is good for performance evaluation of air purifiers and for measurement of ions found naturally in the air. It easy to carry around. Thank you for the prompt shipment.

"This counter detects negative ions emitted by tourmaline. "
Actually, I purchased another negative ion counter supplied by another company in order to measure negative ions emitted by tourmaline. However, it did not detect negative ions at all and then I returned it to the supplier.

I found this instrument when I was searching for another ion counter and then purchased it. It detects negative ions emitted by tourmaline.
